I apologize in advance for not having more code to show, this is more of a conceptual question. I am working in Qt 4.7 and I have a QDialogButtonBox in my UI to which I need to add several custom buttons*. I set the buttons up like I normally would. For example, if I'm adding a Save button, I would create it like this:
QPushButton *myButton = new QPushButton(tr("Save"));
Usually I could just add this to my UI as is. However, I've found with the button box, it needs to have a "ButtonRole" attached, which are built-in to Qt. The only role that seems close to matching what I want is "ActionRole", but that's still sort of vague as to it's meaning when looking at it later in the code. I know theoretically any of the roles could be associated with this button, but it seems like really bad practice to me to attach an unrelated-named role like "RejectRole" or "HelpRole" to it just to make it work. My question is, how can I create a new role, something like "SaveRole", that I can use for this button? I tried putting a line like #define SaveRole (some int value) in my code and using that since the ButtonRoles are enumerators, but that gave me an error saying it couldn't convert the parameters. I know there's also NRoles in ButtonRole, and it seems like that can probably be used to create new Roles, but I've been searching for about a half hour and am finding it EXTREMELY difficult to find any information on how to use this. If anyone has suggestions it would be greatly appreciated. Thanks!
*For the record, I know how easy it would be to avoid this problem by using QPushButtons individually instead of a QDialogButtonBox, but my project head wants the button box used, so unfortunately I don't have that option.
EDIT: I forgot to mention before but it may be worth bringing up, this button box is pretty large, and all the built-in roles are already in use.

I'm writing an application using C++ and gtkmm. I made a Gtk stack in it. Now I want to add images instead of text on stackswitcher's buttons. I assume that it's possible because something like this is made in gtk3-demo:
Unfortunatelly the example is made using UI file and I want to do it without UI designer. For now I found this answer:
But it's not very helpful to me. The answer was to use stack.child_set_property but I checked gtkmm documentation for stack and there isn't anything like this for C++. The closest match was Gtk::Stack::child_property_name with adnotation that it returns A ChildPropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes. I suppose this may be the thing i'm looking for, but due to lack of examples I have no idea how to use it.
To sum up: Is anyone able to tell me how to set an image as StackSwitcher's label?
Ok, it seems I've found an answer. I'll post it if anyone needs it in the future:
To change Stack Switcher's text label into image I just needed to do that:
stack->child_property_icon_name(ChildName) = "Icon Name";
I have searched far and wide and cannot find anything online about my issue even though it seems rather trivial, and i feel like there's just something I'm missing, so I apologise if the answer is apparent.
However, when I use a QComboBox in Qt, When I click on it instead of dropping down like I want it to, it shows the popup with the current selected item as the origin. If that doesn't make sense this is what I am referring to:
It shows the popup starting at the current selected item where the button is. I just want it to drop downwards like any other normal combobox! How can i Achieve this? If i make it editable it drops down exactly how i want it, but i don't want it to be editable!
Does anyone know what's up?
Edit:
I am running Windows 10
i need to hide tabs from a existing project in QT, i don't want to delete the code because i have to set parameters on that code, the Application relay on that too. Seems like QT hasn't built-in hide(); function, i tried to edit stylesheet to make it smaller, but doesn't work too, i've looked on the internet and seems like this is a known issue. Does somebody have some tricks to avoid this?
Only thing i was able to come up with is:
ui->TabObject->setEnabled(false);
basically i disable objects in the tab to make them not usable by the user, but this is not a good thing for the whole UI.
Maybe by calling QTabWidget::removeTab(index) - this removes the tab from the QTabWidget, but does not delete the tab's QWidget.
I have a project where I'd like to have many wxPanel which are displayed or hide, depending the selection of the user. All panel are on the same position, only one is displayed at a time.
On a code side, there is no problem at all. Where it gets tricky, is how to manage this with wxSmith and keep a clear view while having many wxpanel at the sample location?
One way which is really not proper is to user the wxNotebook, and then when you start the soft delete all tabs and then show the needed panel.
I have look around to try to have the panel on a "other" wxSmith window and then load it, like a class but haven't find anything good.
I'm sure, as wxSmith is really a great tool that it must have a way to do this.
Thanks for your help!
See ya
"One way which is really not proper is to user the wxNotebook, and then when you start the soft delete all tabs and then show the needed panel."
Why not? I use that technique for AtomWeaver, and it works fine. The plus side is that you can design each page normally on a RAD GUI builder.
I've created a class called GUI_NotebookPageData that holds a pointer to a single notebook page. Create an array of these, holding info about all notebook pages.
Then, by index, or by name, get the info of the page you want to show/hide, and use wxNotebook's RemovePage()/InsertPage() methods.
This method is specially good for having several pages shown at the same time.
Actually it's possible to use external ressources with wxSmith, then it's very simple to manage the frames.
It create a derived class from wxPanel (or other window) on a new wxSmith window, easy to manage then just required to include it on the project.
Very quick question here. I was wondering if it is possible for me to reference individual tabs from a QTabWidget by number. This will save me a lot of time, as I am generating an unknown number of tabs during run-time. I could not find anything in the QT documentation, but I feel like this is a very basic feature that should be included. I am thinking something like this (not real code just an idea, I realize tabNumber() doesn't exist):
ui->tabArea->tabNumber(12);
If there isn't a public function, perhaps there's some other way? Please don't suggest referencing tabs by name because that is out of the question (potentially 100's of tabs), and I have already tried it.
If you want the tab with a certain index, use widget():
QWidget* tab = tabWidget->widget( index );
I think the setCurrentIndex() method is what you are looking for.
