Zeal looks too small on Linux

[animeshkrishnabulusu]

Hello! Zeal looks too small on Linux. I can Ctrl+MouseWheelZoom on the docs, but rest of the app looks too small.

I am a long time Zeal user. This is the first time I tried it on a Linux. One of the things I tried is to use lxappearance and set the Default Font to bigger sizes. Other programs respond to this change, but not Zeal.

Details:

• OS: Debian
• No DE, just a tiling window manager.
• Zeal v0.6.2-dev
• Resolution: 1920x1080

This may be a problem with the Qt appearance settings, and the LXAppearance application is intended to change GTK (formerly Gtk+) appearance settings, specifically targeting Gtk+2.0 and Gtk+3.0 versions. Most installations of the Zeal documentation browser on Linux systems are based on Qt, so changing Gtk+2.0/Gtk+3.0 settings may have no bearing on the Qt appearance and interface settings.

I think this small interface should be fixed with Zeal v0.7 built against Qt 6. Alternatively, this is caused by misconfiguration of the Qt platform plugin, so Qt apps don't look native in your DE.

Great news! Hope this fixes it. 🤞

@anmsh were you able to test Qt 6 based Zeal v0.7.x?

[animeshkrishnabulusu]

The latest version as per my distro is 0.6+. I will try with the source install and report back.

I did try the source install method and had some trouble with the install. Most likely something to do with having both Qt 5 and Qt 6. I need this sooner. So I will report back sooner.

I can install the zeal version v0.7.2-dev.23+1067eae Qt5 version after installing the following three packages libqt5webchannel5-dev, qtwebengine5-dev, libqt5x11extras5-dev.

I will have to try with a fresh Qt6 install and report back.

Edit: included zeal version

Any news 2 years later? I think a number of these problems got addressed, but probably not all of them.

[animeshkrishnabulusu]

I think it was built based on qt6. As you can see the tree element, title, menu all look much smaller, with no way to control the size. The docsets are excellent display wise.

Let me know if I should try anything. Thank you.

Try setting QT_SCALE_FACTOR=2. I also I suggest updating to 0.8.1 to get all the fixes I made recently.
