Creating a Flex AIR text editor: Part 100

In this tutorial we will improve and change a few things to improve user experience with the program.

The first change we're going to make is make it so that the recent items from recent tab in the sidepane are opened on double click instead of single click. I decided to do that because items are also opened with double click in file browser tab, and I think the behaviour should be the same for less confusion and more user-friendliness.

However, since there is no prebuilt item double click event for the List component that we can listen to, we'll do a little bit of wizardry here.

We can, however, listen for the doubleClick event. We need to keep in mind though, that this event is dispatched when any area in the List component is clicked, not just the items, but blank white area too. That's okay, with a little bit of code we will fix that.

Add a doubleClick listener for the List object and set its doubleClickEnabled flag to true. The event handler for the doubleClick event is a function called recentDoubleClick(), with "event" passed as the parameter.

<s:List id="recentList" width="{sideContentWidth}" height="100%" dataProvider="{pref_recent}" labelField="label" doubleClick="recentDoubleClick(event);" doubleClickEnabled="true" />

In the function, we check if its the dataGroup of recentList is the target of the click. If it is not, call selectRecent():

private function recentDoubleClick(evt:MouseEvent):void {
if(recentList.dataGroup != evt.target){
selectRecent();
}
}

Another thing we're going to change is make it so that whenever a tab with some content in it is opened (and that happens only when loadFile function is called) the caret position should go to the end of the content. We do this by specifying selectedActive and selectedAnchor properties of the item and set them to the last character's position:

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

The next thing we're doing is making sure that when the user chooses to delete the file from the computer, it shouldn't ask if we want to save the file. This is done by changing the closeTab() function to removeTab() in doDelete():

private function doDelete():void{
Alert.show("Delete " + tabData[tabSelectedIndex].location + " from computer?", "Confirmation", Alert.YES | Alert.NO, null, confirmDelete);

function confirmDelete(evt:CloseEvent):void {
if (evt.detail == Alert.YES) {
var file:File = new File(tabData[tabSelectedIndex].location);
if (file.exists) {
file.deleteFile();
removeTab(tabSelectedIndex);
statusMessage = "[ " + new Date().toLocaleTimeString() + " ] " + file.name + " deleted";
updateStatus();
refreshFileBrowse();
}else {
Alert.show("File not found at specified location!","Oops!");
}
}
}
}

Finally, let's add a Snippet icon to the tabbar. It should have similar behavior to Find/Replace icon, except that it will open a different tab. Lets reposition the Find icon too so that they would be positioned next to each other on the tabbar.

<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();" />
<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/find.png')" toolTip="Find/replace" click="doFind();" />
<custom:IconButton icon="@Embed('../lib/book.png')" toolTip="Snippets" click="doOpenSnippet();" />
<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>

As you can see, the Snippets icon has the same picture as the snippets tab icon (book.png), and it calls doOpenSnippet() on click.

The function is here:

private function doOpenSnippet():void {
pref_sidepane = true
sidePaneButtons.selectedIndex = 2;
savePreferences();
updateTextSize();
countLines();
}

That's all for today!

Тестировал Ваш редактор, нашел такой баг с печатью - на принтер выводиться только одна строчка (первая) текста, дальше чистый лист... хотя отправлял на печать многостраничный документ.
В целом очень здорово получилось) буду дальше испытывать.
Спасибо.

Спасибо за находку. После тестирования выяснилось, что такая проблема возникает только, если в тексте нет ни одного переноса строки. Решив проблему, обновлю исходники.

We were discussing a bug that prints only one line of text if there are no new line characters in the whole text. I will try to fix this and update the sources.
