MATLAB: Set(h, ‘BackgroundColor’, ‘Black’) – Not working in Linux

backgroundcolorcoloredittextset

Hi,

I'm making a gui with several edittexts. I would like these to have a black background and white text. First I tried to simply set this in the GUI editor (Guide), but it didn't seem to work, since they start out being disabled. Then i tried adding a function which adjust them, when they are activated. The code goes like this:

set(handles.editXoffset, 'BackgroundColor', 'Black',...
                         'ForegroundColor', 'White');

This works fine on windows machines, but on Linux, both background color and font color is shown as white. Looking in the properties, using:

get(hObject)

…in the edittexts callback, it shows this:

BackgroundColor = [0 0 0]
...
ForegroundColor = [1 1 1]
...

So it seems to be getting what I tell it, but it just don't show. What am I doing wrong here?

See: Answers: controlling-background-color-of-selected-uicontrol.

The operating system can override the specified colors, and obviously it does under your Linux platform. Which Matlab and OS version are you using?

fatih - what is the full error message that you are observing? Are you using GUIDE, App Designer, or have you created your GUI programmatically? If using GUIDE, then you will need to use the handles structure to reference your edit1 control

set(handles.edit1, 'BackgroundColor', [0 0 1]);

The background color can be changed. Programmatically this can be done as

hEditControl = uicontrol('Style','edit');
set(hEditControl, 'BackgroundColor', [0 0 1]);

The selected pop-up gets the different color as long as the UICONTROL has the focus. Although Matlab's documentation claims that "figure(gcf)" gives the focus to the figure, this does not work from at least Matlab 5.3 to 2009a. Therefore I usually insert a call to a function named "FocusToFig" in the UICONTROL's callback function:

function FocusToFig(ObjH, EventData)  %#ok<INUSD>
% Move focus to figure
% FocusToFig(ObjH, [DummyEventData])
% INPUT:
%   ObjH: Handle of a graphics object. It is tried to move the focus to the
%         parent figure and making it the CurrentFigure of the root object.
%   DummyEventData: The 2nd input is optional and ignored.
%
% Tested: Matlab 6.5, 7.7, 7.8, WinXP
% Author: Jan Simon, Heidelberg, (C) 2009-2011
if any(ishandle(ObjH))   % Catch no handle and empty ObjH
   FigH = ancestor(ObjH, 'figure');
   if strcmpi(get(ObjH, 'Type'), 'uicontrol')
      set(ObjH, 'enable', 'off');
      drawnow;
      set(ObjH, 'enable', 'on');
   end
     % Methods according to the documentation (does not move the focus for
     % keyboard events under Matlab 5.3, 6.5, 2008b, 2009a):
     figure(FigH);
     set(0, 'CurrentFigure', FigH);
  end
return;

This moves the keyboard focus also to the figure, such that the KeyPressFcn is called again.
