Implement command pattern in any way or anything similar or anything at all

Question

I have a controller class that listens to button presses from my button panel, and it also listens to mouse actions from another drawing panel.
When I press a button, it indicates some kind of drawing is going to happen in the drawing area. Only one action could be "active" at the same time. (To exemplify, put out square, put out circle, or whatever).
First I thought of using something similar to the command pattern. But when I press the button (here I wanted to create the command since then I know which one) I dont know yet which coordinates that are of interest. That would mean I would have to pass that data into the command�s execute() method, or create the command first now (right before it should execute)
Any suggestions of what could be a nice approach here are very welcome.
I know I am in that phase that I want to "patternize" a bit to much, but hey, at least you learn something and eventually you learn when not/how to use it more properly.

Answer 1

Maybe you could have a method that would return when the command needed to be excuted.
I dont get you fully there.
or could pass something else to the command that it could use determine when it needed to be executed?
I will however try to also send a bool which indicates whether it comes from a click or not. If that succeeds, I have managed to get all the commands to know by themselves when to do or not to do their stuff.
The only things that feels bad about that, is that only one command (for the moment at least) makes use of it. But I get rid of the bad smell ;-)
Add: Turned out that after all changes, most of the commands needed this variable too. Now everything feels good again ;)
