Description xordevoreaux 2022-08-20 18:10:32 UTC

Description:
I increased my font size in Windows to see better (Windows Options, Ease of Access).

In the properties sidebar in LO, I cannot reach the bottom of the menu for the font list. Even arrowing down does not get me there.

Steps to Reproduce:
1. In Windows, Select go to Settings, Ease of Access
2. On the "Make text bigger" option, move the slider to the right by 1/8th.
3. Launch LO Draw
4. Expose the properties sidebar (View, Sidebar)
5. If you have a lot of typefaces, the bottom of the list will be cut off.

Actual Results:
Cannot traverse the entire typeface list

Expected Results:
The typeface combo box should scroll all the way down the list, not get tangled up with the windows task bar at the bottom.


Reproducible: Always


User Profile Reset: No

but this is not limited to Windows 'Ease of access' assistive technoloy. And not Sidebar only, it affects layout of all listboxes holding fonts with 'Show preview of fonts' enabled (the default).

Windows 'Ease of Access' is directing user to either Scale UI elements with fonts for the "Make text bigger", or to apply a simple scaling factor for "Make everything bigger"; both

The issue actually seems to be that is the listboxes holding Fonts are being scaled at a different amount to the rest of the LO UI. When UI is scaled the listboxes are not being resized to fit, and extend off the display.

Some relief is available by turning off the font previews (Tools -> Options -> View "Font lists" 'Show preview of fonts').

STR
1. set Windows -> System -> Display "Scale and layout" to 175%
allow desktop to scale
2. open Windows build (7.3.5 or master against 7.5)
3. open writer
4. from the 'Formatting' toolbar, use the selection triangle to open the listbox
note the listbox extends to bottom of display, and logically off the display
5. use cursor to scroll the highlighted font down
note at the bottom of the shown listbox that selection continues off the display
6. likewise openthe Sidebar properties deck and in the Character content panel
use the selection triangle to open the listbox and note it extends off display

The running off the display can be reduced by turning off the 'Show preview of fonts' from Tools -> Options -> View "Font Lists" entry. That reduces the total height of the listboxes

But even with font preview turned off the listboxes seem too high when Windows DE is in a scaled mode and exceed the bounds of the LibreOffice application frame. Dialogs are not affected; but listboxes attached to toolbar or in Sidebar or Notebook Bar are. Seems like something is needed to control their size--they already have scroll bar and thumb but they still get too tall.
