Custom color for selected text in TextEdit

[Wilovy09]

I'll put it here since it won't let me enter Mattermost and I didn't find any discord server for the Slint community.

• Is there any way to change the color of the selected text inside a TextEdit?

Like the example below (I know they are different things, but it's a good way to make myself understood).

The TextEdit cannot be configured as it takes its color from the Palette
What can be configured is the raw TextInput element: https://docs.slint.dev/latest/docs/slint/reference/keyboard-input/textinput
It has selection-background-color and selection-foreground-color properties.

@ogoffart And wouldn't it be nice if this could be included in the TextEdit component itself? without having to make a component using the TextEditBase? since it is something simple and doesn't require much maintenance. I have the code changes already done.

import { TextEdit } from "std-widgets.slint";
export component AppWindow inherits Window {
    width: 800px;
    height: 600px;
    title: "Test Component Example";
    VerticalLayout {
        width: 100%;
        height: 100%;
        padding: 10px;
        spacing: 10px;
        TextEdit {
            text: "Custom selection colors text.";
            selection-background-color: #3fbc3b;
            selection-foreground-color: #000000;
        }

        TextEdit {
            text: "Default colors for selection";
        }
    }
}

I don't want it to feel as a lack of respect, I don't know if this breaks with Slint's philosophy, I propose this more than anything because I think it is very unnecessary to have to create components from scratch just for this feature (in my opinion).

Right now, the widgets cannot be themed easily. They are meant to look native.
This is something we may want to revisit. See #4372
