hide/show several gui objects at once
Hey.

I'm trying to create a mode in my game that needs all current Gui objects hidden and some other shown. And being able to switch back to the previous mode.

The solution I came up first was a function that hides all the current gui objects and keeps track of which ones where shown before. This way I can show them again afterwards. Drawback is that I have to update this function every time I add a gui object.

Another solution would be having a second EE::GUI object, add the windows for the special mode to this gui and switch between these two in update and draw mode. I tried this but it seems I missed something, because my second gui didn't show.

I also saw that objects are added to the "current desktop" if added to the Gui with +=. So there's more than one desktop? And can I somehow switch between several desktops? I can't find any code for that.

Any ideas?

Regards,

yvan

currently there is no api to switch between desktops

you can use region1, region2 with transparent backgrounds, and add objects to them.

however I recommend simply calling hide/show for all objects separately

RE: hide/show several gui objects at once
I am facing the same issue with some of my complex gui windows that have many controls and can be in different "states." I have found it useful to logically group the controls into transparent regions. Then whenever the gui window needs to change state, it is just a matter of adjusting the visibility of a few regions, rather than dozens of individual controls. In my case, the gui window state can change from frame to frame, so I need to check every frame and adjust region visibility. That is why I was asking if it was ok to do this every frame in a previous thread, performance wise, as I wasn't sure if changing a region's visibility was an expensive operation.

Thanks, fatcoder. I came up with another idea. Wrote it down in the code snippets forum, as usual :-)
