6413	Windows Qt6 editable combobox font problematic	Tony Schaefer	Eric Pettersen	"{{{
The following bug report has been submitted:
Platform:        Windows-10-10.0.19044
ChimeraX Version: 1.4.dev202203180014 (2022-03-18 00:14:36 UTC)
Description
Command line problem with Qt6 on Windows 10 - the font is different than Qt5, so descenders get cut off on the command line. This is particularly noticable with the letter g. Qt6 is using the Win10 default (Segoe UI), whereas Qt5 used Tahoma (MS Shell Dlg 2). Segoe UI has longer descenders. I've attached an image showing some text on the command line in both Qt5 and Qt6. 

Adjusting the size of the command line does fix this, but I think the default size ought to look good. There are some stackoverflow posts looking for solutions to a similar issue with CSS. Perhaps some of those solutions will work in ""QSS"". However, QSS can suck to work with as it sometimes changes a lot of things. Going back to the old font would also probably work, but maybe Microsoft changed to Segoe UI for a good reason. I have a script that changes the font size of the command line (makes it easier to show commands to other people). Running it to set the font size to 9 (appears to be the default size) fixes the issue for me. I'll include it here in case it helps:

```
from chimerax.cmd_line.tool import CommandLine

from Qt.QtGui import QFont, QFontMetrics

# change to control the size
new_size = 9

# get the command line tool object
cmd_line = CommandLine.get_singleton(session)

# make a copy of the command line's current font, but with
# larger/smaller text
new_font = QFont(cmd_line.tool_window.ui_area.font())
new_font.setPointSize(new_size)
cmd_line.tool_window.ui_area.setFont(new_font)

# need to adjust the size of the text box to be appropriate
# for the larger/smaller font
metrics = QFontMetrics(new_font)
min_height = int(1.25 * metrics.boundingRect(""Qy"").height() + 5)
cmd_line.text.setMinimumHeight(min_height)
```
