So I have a bejeweled like game that is created by taking a JPanel giving it a grid layout then putting buttons in the grid and assigning icons to the buttons. I'm trying to make the game restart when a certain key is pressed but I'm having several issues. Issue one is that when the game board is reset it does not call the main method and also the buttons rearrange but when the mouse hovers over a icon the icon reverts to the icon that was originally there. Another problem Im having is that the keylistener only takes input if no buttons have been pressed. Any help would be greatly appreciated!!!! Thanks
