We are using PhWindowOpen to create windows/frames/dialogs (we are *not* using widgets). Is there any way to make a 
window modal?

Re: Create a Modal Dialog

1. You need to write your own window manager event handler. Your code should decide when to allow/disallow window focus 
change for example on a click. This evolves setting up your regions' sensitivity correctly – check out the 
PhWindowEvent_t docs.

2. You may not need to run pwm.

Re: Create a Modal Dialog

That's what I was thinking I would have to do. I was *hoping* I could get the wm to do it for me.

I already have my own event handler loop and was thinking I could have it throw away all mouse, keyboard and wm events 
and only process the expose event. I think I would also have to modify all other windows (that are part of my app) so 
that they  can't be brought to the foreground.

Within one app, you can try to use PhWindowChange() and set info.state_f (PhWindowInfo_t) to  [~]Ph_WM_STATE_ISBLOCKED.

Good idea. I'll give that a try.
