HxCFloppyEmulator font size on Linux

[frank128]

I want to use the HxCFloppyEmulator under Linux. I can start the HxCFloppyEmulator as a FlatPak package directly under Linux, but also as a Windows 64Bit EXE file under Wine. Unfortunately, I can not change the font size with either option, so that the app is practically unusable on modern big 4K screens.

With Wine, you can normally easy scale the screen resolution of a Windows App running on Wine via winecfg (dpi parameter). HxCFloppyEmulator is the first Windows app where this obviously doesn't work. But even under Linux, the Flatpak app HxCFloppyEmulator cannot be persuaded to change the font size via Flatseal (GDK_DPI_SCALE,GDK_SCALE).

What do you have to consider?

Which font/text are you talking about ?

[frank128]

Users with large screens (above 27 inch) usually scale their desktop (independent from text or grafic), otherwise they cannot read the menus and texts due to the tiny size. Some can be enlarged in Linux using the Windows Manager (Monitor Settings) , or even offer options to adjust the text size of the application.

ok but which font/text are you talking about ? The font on the main window or the track viewer ?

If you link the software against FLTK 1.4.x you can zoom all windows with the CTRL + '+' and CTRL + '0' keys.

you can build the software with the FLTK 1.4.x with the "FLTK1_4=1" flag :

make FLTK1_4=1

The problem here is the attempt to download a snapshot version of the component fltk (Fast Light Toolkit), which was included with make FLTK1_4=1 and apparently no longer exists.

https://www.fltk.org/pub/fltk/snapshots ... 5e9.tar.gz

https://www.fltk.org/software.php

https://www.fltk.org/pub/fltk/snapshots ... 553.tar.gz

is the current snapshot of the not released development version 1.4.x.

I got it but with a hack in

HxCFloppyEmulator/HxCFloppyEmulator_software/sources/thirdpartylibs/fltk/prepare_fltk.sh

Code: Select all

# diff prepare_fltk.sh prepare_fltk.sh.ORG
4,6c4,5
< export DOWNLOADURL=https://www.fltk.org/pub/fltk/snapshots/fltk-1.4.x-20240906-d8eb4553.tar.gz

> fi

and a symbolic link (fltk-1.x.x is also hardcoded in another place that I could not found)

lrwxrwxrwx 1 root root 28 Sep 11 08:45 fltk-1.x.x -> fltk-1.4.x-20240906-d8eb4553

The good message is, it fixes the font size issue.
