one panel over all windows

[Andy]

Hi, is it possible to show the vizinfo panel in front of all subwindows?

I have some subwindows and if I open the panel I can see it in all subwindows. Also the sub-windows mask the panel of the MainWindow.

A vizdlg panel is shown only on the MainWindow but it is mask by the subwindows.

My idea is to create a new subwindow, transparent without content only with the panel and then bring it in the front of all windows. Is it possible?

Thanks

Your idea will work. The following code adds the info box only to a transparent window on top:

import viz
viz.go()

gallery = viz.add('gallery.ive')

import vizinfo
info = vizinfo.add('Info box in transparent window')
info.translate(0.05,0.95)
info.alignment(vizinfo.UPPER_LEFT)

#don't add info box to MainWindow
viz.MainWindow.visible(0,viz.SCREEN)

#add a subwindow
subWindow = viz.addWindow()
subWindow.setPosition([0,1])
#dont' add info box here
subWindow.visible(0,viz.SCREEN)

#add a clearWindow that the info box appears in
clearWindow = viz.addWindow()
clearWindow.setClearMask(viz.GL_STENCIL_BUFFER_BIT)
clearWindow.setPosition([0,1])
clearWindow.setSize([1,1])

Hi, thanks for your answer but there is a problem, the "clearWindow" isn't transparent.
If I change the size or the position of this window (so that it doesn't overlap) I still see the environment in this "transparent" windows. Is this a bug or doesn't work the GL_STENCIL_BUFFER_BIT on my hardware?

The previous sample is incorrect. The following sample should do what you want:

import viz
viz.go()

gallery = viz.add('gallery.ive')

#add a subwindow
subWindow = viz.addWindow()
subWindow.setPosition([0,1])

#create info box in custom scene
import vizinfo
info = vizinfo.add('Info box in transparent window')
info.translate(0.05,0.95)
info.alignment(vizinfo.UPPER_LEFT)
info_scene = viz.addScene()
info._group.parent(viz.SCREEN,info_scene)

#add a clearWindow that displays the custom scene
clearWindow = viz.addWindow(view=viz.addView(scene=info_scene))
clearWindow.setClearMask(0)
clearWindow.setPosition([0,1])
clearWindow.setSize([1,1])

I have a similar problem. I want to run the main window on the 2nd screen of an extended desktop and keep the vizdlg.Panel() that I have already created on monitor 1. How can I place one item on each screen? thanks

You can change the position and size of each subwindow object so that it only appears on a specific monitor. Then you can add the panel to the desired subwindow.
