How to get size of master ( or current window ) in loop function

[manuel-koch]

How can I get current size of the master window within my loop() function ?

I tried the following

• giu.GetAvailableRegion()
• imgui.ContentRegionAvail()
• imgui.WindowSize()
  but none actually returned the size I initially used for
  wnd := giu.NewMasterWindow("Hello world", 200, 200, 0)
  nor an updated size when I resized the window with my mouse.

I think it was just a misunderstanding of imgui / giu on my part.

The following seems to work for a simple loop function content:

giu.SingleWindow().Layout(
   giu.Custom(func() {
      w, h := giu.GetAvailableRegion()
   }),
   giu.Label("Hello"),
)

The trick is to evaluate the size of the current window within the window code, not outside.

You can get window size by
wnd:= giu.Window("wnd")
w, h := wnd.CurrentSize()
wnd.Layout(....)

@manuel-koch MasterWindow has a method named "GetSize".

wnd := giu.NewMasterWindow("Hello world", 200, 200, 0)
width, height := wnd.GetSize()
