Question on the new DIALOG2 approach - TextMate

30 Sep 2008


      Hi,
I'm just rewriting the GetBundles bundle to support the new syntax of  
DIALOG2. In principal it works fine if I take the eventInfo Dict. But  
I came up with a "problem".
I have a NIB containing a NSSegmentedControl for filtering the repos  
Bundles, Review, GitHub, All.
I bound it via Segment Selection > Selected Label to  
Paramters.selcetion.bundleSelection and connected the entire  
NSSegmentedControl to File's Owner 'performButtonClick'. Each Segment  
has its own tag number.
With DIALOG1 I get e.g.:
<dict>
    <key>bundleSelection</key>
    <string>Review</string>
    <key>cancelBtn</key>
    <string>cancelButtonIsPressed</string>
    <key>dataarray</key>
    <array>
    	<dict>
....
then I can check whether there's a returnArgument, if not is there a  
key 'bundleSelection'...
BUT with DIALOG2 the eventInfo Dict gives me:
    <key>eventInfo</key>
    <dict>
    	<key>tag</key>
    	<integer>0</integer>
    	<key>type</key>
    	<string>buttonClick</string>
    </dict>
    <key>model</key>
    <dict>
    	<key>bundleSelection</key>
    	<string>Review</string>
    	<key>cancelBtn</key>
    	<string>cancelButtonIsPressed</string>
    	<key>dataarray</key>
    	<array>
    		<dict>
This would me that I have to deal with both the eventInfo Dict AND the  
model Dict in order to find which button was pressed.
If I have a 'normal' button bound to performButtonClick DIALOG2  
response is:
    <key>eventInfo</key>
    <dict>
    	<key>tag</key>
    	<integer>4</integer>
    	<key>title</key>
    	<string>Rescan Bundle List</string>
    	<key>type</key>
    	<string>buttonClick</string>
    </dict>
Is there a way to put into the eventInfo Dict the title of the chosen  
Segment of a Segment Control à la the 'normal' button event?
My very first idea was to include into TMDNibController.mm
- (IBAction)performButtonClick:(id)sender
...
    if([sender respondsToSelector:@selector(selectedSegment)] & [sender  
respondsToSelector:@selector(cell)])
    	[res setObject:[NSNumber numberWithInt:[[sender cell] tagForSegment: 
[sender selectedSegment]]] forKey:@"selected_tag"];
Then you can deal with unique tag numbers and you only need the  
eventInfo Dict.
Many thanks in advance
