GUIDE using CreateFcn to set TooltipString?

Hello everyone,

simple question, is it possible to change the TooltipString value of a static text in its CreateFcn? I want to display a formula, normally I would do it with following code:

set(handles.statictext,'TooltipString','somewhat longer formula here','Interpreter','latex')

Problem here is that the handles.statictext does not yet exist in its CreateFcn. If I only do:

set('TooltipString','somewhat longer formula here','Interpreter','latex')

it does not work either. Maybe there is a way to set the TooltipString interpreter to latex in the GUI Inspector in GUIDE?

Thanks for your help!

hObject is an input argument to the CreateFcn. Can't you just use that?

[Ingo Rück]

I have to correct myself, this is not working either. Changing the TooltipString itself with

set(hObject,'TooltipString','text')

is working to change the text, but I cant display a formula using latex this way. Error is: There is no Interpreter property on the UIControl class.

Yeah, I don't think you can do anything fancy with tooltips beyond just setting a string. Even edit boxes and text boxes themselves don't support advanced formatting without resorting to HTML or underlying java objects, as far as I am aware.

Not even static textboxes? Damn thats a bummer..

You can do it in OpenFcn! Is there any specific reason, why you do it in CreateFcn?

[Ingo Rück]

I would prefer if I could just set it in the Object Inspector in GUIDE. I can set the TooltipString there, but I cant make it interpret the string as latex.

I dont see another way to change the TooltipString right from the start.

When I try to change it in the OpenFcn I get the same error as above: There is no Interpreter property on the UIControl class.

Does this basically mean that it is impossible to use Latex to put a formula into the Tooltip string?

@Ingo: The error message is clear: There is no interpreter in uicontrol objects. Then you cannot display LaTeX directly in a tooltip string.
