It probably goes back to the Hollywood 8 version of the Android player.

Ok, I'll take a look.

I think the problem might be solved by delaying things like moai.get("Main", "Height") and GetAttribute(#DISPLAY, 1, #ATTRSCALEHEIGHT) until after the display has settled on its new attributes. It seems like the numbers are different initially (when first started and right after a screen rotation) compared to after a moment.
That seems to be why SetTimeout() helps for the initial scaling.

Revisiting an issue that has been troubling me for a while now...
The following code fixes the proportional scaling issue (kind of).
But the problem is that it requires a SystemRequest() message to be used. Without the message, the scaling is wrong (too long in Portrait mode and too short in Landscape mode); but with the message, the scaling is correct (at least on my phone).

Code: Select all

@REQUIRE "RapaGUI", {ScaleHollywood = False}
@DISPLAY {Title="Test", Color=#WHITE, Layers=True, Width=600, Height=1920, ScaleMode=#SCALEMODE_LAYER, SmoothScale=True, Hidden=True, SingleMenu=True}

DesiredWidth=600
DesiredHeight=1920

CreateBrush(1, 600, 1920, #BLUE)
SetLineWidth(50)
SelectBrush(1)
	Box(0, 0, 600, 1920, #RED)
	Box(#CENTER, #CENTER, 400, 400, #RED)
EndSelect
DisplayBrush(1, 0, 0)

AppGUI$=[[<application id="app">
	<window id="Main" notify="orientation">
		<vgroup frame="true">
			<hollywood id="HWDisplay" FixWidth="false" FixHeight="false" display="1"/>
		</vgroup>
	</window>
</application>]]
moai.CreateApp(AppGUI$)

Function p_RapaGUIEvents(msg)
	Switch msg.attribute
	Case "Orientation":
SystemRequest("Test", "Test", "OK"); THIS IS THE LINE THAT MAKES ALL THE DIFFERENCE
		If moai.get("Main", "Orientation")="Portrait"
			Local ScreenWidth, ScreenHeight
			Repeat
				ScreenWidth = moai.get("Main", "Width")
				ScreenHeight = moai.get("Main", "Height")
				VWait
			Until ScreenHeight>ScreenWidth
			ScreenHeight = ScreenHeight*ScaleFactor-DisplayScreenDiff	
			SetDisplayAttributes({ScaleWidth=100*(ScreenHeight/DesiredHeight) .. "%", ScaleHeight=100*(ScreenHeight/DesiredHeight) .. "%"})
		ElseIf moai.get("Main", "Orientation")="Landscape"
			Local ScreenWidth, ScreenHeight
			Repeat
				ScreenWidth = moai.get("Main", "Width")
				ScreenHeight = moai.get("Main", "Height")
				VWait
			Until ScreenWidth>ScreenHeight
			ScreenHeight = ScreenHeight*ScaleFactor-DisplayScreenDiff	
			SetDisplayAttributes({ScaleWidth=100*(ScreenHeight/DesiredHeight) .. "%", ScaleHeight=100*(ScreenHeight/DesiredHeight) .. "%"})
		EndIf
	EndSwitch
EndFunction
InstallEventHandler({RapaGUI=p_RapaGUIEvents})

Function p_FirstScale()
	ScaleFactor=GetAttribute(#DISPLAY, 1, #ATTRHOSTSCALE)
	Local TempVar=moai.get("Main", "Height")*ScaleFactor
	Local ScreenHeight=GetAttribute(#DISPLAY, 1, #ATTRSCALEHEIGHT)
	DisplayScreenDiff=TempVar-ScreenHeight
	SetDisplayAttributes({ScaleWidth=100*(ScreenHeight/DesiredHeight) .. "%", ScaleHeight=100*(ScreenHeight/DesiredHeight) .. "%"})
EndFunction

SetTimeout(1, p_FirstScale, 100)

Repeat
	WaitEvent
Forever

Any ideas?
If a workaround can be used that does not require me to use SystemRequest(), that would be great.
