Gui.cs: UI Catalog - resize scrollbar issue

[daltskin]

Title bar not visible after window resize.

• Select Dialog screen
• Double click title bar to go full window
• Double click title bar to minimise window
• Select CTRL Q to go back

Note the vertical scrollbar has not gone to the top. I've noticed this on ListViews where the current selected item is preserved, causing the scrolling to make that selected item at the top of the screen

@daltskin I really preserved the current selected item but the behavior has to do with the WindowsDriverresize which maintain the current buffer after restore the window and the Driver.UpdateCursor will position the cursor to the current focused view forcing put it to the top because the buffer length is too big.
PS: On Linuxthis doesn't happen.

Dupe (same root cause) of #786.

[BDisp]

@tig I think this is a different issue. It has to do with the shrinkage of the window where using the WindowsDriveralways showing the vertical scroll bar after a full screen.

[tig]

Ok. Reopening. Thanks!

[BDisp]

Lol. I couldn't fix this with the buffer length but the workaround with the PR #796 solve this behavior too. Great.

[tig]

@daltskin will you please verify this is fixed. Thanks.

When leaving the scenario, the console occupies the entire length of the buffer, always without the vertical scroll bar.

Note the behavior for this will differ depending on which console is being used on Windows. I regularly try to test within:

• cmd.exe - The console host you get in the VS debugger and when you run cmd.exe
• Windows Terminal
• ConEmu - an open source console that's pretty darn good (but has bugs with console GUI apps)

Note the behavior for this will differ depending on which console is being used on Windows. I regularly try to test within:

* `cmd.exe` - The console host you get in the VS debugger and when you run `cmd.exe`

cmd.exe works great. With full mouse support.

* Windows Terminal

Windows Terminal works horrible very badly, leaving traces with many damaged layers. Mouse doesn't work. Except Ubuntuworks like asWSL 2.

* ConEmu - an open source console that's pretty darn good (but has bugs with console GUI apps)

ConEmu works badly too and blinking on resizing. Mouse doesn't work too.

On WSL 2 works very well. Better than cmd.exe on resizing. Mouse movements works with limitations with "export TERM=xterm-1002" or "export TERM=xterm-1003". See the differences here https://stackoverflow.com/questions/7462850/mouse-movement-events-in-ncurses. "export TERM=xterm-1006" doesn't support mouse movements any more now, it's a pity because it was the only one that supported the mouse on the entire screen of the application.

[daltskin]

Hmm.. it's still not quite right I'm afraid.

After resizing (from full-screen) the height of the window changes. Also notice that the status bar is now out of view when you return to the main menu.

[BDisp]

That behavior cannot be suppressed from WindowsDriverbecause of the buffer length that must be preserved otherwise it will throw an exception. In the Unix the Driverworks better in that case.

[daltskin]

Just tested in Ubuntu (WSL) and as you say, behaves much better :)
