Can't change text colour on linearbar sllider

General JUCE discussion

Hi!

I want to change the text colour on a linear bar slider. I have overrided the drawLinearSlider method and tried to set these colours in my LookAndFeel constructor:

        setColour (Label::textColourId, Colours::black);
        setColour (Label::textWhenEditingColourId, Colours::white);
        setColour (Label::backgroundWhenEditingColourId, Colours::black);
        setColour (Label::outlineWhenEditingColourId, Colours::black);
        setColour (Slider::thumbColourId, Colours::white);
        setColour (Slider::textBoxTextColourId, Colours::black);
        setColour (Slider::textBoxBackgroundColourId, Colours::white);
        setColour (Slider::trackColourId, Colours::grey);

But nothing works. The text is still white:

Any ideas?

Thanks,

You may customize those colours by overriding drawLabel() method.
Perhaps there is also a way to set it with those ColourIds. However, I am not familiar with them.

Just recently I also noticed similar anomalies in the text box of the linear sliders.
windows10, juce 8 branch.
new LookAndFeel settings work on the slider part, no effect on the text box.

the LookAndFeel does not update the new settings until you refresh it:

auto& laf = myGuiComponent.getLookAndFeel();

    laf.setColour(Slider::ColourIds::backgroundColourId, Colours::red);
    laf.setColour(Slider::trackColourId, Colours::green);               
    laf.setColour(Slider::thumbColourId, Colours::purple);             

    laf.setColour(Slider::ColourIds::textBoxOutlineColourId, Colours::white);
    laf.setColour(Slider::textBoxBackgroundColourId, Colours::purple);
    laf.setColour(Slider::textBoxTextColourId, Colours::black);
    laf.setColour(Slider::textBoxHighlightColourId, Colours::red);

// refresh the LookAndFeel
myGuiComponent.setLookAndFeel(&laf);

same with:

auto& laf = juce::LookAndFeel::getDefaultLookAndFeel();

// ... your colors here

juce::LookAndFeel::setDefaultLookAndFeel(&laf);

Thanks for the help! I added this to my LookAndFeel class:

LookAndFeel() {
        using namespace juce;
        
        auto& lnf = getDefaultLookAndFeel();
        lnf.setColour (Label::textColourId, Colours::black);
        lnf.setColour (Label::textWhenEditingColourId, Colours::white);
        lnf.setColour (Label::backgroundWhenEditingColourId, Colours::black);
        lnf.setColour (Label::outlineWhenEditingColourId, Colours::black);
        lnf.setColour (Slider::thumbColourId, Colours::white);
        lnf.setColour (Slider::textBoxTextColourId, Colours::black);
        lnf.setColour (Slider::textBoxBackgroundColourId, Colours::white);
        lnf.setColour (Slider::trackColourId, Colours::grey);
    }

That gives me the correct colors:
