Hello,
is it possible to change or remove the border in the working area of a CControl?
Please see the screenshot. There is a raised bevel border around the empty working area and around the left docks. That is with the flat theme.
What I really find strange is that there is BORDER_MODIFIER in DockTheme,
but neither FlatTheme nor BasicTheme are set a BevelBorder anywhere. Also EclipseTheme is not set any border.
So where is this border set? It must be in the theme, because the EclipseTheme does not show this border.
It is possible. The border is actually created by objects of type “DockableDisplayer”, and these objects depend on the theme.
Run the example below, it will disable the borders.

import javax.swing.border.Border;
import bibliothek.gui.Dockable;
import bibliothek.gui.dock.common.CControl;
import bibliothek.gui.dock.common.CLocation;

themeManager.setBorderModifierBridge( DisplayerDockBorder.KIND, new NoBorderModifierBridge() );
/* and we just add some content to the JFrame */
frame.add( control.getContentArea() );

DisplayerDockBorder displayerDockBorder = (DisplayerDockBorder)uiValue;
/* "uiValue" represents the request for a property, "value" is the default value, "id" is the
* the name of the property.
* "uiValue" tells us for which Dockable the property is requested... */
Dockable dockable = displayerDockBorder.getDisplayer().getDockable();
if( dockable instanceof CommonDockable ){
CDockable cdockable = ((CommonDockable)dockable).getDockable();
if( cdockable.asStation() instanceof CWorkingArea ){
/* ... and if the property is requested for a CWorkingArea, we set the "NoBorderModifier" */
value = new NoBorderModifier();
}
}
uiValue.set( value );
}
}
/* The "NoBorderModifier" replaces any border with "null" */
private static class NoBorderModifier implements BorderModifier{
@Override

return null;
}

}
yes thank you that works. But what about the left docks?
Your code is removing the border around the working area, but how about the border around the docks on the left?
