Then we can create the MainWindow::whenButtonIsClicked() in our. In the constructor of your MainWindow AFTER the ui->setupUI(this) which initialize the ui. Now add: connect(ui->pushButton, SIGNAL(clicked(bool)), this, SLOT(whenButtonIsClicked()))
QT CREATOR C 11 CODE
So let's go back to our code and go to mainwindow.cpp We can do it with the method name connect.
The first is to connect the button with a method we created. And if you resize your window, the label and button are resizing too.īut our button is still doing nothing. Here you can see your application with the label and the button. So now Move (with drag and drop again) your label and button in the layout. Now you should see that your objects a vertically aligned in your window. So now right click on the main window, anywhere except on the label and button. So drag and drop a vertical layout from the object list at the left. By the way, if you resize your main window, you can see that the object are keeping their place. Huh? Why my label and button are like that when I run ? It's because there is no layout in our central object. Now if you save and run (better click on the edit button then save again to be sure your modifications has been saved), you get: Or you can see at the bottom right the properties of the object you are now and find the text property. Then search the Label, and do the same (you have a filter at the top left where you can write the object you are looking for).īy double clicking of the object, you can change the text on them. Click on the Push Button and drop it in the window. You can click on one and drag&drop the objects. On the left, there is the list of the items. But once you get used to it, it really great. Here Qt Designer ! Seems quite complicated. So now you should see: (if not and you see some xml file, click on the Design button at the left) if you run it now by clicking on Build->Run or ctrl+R (by default) you will see an empty window. Again if it's only for tests, you don't need to change them. The last step can be to choose a subproject of this project and to add a version control such as git and svn. If you are learning or testing Qt, you don't really need to change them. Then you can choose the name of your main window class, the inherited class, the name of the file corresponding to your main window class.
QT CREATOR C 11 INSTALL
If you don't have any compiler, you can install one. If you don't have any kit, QtCreator will create a kit with your Qt version and the main compiler of your computer. Next, you can choose the kits you will be using. Then you can choose the name and path of your project : Then choose the Projects->Application->Qt Widgets Application To create a new application click on File->New File or Project:
QT CREATOR C 11 HOW TO
In this example, we will see how to create a simple Qt application which manage a button and write text. QtCreator is, at the moment, the best tool to create a Qt application. Basic application with QtCreator and QtDesigner
