wxTreeCtrl question

2 questions I suppose, is the wxEVT_COMMAND_TREE_STATE_IMAGE_CLICK event implemented and is it Windows only, I'm assuming yes as that's what it says in the wxWidgets docs. I want to implement checkboxes on tree controls and it mentions this method in the book I have, but it makes no mention in there about being windows only...

I guess you wouldn't have bothered implementing it if it's Windows only which is fair enough, I probably won't use it if that's the case. Thanks!

Well, it's in the list of events for the event handler (in wxtreectrl.bmx), so I guess if the framework raises the event then it will be called by wxMax.

If other platforms don't raise the event, well, I suppose you'd have to work out something else on those platforms, but it all compiles on the three platforms.

Yeh I tried it, but nothing was being raised (Sorry, I should have mentioned that!)

Quick sample here:

SuperStrict
 
Framework wx.wxApp
Import wx.wxFrame
Import wx.wxGenericDirCtrl
 
New MyApp.Run()
 
Type MyApp Extends wxApp

	Method OnInit:Int()
	
		Local frame:MyFrame = MyFrame(New MyFrame.Create(Null, wxID_ANY, ..
			"GenericDirCtrl", -1, -1, 350, 350, wxMINIMIZE_BOX | wxMAXIMIZE_BOX| wxSYSTEM_MENU | wxCAPTION | wxCLOSE_BOX | wxCLIP_CHILDREN))
		frame.Show(True)
 
		Return True
	End Method

End Type

Type MyFrame Extends wxFrame

	Field dirCtrl:wxGenericDirCtrl
	Field tree:wxTreeCtrl

	Method OnInit()
	
		dirCtrl = wxGenericDirCtrl.creategenericdirctrl(Self, wxID_ANY, CurrentDir(),,,,,,"PNG files (*.png)|*.png")
		dirctrl.SetFilter("PNG files (*.png)|*.png")

		tree = dirCtrl.GetTreeCtrl()
		
		tree.Connect(tree.GetId(), wxEVT_COMMAND_TREE_ITEM_RIGHT_CLICK, _OnRightClick, Null, Self)
		tree.Connect(tree.GetId(), wxEVT_COMMAND_TREE_STATE_IMAGE_CLICK, _OnImageClick, Null, Self)
		
		Centre()
 
	End Method
	
	Function _OnRightClick(event:wxEvent)
		MyFrame(event.sink).OnRightClick(wxTreeEvent(event))
	End Function
	
	Method OnRightClick(event:wxTreeEvent)
		DebugLog "item : " + dirCtrl.GetPath()
	End Method
	
	Function _OnImageClick(event:wxEvent)
		MyFrame(event.sink).OnImageClick(wxTreeEvent(event))
	End Function
	
	Method OnImageClick(event:wxTreeEvent)
		DebugLog "You clicked an image!"
	End Method
	
End Type

According to the source (of wxWidgets), this event is raised when you release the left mouse button (click) on a part of an item with a TVHT_ONITEMSTATEICON flag (which is determined by a hit-test).

No idea what a state item is though.

And it is indeed Win32 only.
