Ph_WM_STATE_ISHIDDEN, Please Help!

Hi.

I’m trying to get my application to save/restore the current work space. I
have a problem with correctly restoring the minimized window state.

I’m trying to change the Ph_WM_STATE_ISHIDDEN flag inside my window
pre-realize setup function.

The PtWindow documentation for Pt_ARG_WINDOW_STATE says that you can change
the settings to Pt_ARG_WINDOW_STATE before the window is realized.

I’m setting the Pt_ARG_WINDOW_STATE to Ph_WM_STATE_ISHIDDEN in the window
setup function, before the realize. My window always comes up normal. Why?
What am I doing wrong?

If I change the settings for Pt_ARG_WINDOW_STATE in Phab, then whatever I
pick there, is what I get. It seems that changes from the window setup
function are not used at all. Why?

Please help.

Thanks

Augie

PtSetArg(&args[n], Pt_ARG_WINDOW_STATE, Ph_WM_STATE_ISHIDDEN, 0); n++;

You are setting the flag resource wrong. This way you don’t change anything,
because the mask (third parameter) is zero.
Correct is:

PtSetArg(&args[n], Pt_ARG_WINDOW_STATE, Ph_WM_STATE_ISHIDDEN,
Ph_WM_STATE_ISHIDDEN); n++;
