Hi guys,
is there a way to detect if there's a PopupDialog open? I'm referring to those for Editable Poly objects like Extrude, Bevel, Bridge, and so on. Knowing exactly which Popup is open isn't strictly required.

I need to perform some refreshing in my cache if topology/geometry is changed upon sub object selection changes.

Thank you very much.

I believe you can use this function to detect if the dialog is open: windows.getChildrenHWND

then use this to press a button:
windows.sendMessage

the hard part (i guess) is looking for the correct integer HWND.

I haven't actually used these functions myself but I hope this helps. :)

edit:
stumbled upon these today, search for these in the help file:
DialogMonitorOPS

Thanks Galagast,
I'm going to look into it, seems to be what I need. Just found some of the voodoo magic left by ZeBoxx2 in this thread (http://forums.cgsociety.org/showthread.php?f=98&t=705049) too.

The idea is to make a better subObject selector, that works during preview state started by commands with popup dialog.

Here is the code to check if a particular dialog is open. In the sample the "Extrude Polygons". It returns the handler if found, or undefined if not found.

(
hwndExtrudePolygons = windows.getChildHWND (windows.getDesktopHWND()) "Extrude Polygons"
format "hwndExtrudePolygons: %n" hwndExtrudePolygons
)
Returns:

hwndExtrudePolygons: #(11406358P, 65552P, 5308582P, "#32770", "Extrude Polygons") -- on my machine, if dialog is open
hwndExtrudePolygons: undefined -- if there's not that dialog
