  1. POmaking a QToolButton checked with a QMenu
    text
    copied!<p>I am designing a widget which has a grid of buttons. When clicked I want these buttons to present the user with 3 choices (ideally in a small drop down menu) that they can select from. When they select 1 of the 3 choices, I want that button to be selected (i.e., remain depressed). I want the QAction that is associated with each of the 3 choices to be able to know which button was clicked so that I can log which button in the grid was clicked. Each button in the grid needs to be exclusive, and when selected. The 3 choices presented are the same for all buttons.</p> <p>I first started with a QButtonGroup and QPushButtons in a QGridLayout. I was able to get the buttons to be exclusive as I wanted. When I changed the buttons from QPushButton to QToolButton, and added a drop down menu, two things happened:</p> <ul> <li>When they select an item from the menu, the button doesn't stay depressed like I want it to.</li> <li>I can't seem to see a way for the menu action to be informed about which button was selected, so I am unable to log which button is selected.</li> </ul> <p>Any thoughts on how I can achieve the functionality I am looking for?</p> <p>EDIT:</p> <p>A few clarifying points:</p> <ul> <li>Each button in the m x n grid represents a person.</li> <li>The drop down list on each button lets you select what action that person is currently doing.</li> <li>Only one person can be doing something at a time. Hence, only one button in the entire grid can be depressed at a time.</li> <li>The items in the button drop down menu should become checked when they are selected, and these items need to be exclusive, so if a button is clicked twice, the a new checked menu item in the drop down menu should uncheck the previous one. </li> <li>When an item in the button drop down menu is selected, the menu should go away and the button should appear depressed.</li> <li>I need to log the button (i.e., the row and column) that was clicked as well as the choice selected from the button drop down menu. So somehow menu item signal/slot needs to know about which button was clicked. However, QToolButton::setMenu() doesn't transfer ownership of the Menu to the QToolButton, so I'm not sure how to make the signals/slots in the QActions of the QMenu aware of which button was selected.</li> </ul>
