Creating a Flex AIR text editor Part 92
The problem with linecount is that when the font size is big, like, over 40 points, 2-digit numbers already dont fit in the narrow box. To fix that, we need to make sure the box size changes according to the font size. Update the updateTextSize() function by adding a line to the beginning of the code which sets the lineCountWidth variables value:
private function updateTextSize():void {
lineCountWidth = pref_fontsettings.fontsize * 4;
tabY = (toolBar.visible)?(toolBar.height):(0);
textX = (pref_linecount)?(lineCountWidth):(0);
var statusHeight:Number = (pref_status)?(statusBar.height):(0);
textWidth = (pref_sidepane)?(width - sidePaneWidth - textX):(width - textX);
tabWidth = textWidth + textX;
var tabbarScrollHeight:Number = (tabData.length * 170 > tabWidth)?(15):(0);
textY = tabBar.height + tabY + tabbarScrollHeight;
textHeight = height - textY - statusHeight;
focusManager.setFocus(textArea);
sidePaneHeight = textHeight + tabBar.height + tabbarScrollHeight;
sidePaneY = textY - tabBar.height - tabbarScrollHeight;
sidePaneX = width - sidePaneWidth;
}
The space for the line count number should be enough for most text files.
Now, we will start working on a comments feature, which is so useful to the developers. In the program, I am going to include 3 types of comments - line comment, block comment and xml comment, since they are the most used ones. The first two (// and /* */) are mostly used in script languages, while <!-- --> is used in XML based languages like HTML.
I am going to put 4 buttons on the tool bar, 3 buttons for the comments and 1 button to remove any comment symbols in the selected area.
I have created custom icons for this feature. Those are comment_line, comment_block and comment_xml. They are all based off comment.png icon from FamFamFams Silk icon set. I also used comment_delete.png from the same set as the fourth button.
So in the end I had these icons to use:
Well, now we need to put these icons in the lib directory of our project.
Find the place where the toolbar is created in the code and update it by adding 4 more icons:
<mx:HBox id="toolBar" width="100%" backgroundColor="#dddddd" height="30" visible="{pref_toolbar}" paddingTop="2" paddingLeft="3">
<custom:IconButton icon="@Embed(../lib/page.png)" toolTip="New document" click="doNew();" />
<custom:IconButton icon="@Embed(../lib/folder_page.png)" toolTip="Open" click="doOpen();" />
<custom:IconButton icon="@Embed(../lib/disk.png)" toolTip="Save" click="doSave(tabSelectedIndex);" />
<custom:IconButton icon="@Embed(../lib/disk_multiple.png)" toolTip="Save all" click="doSaveAll();" />
<custom:IconButton icon="@Embed(../lib/printer.png)" toolTip="Print" click="doPrint();" />
<custom:IconButton icon="@Embed(../lib/find.png)" toolTip="Find/replace" click="doFind();" />
<s:Label text="|" fontSize="18" color="#bbbbbb" paddingTop="4" />
<custom:IconButton icon="@Embed(../lib/arrow_undo.png)" toolTip="Undo" enabled="{canUndo}" click="doUndo();" />
<custom:IconButton icon="@Embed(../lib/arrow_redo.png)" toolTip="Redo" enabled="{canRedo}" click="doRedo();" />
<s:Label text="|" fontSize="18" color="#bbbbbb" paddingTop="4" />
<custom:IconButton icon="@Embed(../lib/cut.png)" toolTip="Cut" click="doCut();" enabled="{canCutCopy}" />
<custom:IconButton icon="@Embed(../lib/page_white_copy.png)" toolTip="Copy" click="doCopy();" enabled="{canCutCopy}" />
<custom:IconButton icon="@Embed(../lib/paste_plain.png)" toolTip="Paste" click="doPaste();" enabled="{canPaste}" />
<s:Label text="|" fontSize="18" color="#bbbbbb" paddingTop="4" />
<custom:IconButton icon="@Embed(../lib/zoom_in.png)" toolTip="Zoom in" click="doZoomIn();" enabled="{!fontOpen}" />
<custom:IconButton icon="@Embed(../lib/zoom_out.png)" toolTip="Zoom out" click="doZoomOut();" enabled="{!fontOpen}"/>
<s:Label text="|" fontSize="18" color="#bbbbbb" paddingTop="4" />
<custom:IconButton icon="@Embed(../lib/comment_line.png)" toolTip="Line comment" click="doLineComment();" />
<custom:IconButton icon="@Embed(../lib/comment_block.png)" toolTip="Block comment" click="doBlockComment();" />
<custom:IconButton icon="@Embed(../lib/comment_xml.png)" toolTip="XML comment" click="doXMLComment();"/>
<custom:IconButton icon="@Embed(../lib/comment_delete.png)" toolTip="Delete comment" click="doDeleteComment();"/>
</mx:HBox>
Right now the buttons call 4 empty functions:
private function doLineComment():void{
}
private function doBlockComment():void{
}
private function doXMLComment():void{
}
private function doDeleteComment():void{
}
Also, since the toolbar content width has extended, if the user resizes the window to a too small size, the 4 icons might not fit in the screen. So I decided to increase the minWidth value of the WindowedApplication tag to 700:
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
xmlns:custom="*"
creationComplete="init();" title="Kirpad" showStatusBar="{pref_status}"
minWidth="700" minHeight="200" height="700" width="900">
And heres the whole code:
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
xmlns:custom="*"
creationComplete="init();" title="Kirpad" showStatusBar="{pref_status}"
minWidth="700" minHeight="200" height="700" width="900">
<s:menu>
<mx:FlexNativeMenu dataProvider="{windowMenu}" showRoot="false" labelField="@label" keyEquivalentField="@key" itemClick="menuSelect(event);" />
</s:menu>
<fx:Script>
