I propose to add a function IsHideWindow, that would be similar to WinAPI functions IsWindowVisible.
Now in PB can not be determined visible window.

Yes, this would be usefull! Instead of adding another command I suggest to add #PB_Window_Hidden to Set/GetWindowState() and declare HideWindow() deprecated.

I had this same thought as well but after thinking about it further I decided it would not work.
That is why my post above shows two edits.
Here is why I think it will not work.
GetWindowState() returns a single value.
This is fine as it is now because the window can be in one of three states, normal, maximized, or minimized.
These states are exclusive, the window cannot be in two of these states at one time.
Now if you add "Hidden" to the mix the states are no longer exclusive.
The window can be (normal hidden),( maximized not hidden), (minimized hidden) etc.
The state can no longer be expressed by returning a single value.

It could be made to work if different bits of the return value are used to indicate the states.
You would have to decode the return value using the bitwise and operator '&' with the constant indicating the state of interest.
This would be similar to the way GetGadgetItemState() works.

This would be nice for crossplatform. I concur. +1

True, you're right! Should think longer before posting a suggestion...

Sounds like that IsWindowHidden() seems to be the way!

+1 anyway

But you hid it, so you know it's hidden. No need to check. Use a variable to keep track of it, if needed.

Trond, If we follow your logic, then the PB need to remove function GetWindowState, GetWindowColor, WindowX, WindowY, and many others, because you can use a variable. But will it be convenient?
