Using Qt Sass

[goanpeca]

In order to clean up definition of styles (maybe make this package more generic), we could use https://github.com/spyder-ide/qtsass so that instead of hardcoding variables within the QSS, we could define SASS variables that would be used afterwards. By doing this, we could also "on the fly" generate custom stylesheets by changing these variables (either by simple line, search and replace) or by other method.

I am suggesting this now that we need to be able to access the color variables directly from python code.

Something like:

qdarkstyle/qss/_colors.scss

// Selection
$sel_light:  #148CD2;  // (selection/hover/active)
$sel_normal: #1464A0;  // (selected)
$sel_dark:   #14506E;  // (selected disabled)

// Foreground
$for_light:  #F0F0F0;  // (texts/labels)
$for_dark:   #787878;  // (disabled texts)

// Background
$bac_light:  #505F69;  // (unpressed)
$bac_normal: #32414B;  // (border, disabled, pressed, checked, toolbars, menus)
$bac_dark:   #19232D;  // (background)

qdarkstyle/qss/_styles.scss

/* QWidget ---------------------------------------------------------------- */

QWidget {
    background-color: $bac_dark;
    border: 0px solid $bac_normal;
    padding: 0px;
    color: $for_light;
    selection-background-color: $sel_normal;
    selection-color: $for_light;


    &:disabled {
        background-color: $bac_dark;
        color: $for_dark;
        selection-background-color: $sel_dark;
        selection-color: $for_dark;
    }

    &:item {

        &:selected {
            background-color: $sel_normal;
        }

        &:hover {
            background-color: $sel_light;
            color: $bac_normal;
        }
    }
}
...

And then compile this file:

qdarkstyle/qss/main.scss

@import 'colors';
@import 'styles';

Hi @goanpeca, yeah, I was looking into this SASS, and this is much better. This is planned to integrate the v3.0. Unfortunately, I'm a little busy with other projects right now, so some delay is predicted.

I already started working on this. I can submit a PR

Perfect! Thank you!
