Could you test a softwared switch off ?

Yes, I did.
There was no problem. The window wasn't maximized.
I tried Rashads snipped above: no problem.
Also the 'normal' standby mode didn't any harm.
Only power off/on showed the problem.

Hi Jim!

Yes, Windows is behaving strangely. At first, it looked as if y=900 was a limit
beyond which the window would expand to its maximum size.
When I then reduced the window size again, the window was still enlarged.
I had to go back to <= 600 until I had a constant window size again.
I give up ...

Thank you to all of you for confirming my observation.
So its not only my system with this strange behaviour.
I will stay with WindowBounds(). It serves me as I do not need
any resizing and I do not have to intercept any events.

Another question is wether this is PB only related and maybe
a bug or ...

Using the monitors power switch.

Hi!

Today I observed an unsual window behaviour:
OpenWindow(1, 10, 10, 1024, 920, "", #PB_Window_SystemMenu)
; WindowBounds(1, 1024, 920, 1024, 920)
Repeat
Event=WaitWindowEvent()
Until Event=#PB_Event_CloseWindow
Running this snippet and turning monitor off and on again lets
expand the window ...

$93 versus $22

Interesting:

If I use For/Next, the execution time ist just 50% with Debugger on.
C-Backend is selected and Optimization is enabled.
31106 ms to 69440 ms
Without Debugger: both 0 ms

Hi Rashad!

Thank you for being so patient.

I seems, that your last posting includes what I was looking for.
It never came to my mind using LIG for that, because I didn't
know the existance of #LVS_NOCOLUMNHEADER.
Everything works, no "soft scroll", all lines reachable with
scroll bar and keys ...

Hi Rashad!

Sorry for my late response, but
I noticed a strange ListGadget behaviour.
I could populate the gadget with more than 65561 entries.
Starting with 65562 entries, I was not able to reach entries
greater than 65561 by moving the scroll bar knob with mouse.
The List jumps just to an entry in ...

Hello Rashad!

Thank you for responding.
Your code works as espected and needed (as always).
I'll stick to it.

Is there a way to eliminate this slow moving of list content when
clicking the scrollbar?

Hi Shardik!

Thank you for your answer.

This example doesn't work with LiestViewGadget.

Here you can't use mousewheel.

Hi!

Is there a way to scroll two or more ListviewGadgets synchron
using mousewheel, scrollbar or upper and lower scroll buttons?
Procedure ScrollSynchron()
; what to do here ???
EndProcedure

If OpenWindow(0, 10, 10, 500, 250, "Test", #PB_Window_SystemMenu)
ListViewGadget(1, 10, 10, 235, 230 ...

This code gives a numbers list, I want to compress.
I would like to reach 2 bits per number.
...

Maybe I'm totally wrong and misunderstud the problem.
What about using one bit for each number?
This is what come to my mind after reading this thread (pseudo code):
; Insert IsPrime_x64() here ...

Aren't x.s and x$ two different variables?
So no error.
If so, it should stay that way.

If a varable is declared by same type a second time, it is no error.
It should yield only a warning.

Did you try HideGadget(0, #True) and HideGadget(0, #False)?
Or was it DisableGadget()? Try it.

For Windows only:

Procedure OnExpandAll()
Protected i
SendMessage_(GadgetID(0),#WM_SETREDRAW,#False,0)
For i = 0 To CountGadgetItems(0) - 1
SetGadgetItemState(0, i, #PB_Tree_Expanded)
Next ...
