SetFocus() not working?

BlitzMax Forums/Brucey's Modules/SetFocus() not working?

UNZ	(Posted 2013) [#1]

Hi,

I'm trying to create an info frame for a control (let's call it myControl) but without loose of focus.
My thought was to call SetFocus() directly after the child frame is shown but it does not work. Calling SetFocus() of myControl does not return the focus to myControl.
This occurs on linux.

example:

SuperStrict
Framework brl.standardio
Import wx.wxApp
Import wx.wxFrame
Import wx.wxTextCtrl
Import wx.wxstatictext
Import wx.wxPanel

New MyApp.Run()

Type MyApp Extends wxApp

	Method OnInit:Int()
		Local frame:myFrame = myFrame(New myFrame.Create( ,, "wxMax") )
		frame.Show()
		Return True
	End Method
End Type

Type MyFrame Extends wxFrame
	
	Method OnInit()
		Local pnl:wxPanel = New wxPanel.Create(Self , wxID_ANY)
		
		Local s:wxSizer = New wxBoxSizer.Create(wxVERTICAL)
		
		'create a label and a text control that can create a child frame
		Local lbl:wxStaticText = New wxStaticText.Create(pnl , wxID_ANY , "enter an 'a' to open child frame")
		Local txt:wxTextCtrl = New myTextCtrl.Create(pnl , wxID_ANY)
		s.Add(lbl , 0)
		s.Add(txt , 0)
		
		pnl.SetSizer(s)
		Center()
	End Method
End Type

Type myTextCtrl Extends wxTextCtrl
	Method OnInit()
		ConnectAny(wxEVT_COMMAND_TEXT_UPDATED , OnText , Self)
	End Method
	
	'create and show child frame
	Method ShowChild()
		Local child:wxFrame = New wxFrame.Create(Self , wxID_ANY)
		Local lbl:wxStaticText = New wxStaticText.Create(child , wxID_ANY , "I don't want the focus!")
		child.Show() 'child gets focus
		
		SetFocus() 'the focus should go back to the text ctrl, but it doesn't
	End Method
	
	Function OnText(event:wxEvent)
		Local win:myTextCtrl = myTextCtrl(event.userData)
		If win
			
			'create child frame on hitting "a"
			If win.GetValue().ToLower().EndsWith("a") Then win.ShowChild()
		EndIf
	End Function
End Type

Is there another way to do this?

Maybe the problem is that the focus event is triggered within another event (there were bugs in 2.9.4 for keydown-events not getting triggered in some situations). Changed the update event to evt_char without luck.
Observe the focus event chain?

Another option is that there is a fault in wxwidgets as others had problems in macos 5 years ago - which needed a patch.

This issue is the last that I want to fix before the next release of indevIDE.

If there is no solution I will use the default calltip functions of scintilla on linux.
But you have to choose between calltips or autocomp on typing because they override each other which is very annoying when your typing function parameters...

Well, if you are always going to return focus to the originating you could pass the calling control up to the new frame, and have the frame set the focus back once it is finished displaying ?

I try to set the focus back in the example but it doesn't work on linux. It does work on windows though.
Plus the frames should both be visible.
