Why can't I copy values ​​from an editable text field?

Question

I have a GUI where some values ​​are displayed in an editable text box . For some reason, I cannot copy these values ​​with the mouse. I can select the text, but no drop-down menu appears when I right-click on the selected text. I searched everywhere. What am I missing?

It is true that editable text fields do not by default invoke a context menu when you right-click, but there are several ways to get around this if you want to copy text to the clipboard:

• As Mikhail mentions in his comment, you can still select the text and press Ctrl+ Cto copy it to the clipboard.

• As Itamar mentions in his answer , you can create your own context menu for an editable text field using the UICONTEXTMENU and UIMENU functions . Here's an example implementation that uses the CLIPBOARD function to add an editable text string to the clipboard:

  hFigure = figure;                             %# Create a figure
  hEdit = uicontrol(hFigure,'Style','edit',...  %# Create an editable text box
                    'String','Enter your name here',...
                    'Position',[30 50 130 20]);
  hCMenu = uicontextmenu;                       %# Create a context menu
  uimenu(hCMenu,'Label','Copy',...              %# Create a menu item
         'Callback',@(hObject,eventData) clipboard('copy',get(hEdit,'String')));
  set(hEdit,'UIContextMenu',hCMenu);            %# Add context menu to control

• 'ButtonDownFcn' , , . m :

  function right_click_copy(hObject,eventData)
    hFigure = get(hObject,'Parent');               %# Get the parent object
    while ~strcmp(get(hFigure,'Type'),'figure')    %# Loop until it is a figure
      hFigure = get(hFigure,'Parent');             %# Keep getting the parents
    end
    if strcmp(get(hFigure,'SelectionType'),'alt')  %# Check for a right click
      clipboard('copy',get(hObject,'String'));     %# Copy the object string to
                                                   %#   the clipboard
    end
  end
  

  'SelectionType' , , , CLIPBOARD, . :

  hFigure = figure;                             %# Create a figure
  hEdit = uicontrol(hFigure,'Style','edit',...  %# Create an editable text box
                    'String','Enter your name here',...
                    'Position',[30 50 130 20],...
                    'ButtonDownFcn',@right_click_copy);

Answer 3

"Enable"?

(handles.editbox1, 'Enable', 'on');

(assuming you have a handle to this GUI object.)

This should make the editable field editable.
