Centering a window
« Thread started on: Apr 5th, 2017, 5:30pm » |
|
I'm having trouble centering a wide window. Other, narrower, windows center nicely using this:
Code:
UpperLeftX=Int((DisplayWidth-WindowWidth)/2)
UpperLeftY=Int((DisplayHeight-WindowHeight)/2)
I also tried various combinations of UpperLeftX and UpperLeftX with no luck - the window opens too far to the right - partly off-screen
Is there some limit to the width of a window that can be centered?
I guess I would settle for all of the window being visible without having to manually drag it.

What is "wide" window?
Up to DisplayWidth it centers OK
If you ask for more, it limits itself to DisplayWidth
in JB it positions partly off- screen (left-ways)
in LBB it positions from 0
Now, from 0 and DisplayWidth - again centered
Or so it works to me.
Code:WindowWidth = 1.5*DisplayWidth 'gange this number, 0.9 1.0 1.1 ...
UpperLeftX=Int((DisplayWidth-WindowWidth)/2)
print UpperLeftX
UpperLeftY=Int((DisplayHeight-WindowHeight)/2)
'nomainwin
open "test" for window as #main
#main "trapclose [quit]"
wait
[quit]
close #main
end

If I change the window type from "dialog_modal" to "window" my program 'works'.
If I change the window type in your code from "window" to dialog_modal, it does not center, but does keep all the window in view.

To center a dialog window you must use a style bit:
Code: WindowWidth = 300
WindowHeight = 300
stylebits #w, _DS_CENTER, 0, 0, 0
open "test" for dialog_modal as #w
wait

dialog modal is different beast
it is positioned based on parent window.
So uppertLeftX doesn't supposed to work (if only you position parent window first I think)
But there are stylebits.
Search on LB forum returned this:
Topic: Stylebit not working!
so
Code:WindowWidth = 0.9*DisplayWidth 'gange this number, 0.9 1.0 1.1 ...
UpperLeftX=Int((DisplayWidth-WindowWidth)/2)
print UpperLeftX
UpperLeftY=Int((DisplayHeight-WindowHeight)/2)
'nomainwin
stylebits #main, _DS_CENTER, _WS_SYSMENU, 0, 0
open "test" for dialog_modal as #main
#main "trapclose [quit]"
wait
[quit]
close #main
end
EDIT
while I search Richard just *knows* ;)
