Hello

How can I change the EclipseTabTransmitter?

I wanted to change the foreground color of the tabs with

dockable.getColors().setColor(
    ColorMap.COLOR_KEY_TAB_FOREGROUND,
    Color.WHITE
);
dockable.getColors().setColor(
    ColorMap.COLOR_KEY_TAB_FOREGROUND_FOCUSED,
    Color.BLACK
);

But the foreground color of the non focused tab is not white but gray. Seems that EclipseTabTransmitter is mixing color’s and not using the color I set (see EclipseTabTransmitter.convertSelected and EclipseTabTransmitter.convertFocused ).
How can I replace EclipseTabTransmitter so I get the foreground color I want?

Btw. ist that a typo in EclipseTabTransmitter when it says “stack.tab.tob…” instead of “stack.tab.top…”?

Thanks in advance and kind regards

Uh, the “tob” will be replaced in the next release… :o

Since the EclipseTheme normally uses gradients it mixes colors a bit. Just using one color can look very ugly. But you can easily create your own EclipseTheme which does mix the colors differently (or not at all). The code snippet below should give you all the information you need to start.
