Is there a way to make certain event actions specific to left and right mouse clicks?

I'm creating a minesweeper gui, so when a square is left-clicked it will be uncovered, & when it's right-clicked it will be flagged.

I wasn't sure how to syntactically check for this & couldn't find it on the tut.

Thanks for the help!


I decided to give it a go, to try to create a simple Mine Sweeper application, one without a timer or reset (yet), but that is functional and uses both a GUI cell class and a non-GUI model class (it can't be copied and used in for intro to Java homework).

Edit 1: now has reset capability:

If you are using swing then

Is there a way to make certain event actions specific to left and right mouse clicks?

Implement a MouseListener no component. Then in implemented method you have a MouseEvent object which has a getButton() method which tells you which mouse is pressed.

Edit

OP has asked following question but now removed it.

Is this gui nested inside the other in an action event, when game_lost becomes true?

You can open a JDialog for this.
