Creating a Flex AIR text editor Part 40

In todays part we will add a check which prevents the user from opening the same document more than once, as well as add the Save All feature.

Go to the doOpen() function. Inside of it we have an internal function called fileLoad which is called once the user selects the file on their hard drive. Here we can check if this file is already open and if it is, throw a warning message instead of executing the code. Add a check with a function fileDuplicateCheck(file.nativePath) as the conditional.

private function doOpen():void {
var file:File = new File();
file.browseForOpen("Open document", [new FileFilter("Text documents", "*.txt"), new FileFilter("All files", "*")]);
file.addEventListener(Event.SELECT, fileLoad);

function fileLoad(evt:Event):void {
if(fileDuplicateCheck(file.nativePath)){
var stream:FileStream = new FileStream();
stream.open(file, FileMode.READ);
var str:String = stream.readUTFBytes(stream.bytesAvailable);
stream.close();
str = str.replace(File.lineEnding, "
");
statusMessage = "[ " + new Date().toLocaleTimeString() + " ] " + file.name + " opened";
updateStatus();
tabData.addItem( { title:file.name, textData: str, saved:true, location:file.nativePath} );
tabSelectedIndex = tabData.length - 1;
tabChange();
updateTextSize();
}else {
Alert.show("File " + file.name + " is already open","Error");
}
}
}

This fileDuplicateCheck obviously returns a boolean value - true if this file has no duplicates, false of this file is already open.

The check is done using a simple loop:

private function fileDuplicateCheck(loc:String):Boolean {
var toReturn:Boolean = true;
for (var i:int = 0; i < tabData.length; i++) {
if (tabData[i].location == loc) {
toReturn = false;
tabSelectedIndex = i;
tabChange();
break;
}
}
return toReturn;
}

As you can see, we also select the tab of that file if a match was found.

Now lets add the save all functionality.

First go to the doSave() function and add a conditional which checks if the current tab has its saved property false. Only execute the code if the saved property is false (theres no need in saving a file with no changes made!).

private function doSave(ind:int, updateIndexNeeded:Boolean = true):void {
if(!tabData[ind].saved){
if (tabData[ind].location != "") {
saveFile(textArea.text, tabData[ind].location, updateIndexNeeded);
statusMessage = "[ " + new Date().toLocaleTimeString() + " ] " + tabData[ind].title + " saved";
updateStatus();
tabData[ind].saved = true;
}else{
doSaveAs(textArea.text, ind, updateIndexNeeded);
}
}
}

Now create a function called doSaveAll(), which calls doSave() on each index using a loop.

private function doSaveAll():void {
for (var i:int = 0; i < tabData.length; i++) {
doSave(i);
}
}

Now go to the tool bar section and find your save all button, set its click property to the doSaveAll function:

<custom:IconButton icon="@Embed(../lib/disk_multiple.png)" toolTip="Save all" click="doSaveAll();" />

Add a Save All menu item to the XML:

<fx:XML id="windowMenu">
<root>
<menuitem label="File">
<menuitem label="New" key="n" controlKey="true" />
<menuitem label="Open" key="o" controlKey="true" />
<menuitem label="Save" key="s" controlKey="true" />
<menuitem label="Save As" key="s" controlKey="true" shiftKey="true" />
<menuitem label="Save All" key="s" controlKey="true" altKey="true" />
<menuitem type="separator"/>
<menuitem label="Print" key="p" controlKey="true" />
</menuitem>
<menuitem label="Edit">
<menuitem label="Undo" key="z" controlKey="true" enabled="{canUndo}" />
<menuitem label="Redo" key="y" controlKey="true" enabled="{canRedo}" />
<menuitem type="separator"/>
<menuitem label="Cut" key="x" controlKey="true" />
<menuitem label="Copy" key="c" controlKey="true" />
<menuitem label="Paste" key="v" controlKey="true" />
<menuitem type="separator"/>
<menuitem label="Select all" key="a" controlKey="true" />
</menuitem>
<menuitem label="Settings">
<menuitem label="Word wrap" type="check" toggled="{pref_wrap}" />
<menuitem label="Font..."/>
</menuitem>
<menuitem label="View">
<menuitem label="Tool bar" type="check" toggled="{pref_toolbar}" />
<menuitem label="Status bar" type="check" toggled="{pref_status}" />
<menuitem label="Line count" type="check" toggled="{pref_linecount}" />
<menuitem label="Side pane" type="check" toggled="{pref_sidepane}" />
</menuitem>
</root>
</fx:XML>

And update the menuSelect function so that it calls doSaveAll() if the selected menu item was Save All.

private function menuSelect(evt:FlexNativeMenuEvent):void {
(evt.item.@label == "New")?(doNew()):(void);
(evt.item.@label == "Open")?(doOpen()):(void);
(evt.item.@label == "Save")?(doSave(tabSelectedIndex)):(void);
(evt.item.@label == "Save As")?(doSaveAs(textArea.text, tabSelectedIndex)):(void);
(evt.item.@label == "Save All")?(doSaveAll()):(void);
(evt.item.@label == "Word wrap")?(pref_wrap = !pref_wrap):(void);
(evt.item.@label == "Cut")?(doCut()):(void);
(evt.item.@label == "Copy")?(doCopy()):(void);
(evt.item.@label == "Paste")?(doPaste()):(void);
(evt.item.@label == "Select all")?(doSelectall()):(void);
(evt.item.@label == "Status bar")?(pref_status = !pref_status):(void);
(evt.item.@label == "Tool bar")?(pref_toolbar = !pref_toolbar):(void);
(evt.item.@label == "Side pane")?(pref_sidepane = !pref_sidepane):(void);
(evt.item.@label == "Line count")?(pref_linecount = !pref_linecount):(void);
(evt.item.@label == "Font...")?(doFont()):(void);
(evt.item.@label == "Print")?(doPrint()):(void);
(evt.item.@label == "Undo")?(doUndo()):(void);
(evt.item.@label == "Redo")?(doRedo()):(void);
savePreferences();
updateStatus();
if (pref_wrap) {
pref_linecount = false;
}
updateTextSize();
countLines();
}

Everything works OK, except for the fact that if there are multiple unsaved tabs that have no location yet (Undefined ones) and you use Save All, the code throws an error. This is due to the fact that multiple browse dialog windows are called out at the same time.

We will work on this in the next part.

Thanks for reading!

Creating a Flex AIR Annotator app Part 21

In this part we begin working on the crop feature of our program.

Ive done cropping functionality before, specifically while making KirShot. I could just copy and paste the big code here, however, I prefer not to, for 3 reasons:

1) The code used is rather big and complex, it is integrated in KirShots particular environment, it would be very time-consuming and tiring to change all the values and references to reuse that code in KirAnnotator.

2) I am going to create a smaller and more reusable set of functions this time, that can be easily integrated in any program later.

3) We already have some usable functions in KirAnnotator - such as calculateRectValues(), which returns an array of rectangle values based on 4 coordinates.

First of all, go to the "stack" ViewStack container and add a new Group object called cropDraw, this will be used to draw the graphics on.

<mx:ViewStack id="stack" change="stackChange();">
<s:NavigatorContent>
<s:HGroup gap="0">
<custom:BigButton icon="@Embed(../lib/folder.png)" subtext="Import picture" toolTip="Open file" enabled="true" buttonMode="true" bWidth="200" bHeight="200" click="importPicture();" />
<custom:BigButton icon="@Embed(../lib/blank.png)" subtext="Create blank" toolTip="Blank page" enabled="true" buttonMode="true" bWidth="200" bHeight="200" click="newFile(); newfileStack.selectedIndex = 1; newfileWindow.height = 160;" />
</s:HGroup>
</s:NavigatorContent>
<s:NavigatorContent>
<mx:Image id="imgHolder" />
<s:Group id="drawGroup">
<s:Group id="drawSprite" />
<s:Group id="tempSprite" />
</s:Group>
<mx:Box id="annHitArea" alpha="0" backgroundColor="#000000" click="openAnnotation(drawArea.mouseX, drawArea.mouseY);" />
<s:Group id="annotations">
</s:Group>
<s:Group id="cropDraw">
</s:Group>
<mx:Box id="drawHitArea" alpha="0" backgroundColor="#000000" mouseDown="drawDown();" mouseMove="drawMove();"/>
</s:NavigatorContent>
</mx:ViewStack>

Declare these 4 variables:

private var crop_rectangle:Array;
private var crop_anchorX:Number;
private var crop_anchorY:Number;
private var crop_drawing:Boolean = false;

In canvasOver(), set cursor to crossCursor if toolbarStacks index is 4:

private function canvasOver():void {
if (toolbarStack.selectedIndex == 2 && drawTools) {
if(drawTools.selectedIndex < 5){
cursorManager.setCursor(crossCursor, 2, -10, -10);
} else {
cursorManager.setCursor(pickerCursor, 2, 0, -18);
}
}
if (toolbarStack.selectedIndex == 4) cursorManager.setCursor(crossCursor, 2, -9, -10);
}

In toolbarChange(), add a new else...if conditional which checks if selectedIndex of toolbarStack is 4. If so, set mouseEnabled of drawHitArea to true and size and coordinates of drawHitArea as shown:

private function toolbarChange():void {
if (toolbarStack.selectedIndex == 2) {
updateLineExample();
drawHitArea.mouseEnabled = true;
}else if
(toolbarStack.selectedIndex == 4) {
drawHitArea.mouseEnabled = true;
drawHitArea.width = content.width;
drawHitArea.height = content.height;
drawHitArea.x = -1;
drawHitArea.y = 1;
}else {
drawHitArea.mouseEnabled = false;
}
}

Now, we can add the crop-related functions. There are 4 functions were adding today - crop_startDraw, crop_stopDraw, crop_moveDraw, and crop_updateDraw.

The first one receives mouse coordinates through parameters and applies their values to anchor variables, sets crop_drawing to true and sets values for crop_rectangle. Calls crop_updateDraw to draw the rectangle on stage.

private function crop_startDraw(mouseX:Number, mouseY:Number):void {
crop_anchorX = mouseX;
crop_anchorY = mouseY;
crop_drawing = true;

crop_rectangle = [crop_anchorX, crop_anchorY, 0, 0];
crop_updateDraw();
}

The second function stops drawing by setting the boolean to false:

private function crop_stopDraw():void {
crop_drawing = false;
}

The third function checks if boolean is true, sets rectangle values with the help of our calculateRectValues() function and calls crop_updateDraw():

private function crop_moveDraw(mouseX:Number, mouseY:Number):void {
if(crop_drawing){
crop_rectangle = calculateRectValues(mouseX, mouseY, crop_anchorX, crop_anchorY);
crop_updateDraw();
}
}

The final function draws the rectangle like this:

private function crop_updateDraw():void {
cropDraw.graphics.clear();
cropDraw.graphics.lineStyle(1, 0x000000);
cropDraw.graphics.drawRect(crop_rectangle[0], crop_rectangle[1], crop_rectangle[2], crop_rectangle[3]);
}

Now we need to call these functions somewhere.

In the beginning of drawDown():

// cropping
if(toolbarStack.selectedIndex == 4) crop_startDraw(drawArea.mouseX, drawArea.mouseY);

In drawUp():

// cropping
if(toolbarStack.selectedIndex == 4) crop_stopDraw();

In drawMove():

// cropping
if(toolbarStack.selectedIndex == 4) crop_moveDraw(drawArea.mouseX, drawArea.mouseY);

Thats all for now.

Creating a Flex AIR Screenshot app Part 14

In this tutorial we are going to improve our screenshot taking tool by adding a few minor changes.

First go to the init() function. In the end of it, add and remove tempHTML object.

addElement(tempHTML);
removeElement(tempHTML);

This is needed, because later in the code we will be calling a loadString() method of this object, but there is a possibility that the element has not been added even once to the stage before the method is called, which throws an error.

Next - goScreenshot() function. Here we add lines to set useCache to false (so that the HTML object always loads the page from scratch, which is essential in our situation) and set scroll policies to off. This is to prevent a situation when scroll bars can appear on full-size screenshot (even though the sizes are correct).

private function goScreenshot():void {
stack.selectedChild = screenshotloading;
urlString = urlInput.text;

addElement(tempHTML);
tempHTML.htmlLoader.useCache = false;
tempHTML.horizontalScrollPolicy = "off";
tempHTML.verticalScrollPolicy = "off";
tempHTML.visible = false;
tempHTML.addEventListener(Event.COMPLETE, onTempLoad);
tempHTML.htmlLoader.load(new URLRequest(urlString));
}

Next function is changeState(). Here we add 2 lines to the loadpage check, these lines remove the Event.COMPLETE listener from tempHTML and call the html loaders loadString() method to open a blank page. This is required to refresh the page. Also, set width and height of tempHTML to 1. Doing this will prevent some component problems.

private function changeState():void {
if (stack.selectedChild == loadpage) {
contentBox.setStyle("horizontalAlign", "center");
urlInput.text = urlString;
tempHTML.width = 1;
tempHTML.height = 1;
tempHTML.removeEventListener(Event.COMPLETE, onTempLoad);
tempHTML.htmlLoader.loadString("<html></html>");
}
if (stack.selectedChild == crop) {
maximize();
canSelect = true;
contentBox.setStyle("horizontalAlign", "left");
cropHTML.htmlLoader.load(new URLRequest(urlString));
cropHTML.width = contentBox.width;
cropHTML.height = contentBox.height - 24;
cropStatus.text = "Loading";
cropStatus.setStyle("color", "#ffff00");
cropHTML.addEventListener(Event.COMPLETE, onCropLoad);
}
if (stack.selectedChild == screenshotsettings) {
screenSettings = [set2, set3, set4, set5, set6, set7];
contSize.text = "Full size (" + tempHTML.contentWidth + "x" + tempHTML.contentHeight + ")";
loadScreenshotSettings();
}
}

Now the exportScreen() function. There are several changes to be mad ehere.

First of all, add a "full" property to the full-size screen item in screensToExport array and set it to true. This way we can later find out which item in the array is the full-sized one.

// add full-size screen to array if checked
if (pref_screensizes[0].checked) {
screensToExport = [ { w:tempHTML.contentWidth, h: tempHTML.contentHeight, full:true} ];
}

Right after the timer declaration, add a piece of code to check for this "full" propertys value and set scroll policies accordingly - off if full is true, auto if full is false.

// create a timer that repeats itself as many times as many items there are in the array
var timer:Timer = new Timer(2000, screensToExport.length);
timer.addEventListener(TimerEvent.TIMER, onTimer);
// set sizes to the first size of the array
if (screensToExport[0].full) {
tempHTML.horizontalScrollPolicy = "off";
tempHTML.verticalScrollPolicy = "off";
}else {
tempHTML.horizontalScrollPolicy = "auto";
tempHTML.verticalScrollPolicy = "auto";
}

The Flex 4 AIR HTML object has size limitations - 4096x4096 is max. For now we will just check if any of the dimensions extend the limit and warn the user using an Alert window. The screenshot of the invalid size will not be exported, all the rest will be saved like normal though. To do this, we have to add a bunch of conditionals like this (starting right after the previous code lines):

if(screensToExport[0].h <= 4096 && screensToExport[0].w <= 4096){
tempHTML.height = screensToExport[0].h;
tempHTML.width = screensToExport[0].w;
}
timer.start();

function onTimer(evt:TimerEvent):void {
// do export for the current size
if(screensToExport[timer.currentCount-1].h <= 4096 && screensToExport[timer.currentCount-1].w <= 4096){
timer.stop();
doExport();
timer.start();
}else {
Alert.show("Cannot export " + screensToExport[timer.currentCount-1].w + "x" + screensToExport[timer.currentCount-1].h + " - dimensions of a screenshot cannot extend 4096.","Sorry");
}
// change the size if this was not the last size in the array
if (timer.currentCount != screensToExport.length) {
tempHTML.horizontalScrollPolicy = "auto";
tempHTML.verticalScrollPolicy = "auto";
if(screensToExport[timer.currentCount].h <= 4096 && screensToExport[timer.currentCount].w <= 4096){
tempHTML.height = screensToExport[timer.currentCount].h;
tempHTML.width = screensToExport[timer.currentCount].w;
}
}else {
// if it was the last size in the array, return to first page
timer.stop();
removeElement(tempHTML);
stack.selectedChild = loadpage;
}
}

So the full function looks like this:

private function exportScreen():void {
var encoder:IImageEncoder;
var bd:BitmapData;
var byteArray:ByteArray;
var folderName:String = (pref_folder)?(folderField.text):("");
var fileName:String;
var file:File;
var fileStream:FileStream;
var screensToExport:Array = [];

if (pref_format == "JPEG") {
encoder = new JPEGEncoder(pref_quality);
}
if (pref_format == "PNG") {
encoder = new PNGEncoder();
}

// add full-size screen to array if checked
if (pref_screensizes[0].checked) {
screensToExport = [ { w:tempHTML.contentWidth, h: tempHTML.contentHeight, full:true} ];
}

// add the rest screens to array if checked
for (var i:int = 0; i < screenSettings.length; i++) {
if (pref_screensizes[i + 1].checked) {
screensToExport.push( { w: pref_screensizes[i + 1].w, h:pref_screensizes[i + 1].h } );
}
}

// if nothing is checked, go to first page and stop code
if (screensToExport.length == 0) {
removeElement(tempHTML);
stack.selectedChild = loadpage;
return;
}

// create a timer that repeats itself as many times as many items there are in the array
var timer:Timer = new Timer(2000, screensToExport.length);
timer.addEventListener(TimerEvent.TIMER, onTimer);
// set sizes to the first size of the array
if (screensToExport[0].full) {
tempHTML.horizontalScrollPolicy = "off";
tempHTML.verticalScrollPolicy = "off";
}else {
tempHTML.horizontalScrollPolicy = "auto";
tempHTML.verticalScrollPolicy = "auto";
}
if(screensToExport[0].h <= 4096 && screensToExport[0].w <= 4096){
tempHTML.height = screensToExport[0].h;
tempHTML.width = screensToExport[0].w;
}
timer.start();

function onTimer(evt:TimerEvent):void {
// do export for the current size
if(screensToExport[timer.currentCount-1].h <= 4096 && screensToExport[timer.currentCount-1].w <= 4096){
timer.stop();
doExport();
timer.start();
}else {
Alert.show("Cannot export " + screensToExport[timer.currentCount-1].w + "x" + screensToExport[timer.currentCount-1].h + " - dimensions of a screenshot cannot extend 4096.","Sorry");
}
// change the size if this was not the last size in the array
if (timer.currentCount != screensToExport.length) {
tempHTML.horizontalScrollPolicy = "auto";
tempHTML.verticalScrollPolicy = "auto";
if(screensToExport[timer.currentCount].h <= 4096 && screensToExport[timer.currentCount].w <= 4096){
tempHTML.height = screensToExport[timer.currentCount].h;
tempHTML.width = screensToExport[timer.currentCount].w;
}
}else {
// if it was the last size in the array, return to first page
timer.stop();
removeElement(tempHTML);
stack.selectedChild = loadpage;
}
}

function doExport():void {
bd = new BitmapData(tempHTML.width, tempHTML.height, false);
bd.draw(tempHTML);
byteArray = encoder.encode(bd);
fileName = pref_destination + File.separator + folderName + File.separator + tempHTML.width + "x" + tempHTML.height + "." + pref_format;
file = new File(fileName);
fileStream = new FileStream();
fileStream.open(file, FileMode.WRITE);
fileStream.writeBytes(byteArray);
fileStream.close();
}
}
