Hi. I need some help with managing of the window(s).

For example:

1. Get/Set properties of window:
   • window's title
   • window's size (native)
   • window's position (native)
   • maximize/minimize window (native)
   • make fullscreen (native)
   • set/unset borderless (native)
   • set/unset topmost (native)
2. Handle events:
   • on size changed (native)
   • on position changed (native)
   • on window maximized/minimized (native)
   • on window closed
3. Multiwindows (native?):
   • make an additional window(s) and manage it
   • move window to specific display
4. Cursor:
   • hide cursor
   • set a custom cursor

In kha-api I found a several intresting classes and methods, but I can't find more detailed information about them:

• method System.init
• method System.initEx
• method System.notifyOnApplicationState
• method System.changeResolution
• method System.windowHeight
• method System.windowWidth
• SystemOptions
• Display
• Cursor
• WindowOptions
• WIndowModeOptions
• Mode
• Position

I can only get/set size of current (main) window's by System.windowHeight, System.windowWidth, System.changeResolution (by I'm no sure, that is the correct way).

Maybe somebody have an ideas/information how to use these and how to manage needed parameters?

(an similar topic on Kha's forum) Thanks.

For 3) you can take a look at the provided sample:

• https://github.com/Kode/Kha/tree/master/Tests/MultiWindow

To move a window to a specific display, use WindowOptions.targetDisplay. WindowOptions.Mode lets you set Windowed / Borderless / Fullscreen mode. This currently only works at initialization time.

@sh-dave Awesome! Many thanks. Also can I set window mode "Top Most"? I can't find this or similar property.

Currently not, but pull requests are always welcome :wink: Also, not all properties are actually implemented on all targets. I did most of the multiwindow code and only implemented what i actually needed at work (windows+opengl for development; linux for release later). So multiwindow probably won't work for like windows + directx. Also not implemented for macos at all.

@sh-dave Well, thank you for the update. For Linux your Multiwindow system also works fine! I opened enhancement issue for "Top Most" parameter. What about window's events? Is it supported?

Sorry, never tried it as i don't have a use case for that. The app i build only creates static sized, borderless windows and never lets the user change anything. But it might be a good idea to ask some questions in the irc (especially in the evening as more people are on), as i'm not sure how many ppl actually watch the issues here.

@sh-dave ok, Thanks for the help! I keep this issue to be opened

@r3d9u11 Are you trying to use native windows that can move anywhere or do you want to open up dialogs contained within the main Kha windows?

@primesoftware I'm trying to use several native windows, like in this sample

This is mostly done...

Noooo, not fully done yet.
