Gadget resize CHANGED?

BlitzMax Forums/MaxGUI Module/Gadget resize CHANGED?

I don't even know WHAT has changed, but my old gui code for my synth distorts the window/gadget content now when you resize the window!!!

What is that?

It somehow changes the scaling of everything inside the gadget, but I can't find where or what I have to change to keep it like it used to work?!

Any help is greatly appreciated. <dispair here>

SetGadgetLayout used to just allow for the gadget's area to change, not for the dimensions of content drawn inside.

Does anyone know what I can do to keep it the way it was?

Thanks in advance!

This is actually a bug in the new DX9Graphics module, in BlitzMax v1.36, and so affects MaxGUI graphics canvases too.

Possible solutions are to either apply the fix Mark posted here or, alternatively, add a call to...

SetGraphicsDriver D3D7Max2DDriver

...or...

SetGraphicsDriver GLMax2DDriver

...at the top of your code.

Hmmm...doesn't make a difference so far. :{
Neither openGL nor DX7. That's really weird. But it's only in the new compile. The old compile with the old Blitzmax version (1.30) and what ever was the contemporary MaxGui version- still runs fine. Just when I compile with the new versions it can't handle it. Confuses me, too.

DX9 by the way, does even wilder things, antialiasing the whole stretch, too. LOL (not that that's any help, but at least it shows that DX or GL don't seem to have an influence on what happens!?)

You know, I just wonder if I had missed some important change in setting up gadget layouts or how the behave relative to the window or their original size?! Not sure when or if anything had changed in the last year. (I was away from it for a while)

Remember this code:

SuperStrict

Import maxgui.Win32MaxGUIEx
'DebugStop
Global Window1:TGadget=CreateWindow:TGadget("Window1",68,62,392,246,Null,WINDOW_TITLEBAR|WINDOW_RESIZABLE |WINDOW_STATUS |WINDOW_CLIENTCOORDS )

Global Canvas1:TGadget=CreateCanvas:TGadget(0,0,392,246,Window1:TGadget,Null)
SetGadgetLayout( Canvas1:TGadget,EDGE_ALIGNED,EDGE_ALIGNED,EDGE_ALIGNED,EDGE_ALIGNED )

Global esc:THotKey = SetHotKeyEvent(KEY_ESCAPE,Null)

Function MyHook:Object(iId:Int,tData:Object,tContext:Object)
  Local Event:TEvent=TEvent(tData)

  If event=Null Return Null
  If (Event.ID = EVENT_WINDOWSIZE) Or (Event.ID = EVENT_WINDOWMOVE) Or (Event.ID = Event_AppResume) Then 
		Redraw()
  End If
	Select Event.ID 
 		Case EVENT_KEYDOWN
			Select Event.Data
			EndSelect
		Case EVENT_HOTKEYHIT
			Select Event.Data
				Case KEY_ESCAPE
					Window1_WC(Window1:TGadget )
			EndSelect
		Case EVENT_MOUSEMOVE
			Print Event.x
	EndSelect
 Return tData
End Function

AddHook EmitEventHook , MyHook




Repeat
	WaitEvent()
	Select EventID()
		Case EVENT_WINDOWCLOSE
			Select EventSource()
				Case Window1	Window1_WC( Window1:TGadget )
			End Select
		Case EVENT_GADGETPAINT
			Select EventSource()
				Case Canvas1	Canvas1_GP( Canvas1:TGadget )
			End Select

	End Select
Forever

Function Window1_WC( Window:TGadget )
	DebugLog "Window Window1 wants to be closed"

	End
End Function

Function Canvas1_GP( Canvas:TGadget )
	DebugLog "Canvas Canvas1 needs to be redrawn"
	SetGraphics CanvasGraphics ( Canvas )
	SetViewport 0,0,GadgetWidth( Canvas ),GadgetHeight( Canvas )
	Redraw()
End Function


Function Redraw()
	Local ScaleX:Float = GadgetWidth(Canvas1 )/400.0,ScaleY:Float=GadgetHeight(Canvas1 )/300.0
	SetScale( ScaleX,ScaleY)
	SetGraphics CanvasGraphics ( Canvas1 )
	SetViewport 0,0,GadgetWidth( Canvas1 ),GadgetHeight( Canvas1 )
	SetColor( 208,216,61 )
	SetClsColor( 118,131,184 )
	Cls
	SetColor 255,0,0
	DrawOval GadgetWidth(canvas1)/2-(50*ScaleX),GadgetHeight(Canvas1)/2-(50*ScaleY),100,100
	Flip
End Function

This used to work beautifully with the circle staying in center and resizing in the desired way. Now it's totally shot... 8{

THANKS for reacting so quickly, by the way, I didn't mean to forget telling you that. :}

Hmmmmm... Cheers for the code example - I see what you mean.

Try adding:

SetVirtualResolution GadgetWidth(canvas1), GadgetHeight(canvas1)

...immediately after the SetGraphics CanvasGraphics() call in your Redraw() function.

I guess the addition of virtual resolutions to BlitzMax will have broken most people's MaxGUI canvas sizing code. We should perhaps update the docs/examples so that it also includes this call to.

Strange that it hasn't been reported before (that I know of).

DX9 by the way, does even wilder things, antialiasing the whole stretch, too.

Is this with Mark's patch applied?

Oh, actually, that was before I applied Mark's changes to the mod. I couldn't detect any difference after!

AH THANK GOD! Or rather: Thank YOU!
That works beautifully.... PHEWWWWWW

Yeah, I was already doubting myself there, haha! I had a hunch it was a virtual resolution issue, as that was the only new thing I knew and could think of, hehe.

Sweet!

Thanks again!
