5.40LTS - Moving a window shows it at 0,0 coordinates

Moving a window shows it at 0,0 coordinates half a second :
Code: Select all
OpenWindow(0, 100, 100, 300, 200, "gtk api test")
ResizeWindow(0, 150, 150, #PB_Ignore, #PB_Ignore)
Repeat : Until WaitWindowEvent() = #PB_Event_CloseWindow
(seen on Debian 8-64 / Gnome with PB 5.40LTS 64 bits)

Not a bug, IMHO.
Code: Select all
OpenWindow(0, 100, 100, 300, 200, "gtk api test", #PB_Window_Invisible)
ResizeWindow(0, 150, 150, #PB_Ignore, #PB_Ignore)
HideWindow(0, #False)
Repeat : Until WaitWindowEvent() = #PB_Event_CloseWindow
To be sure there is no bug, try this:
Code: Select all
If OpenWindow(0, 0, 0, 230, 90, "...", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
ButtonGadget (1, 10, 10, 200, 20, "Click me")
Repeat
Event = WaitWindowEvent()
If Event = #PB_Event_Gadget
ResizeWindow(0, Random(500, 100), Random(500, 100), #PB_Ignore, #PB_Ignore)
EndIf
Until Event = #PB_Event_CloseWindow
EndIf

I don't think it's a bug as you displayed it before performing the move, so yes it can be shown until the move is handled by the window manager.

Sorry my sample code was not very complete because I wanted to simplify it at maximum.
The same occurs with a hidden Window, see the snippet bellow :
Code: Select all
OpenWindow(0, 100, 100, 300, 200, "gtk api test", #PB_Window_Invisible)
ResizeWindow(0, 150, 150, #PB_Ignore, #PB_Ignore)
HideWindow(0, #False)
Repeat : Until WaitWindowEvent() = #PB_Event_CloseWindow
Obviously this problem does not occur with gtk2 nor with others OSs.

I see. The problem is with GTK3, which can't move an hidden window, so it's done when unhiding it. So sometimes you can see the refresh

This is the main reason why i stick on 5.31.
Will you fix it?

The problem is we can't fix it, it seems to be a GTK3 oddity as it works properly with GTK2.

I think with PB 5.40, we can also use GTK 2 as subsystem. Or is this wrong?

I don't know exactly how you coded this, but i guess you are calling the
gtk_widget_show_all() method even if the
#PB_Window_Invisible flag is set. I tried to reproduce this behaviour with python and got this snippet:
Code: Select all
from gi.repository import Gtk
w = Gtk.Window()
w.set_default_size(300, 300)
w.move(200, 200) # move this line after show_all, and you see the same as on PureBasic
w.show_all()
w.connect('destroy', Gtk.main_quit)
Gtk.main()
If you run this, everything is ok, but if you move the window after the show_all(), you see the same prblem as in PB.

Could be a workaround then to do the show_all() in HideWindow() if the invisible flag is used. I will test it and get back to you, thanks for investigating !

With PB 5.31 and gtk3 subsystem it works fine, so maybe it is not a GTK3 issue.

I tried the workaround but it doesn't change anything here.

For me, it is fixed in 5.43. May be the same thing than that ? :
