Add support for setting a custom Qt stylesheet

[ghost]

I would like to request a theme editor to make and edit existing themes.

Seems out of scope for this tool.

If you make themes, you also must have a way to let users create them.

[bjorn]

I'm not sure what you mean. The user can pick a style, its color and a selection color. It isn't much of a theme, though I do think it would be nice to add some presets.

You are talking about these settings, right?

[ghost]

like this: https://github.com/aseprite/themes

Then some very simple settings in this tab (color for this thing in the program, ...) and "export to theme file" (and 'load theme")
in this way the communicty can make themes and distribute them

i would like to have an all black theme and in this way we can create it.

Hmm, it is possible to use a stylesheet to customize the appearance of Tiled, for example:

This way you can customize a great deal, though I'm not sure if it would suffice. Since this is a Qt feature, you could probably already find existing Qt stylesheets that you could use on Tiled. If there are, it would indeed be nice to document this feature in the manual and to make user themes discoverable somehow.

yes please please please! :)

• You should make an option in the "theme" tabpage for loading a QT stylesheet file
• and write it in the manual + explanation how to edit it

There is no work to do for you, just add something to make tiled run with the stylesheet

• enable or disable the option and file chooser to choose the stylesheet
• maybe a list in tiled's UI that displays all the *.qss files (maybe make a subfolder "stylesheet" in which you need to put them) by reading the file name of the qss file
• https://qss-stock.devsecstudio.com/documentation.php

I found a website https://qss-stock.devsecstudio.com/templates.php
and they all work! For me personally, it's good enough. It looks good and I don't more. Also all widgets are changed in the chosen color. I'm already using it!!! :)

Can you open the issue again? You can put the stylesheets on github. I see they are MIT license. I have change the issue's title!

You can re-open this please?
It's very interesting

[ghost]

[bjorn]

Yes. I think we could model this setting after the "Use custom stylesheet" option in Quassel IRC:
