ShowPointer() without mouse activity

[Flinx]

The ShowPointer() function only works when a status change comes from the mouse buttons or there is a movement. This does not bother much, but maybe it can be improved. Here an event should display the pointer when the mouse button is pressed, but this only works if there is further mouse activity after the event.
My test script:

Code: Select all

EnableLayers()
TextOut(10,10,"Start",{Name="msg"})
For i=1 To 100
	Wait(2500,#MILLISECONDS)
	SetLayerStyle("msg", {Text="HidePointer"})
	HidePointer()
	Wait(2500,#MILLISECONDS)
	SetLayerStyle("msg", {Text="ShowPointer"})
	ShowPointer()
Next

I can confrim this. Same happens with Windows 10 Hollywood 9.1.

Hidepointer works fine, but ShowPointer doesnt happen, unless I move my mouse or something.

Yes, I can confirm it too. Will be fixed.

By the way, I remember that moving a layer under the mouse also did not trigger an OnMouseOver event if there was no mouse movement. Maybe this is the same effect?

[airsoftsoftwair]

Have you got an MCVE for that?

[Flinx]

Sure. It was a Layer button. Move the pointer over the box, and then place it in the path of the box.

Code: Select all

EnableLayers()

Function p_blue()
	SetDisplayAttributes({Color=$003377})
EndFunction

Function p_black()
	SetDisplayAttributes({Color=#BLACK})
EndFunction

Function p_Main()
	xp=xp+1
	If xp>GetAttribute(#DISPLAY, 1, #ATTRWIDTH) Then xp=-50
	SetLayerStyle("box", {X=xp})
EndFunction

SetFillStyle(#FILLCOLOR)
xp=0
Box(xp, 100, 50, 50, #GRAY, {Name="box"})
MakeButton(1, #LAYERBUTTON, "box", {OnMouseOver=p_blue, OnMouseOut=p_black})
SetInterval(1, p_Main, 30)

Repeat
	WaitEvent
Forever

Thanks, now I understand the issue but I'm not sure if I'm going to fix this because it can probably trigger lots of unwanted behaviour for scripts that expect the old behaviour. The first issue is clearly a bug, though.

Maybe it makes sense to collect such things, and introduce a global switch for a compatibility mode at some point?

Yes, introducing a compatibility mode would be the only way to fix this.
