Hi All,
I have created a GUI using guide and added a toggle button to the toolbar. I am trying to use this toggle button within another function to turn something on and off. My problem is I do not know how to properly call the handle and use it within the if statement. The code is listed below.
Details: There is an axes within the GUI that the user can draw points on. As the points are drawn they are numbered. I want to create a toggle button that allows the user to turn the numbering either on or off.
function createNode(x, y, hObject, handles)
nextN = size(handles.nodes,1)+1;
temp = plot(x, y, handles.pointStyle);
set(temp, 'HitTest', 'off');
label = yieldLabelText(nextN, handles.options.labeling);
temptext = text(double(x), double(y), ' ', 'VerticalAlignment','bottom', 'HorizontalAlignment','right');
set(temptext, 'HitTest', 'off', 'String',label,'FontSize',12,'Visible','on');
%Node number labels
%NOT SURE HOW TO SET THIS UP CORRECTLY*
if strcmp(get(handles.uitoggletool1,'Checked'),'on')
%Node number labels
set(temptext, 'HitTest', 'off', 'String',label,'Visible','off') ;
else
%Node number labels
set(temptext, 'HitTest', 'off', 'String',label,'FontSize',12);
end

Jan, I added some more details. Sorry about that. Basically, there is a bunch of points created by a user and I want to create a toggle button that allows them to turn the numbering on and off.

Christopher - use the Value property of the toggle button to determine if the toggle has been pressed or not. Try the following
if get(handles.uitoggletool1,'Value')==1
%Node number labels
set(temptext, 'HitTest', 'off', 'String',label,'Visible','off') ;
else
%Node number labels
set(temptext, 'HitTest', 'off', 'String',label,'FontSize',12);
end
If the Value property is one, then the toggle has been pressed. Though, from the above code, it isn't clear why you would create a text object just to hide it by setting its Visible property to off. Will you be keeping track of this handle, temptext, so that you can make it visible if the toggle is not pressed?
I think that much of the code to create the text control and set its properties can be reduced to
if get(handles.uitoggletool1,'Value')==1
visibleProp = 'off';
else
visibleProp = 'on';
end
temptext = text(double(x), double(y), ' ', 'VerticalAlignment','bottom', ...
'HorizontalAlignment', 'right', 'HitTest', 'off', ...
'String',label, 'FontSize',12, 'Visible', visibleProp);
Give the above a go and see what happens!

Glad it worked out, Christopher! As for resources, I use this forum or the File Exchange for ideas on how to program more complicated GUIs.
