Hi.

in juce\_TextEditor.cpp there’s the following line (setOpaque):

`
void TextEditor::colourChanged()
{
    setOpaque (findColour (backgroundColourId).isOpaque());
    repaint();
}`

What if I have other colours (outlineColourId, focusedOutlineColourId, etc…) which are transparent but the background colour itself is solid?  
In that case, if I don’t specifically set the opacity to false, changing the background colour afterwards to something solid will reset the opacity to true, resulting in a weird TextEditor…

Currently I commented this line out…  
Is there a way to overcome this issue instead of setting opacity to false after each background change?

Thanks.

I don’t understand the problem… If the background colour is fully opaque, then the component should be marked as opaque. Why would any of the other colours make any difference?
