I'm using Qt with C++, and I want to make a button that keeps looking pushed down after it is pushed and released. I'm currently making buttons on a QToolBar and doing something like toolBar->addAction (icon, tr("Text"));. This makes buttons on the toolbar that display the QIcon named icon and display "Text" on hover-over. They also look pushed down as the user is pushing them, but stop looking pushed down when they are released (as is reasonable for most uses of buttons). I need something different, however: I would simply like the buttons to remain looking pushed down after they are released, perhaps until they are clicked again. It would be best if I could just call some function on a button or on the toolbar that could give me the capacity to control whether a button will look pushed down or not pushed down when it is displayed. That way I could just control this aspect of button appearance programmatically.
What's the easiest way to do this in Qt? I've seen fancy ways of doing it involving borders and very complicated setups, but I was wondering whether there might be an easy way to do it.
Add QPushButton to the toolbar using addWidget and then make the button checkable.

So I am having this issue with using Google VR reticle where I cannot click a button. I have an image attached showing the heirarchy and the PlayButton is what I am trying to click. The Canvas has a Graphic Raycaster, the button has an Event Trigger that calls the method to navigate to the next scene. The UpScrollPanel, and DownScrollPanel work just fine. The EventSystem has the Gaze Input Module, as well as Event System, and Touch Input Module.
Any ideas on how to get this working? I have watched a few videos from NurFACEGAMES and while they helped a little, I haven't gotten the click to work yet.
Oh, and I am using Unity 5.3.4f
Sometimes things can get in the way of the button, make sure that no other UI elements overlap it, for example text borders (which are actually larger than they appear). You can also fix this by moving the button up the hierarchy among its siblings, I believe the first child is top.
Also try moving the button up the hierarchy if possible, sometimes UI having certain parents makes them not work
The canvas object should have a graphic raycaster
I found the issue to be unrelated to anything I thought it was. The menu I was using is a prefab I also use in another view that isn't VR. The scrollrect was loading that prefab, instead of the modified one I was using in the VR menu, and therefore the triggers I had added to the button were no being used when the app loaded.
I saw once someone making the GUI in QT and he had something I have never seen until now: They looked like big buttons one after another and when you clicked on them, the buttons below were going down, making space for the dialog or tab. It was like, if you click on the button "Draw", suddenly below the button a tab or a dialog or ??? appeared with all the GUI components (radio buttons, listboxes, ...) that you need for draw. When you clicked on another button, this GUI disappeared to make space for another GUI. Does anybody know what it is?
Qt does support tabs.
They are actually different widgets you can switch from in the same window.
Here you can find an example on how to use then: http://qt-project.org/doc/qt-4.8/declarative-ui-components-tabwidget.html
Inside a tab it's just like a normal widget.
How to Remove Toolbar from QToolBox in Qt?
Normal Toolbox looks like this:
I want to remove this button written with Page 1. Something like this :
I'm not sure if this makes much sense, since those buttons are needed for the functionality of the QToolBox. If you want a stack of widgets for which you can manually control if they are shown or not, then QStackedWidget provides similar functionality without displaying any elements of its own.
edit: No, as the QToolBox it doesn't come with a scrollbar. But since you 'fill' it with widgets of your own, which then are displayed with setCurrentWidget, you can use for example QScrollArea and placing your own widgets inside it.
I am trying to use QSystemTrayIcon for my application and i am facing some problems.
It is the first time i use qt so i am not really used to it.
I followed this tutorial to make a system tray icon but i fail to customize it.
I want to have a button show/hide and not 3 show, hide, restore. These actions are really confusing for a newbie and i dont know what to do and what to connect.
I tried some things but with no luck.
Also when the system tray menu appears if you click somewhere else, the menu stays open.
Any way to solve this thing too?
If you want to remove one of the menu items, modify the createTrayIcon function so that it only adds the actions you need (and clean up the unused members once you get it to work). It's that simple.
If you want a single menu item or button to toggle between visible and hidden, you'll need to create a custom slot that calls show() or hide() (or setVisible(bool)) depending on whether the widget is hidden or not (use isVisible() for that for example). Then connect your action to that slot.
Read the Signals and Slots documentation and examples for information about how to create a new slot.
I need on my form ordinary widgets (e.g. buttons) do not react on mouse clicks but NOT to be disabled (it change look to grayed one -- not good).
I wonder is there some neat small hack for this?
You could stick in an event filter and filter out the mouse events before passing the remaining events on for processing, but I'm not sure that not giving the user a visual clue that certain elements are effectively disabled is such a good idea.
You could try using style sheets to control how the disabled mode of the buttons in your form get styled. Unfortunately I'm not sure exactly how to do that but you could have a look at the style sheet docs to get you started.
