Is Splitter not event hook friendly?

BlitzMax Forums/MaxGUI Module/Is Splitter not event hook friendly?

Hi folks,

if I do the WAITEVENT handling inside a regular loop, then the splitter is acting normal. If I put all the event handling inside a event hook function like is shown inside the documentation, then the splitter doesn't move/react at all. Any ideas?

I have just normal gadgets in my app. Menu, toolbar, tab control, listbox.

Beside the slow redraw of gadgets on top during moving the splitter or resize, it's working as expected and I don't have any problems with it.
Some code?

Function hook:Object(id:Int,data:Object,context:Object)
	'your event handling code here
	'...
	Return data 'add this
End Function

example:

Strict

Import MaxGUI.Drivers
Import MaxGUI.ProxyGadgets

Global wndMain:TGadget = CreateWindow("Splitter Example",100,100,400,300,Null,WINDOW_TITLEBAR|WINDOW_RESIZABLE|WINDOW_CENTER|WINDOW_CLIENTCOORDS|WINDOW_STATUS)
	
	'Create a splitter gadget
	Global spltMain:TSplitter = CreateSplitter( 0, 0, ClientWidth(wndMain), ClientHeight(wndMain), wndMain )
	SetGadgetLayout spltMain,EDGE_ALIGNED,EDGE_ALIGNED,EDGE_ALIGNED,EDGE_ALIGNED
	
	Local tmpSplitPanel:TGadget
		
		'Add a gadget to our left pane
		tmpSplitPanel = SplitterPanel(spltMain,SPLITPANEL_MAIN)
		Global txtEditor:TGadget = CreateTextArea(0,0,ClientWidth(tmpSplitPanel),ClientHeight(tmpSplitPanel),tmpSplitPanel,TEXTAREA_WORDWRAP)
		SetGadgetLayout(txtEditor,EDGE_ALIGNED,EDGE_ALIGNED,EDGE_ALIGNED,EDGE_ALIGNED)
		
			AddTextAreaText(txtEditor, "The quick brown fox jumped over the lazy dogs.~n~n")
			AddTextAreaText(txtEditor, "The quick brown fox jumped over the lazy dogs.~n~n")
			AddTextAreaText(txtEditor, "The quick brown fox jumped over the lazy dogs.~n~n")
		
		'Add a gadget to our right pane
		tmpSplitPanel = SplitterPanel(spltMain,SPLITPANEL_SIDEPANE)
		Global treeView:TGadget = CreateTreeView(0,0,ClientWidth(tmpSplitPanel),ClientHeight(tmpSplitPanel),tmpSplitPanel)
		SetGadgetLayout(treeView,EDGE_ALIGNED,EDGE_ALIGNED,EDGE_ALIGNED,EDGE_ALIGNED)
		
			AddTreeViewNode("Child", AddTreeViewNode("Parent Node", TreeViewRoot(treeView)))
			AddTreeViewNode("Other", TreeViewRoot(treeView))
	
	AddHook(EmitEventHook,hook)
Repeat
	WaitEvent()
Forever

Function hook:Object(id:Int,data:Object,context:Object)
	Local event:TEvent=TEvent(data)
	Select event.id
		Case event_windowclose,event_appterminate;End
		Case event_gadgetaction
			AddTextAreaText(txteditor,"!")
			Return Null
	End Select
	Return data 'comment this line and try to move splitter
End Function

Mmmh, thanks. I will study this to see where the difference is.

@Zeke, thanks a lot. I didn't return the object from the hook function. That was it!!!
