Thread Subject: How to insert a transparent pushbutton after GUI starts?

Hello,

I am right now trying to write a GUI that will:
1) find particles on an image and place a box around each of them
2) after it finds the particles, the user needs to be able to click within the box surrounding a particle to perform more calculations on that specific area

The only way I can think of doing something like this is to insert a transparent pushbotton on top of the axes displaying the image... is this possible? Is there a better way?

Thanks,
Adrian (arandall@mit.edu)

I'd suggest using the function GINPUT where the user can specifiy a coordinate with the mouse. the function returns the [x y] coordinates and you can directly work with them.

You can specify the position of the pushbuttons (or any other GUI object) [X Y Length Width] using the 'position' handle of whatever object you're using.

As for the other requirements I'm not sure.
