gui trigger event on variable change
in [Matlab]
|
From: Marco on 20 Jul 2010 03:42 i'm creating a gui that, given a time series and a time axis, displays the data and gives the user some controls on it. so its prototype will be something like fig_handle=GUI_displayTS(time_series, time_axis) since i want to be able to change the data displayed without completely redrawing the interface i'd like to be able, once the GUI is created, to load new data into it and then trigger the redrawing and its general updating. loading new data is quite easy (i will load the data into the "Userdata" of the figure from the invoking function), but i can't figure out how to configure the system to trigger the update when the value of userdata is changed. can anyone suggest me a way to do it?

From: Marco on 20 Jul 2010 08:40 well..my problem is a bit more complicated than that: i don't simply have to refresh the plots but i need to launch functions to update a series of ancillary informations and perform other actions (all inclueded in the gui). that's why i think a solution might be linking an event to the update of the variable, so i can manage on my own the actions to perform... but maybe there's a smarter solution i can't think of... thanks anyway for the suggestion!

Have whatever callback function loads the data also call a function that updates the GUI? -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ To contact Technical Support use the Contact Us link on http://www.mathworks.com

it would be nice, wouldn't it? ;) the problem is that the load of the new data must be done in the invoking function, not in the gui itself!
