This will ensure that all your widgets will be displayed and resized properly when the form is previewed or used in an application. After you place all the widgets on your form, you need to place them in a coherent layout. Qt Designer has a clear and user-friendly interface that allows you to create any kind of GUI by dragging widget onto an empty form. Qt Designer's main interface looks as follows. It allows you to add different kind of widgets to create your GUIs using on-screen forms and a drag-and-drop based interface. With Qt Designer, you can create windows, dialogs, and forms. Qt Designer is the Qt tool for designing and creating graphical user interfaces (GUI) for desktop applications. In this tutorial, you'll learn how to use Qt's layouts with Qt Designer to build complex GUIs for your applications.Īdditionally, we'll create a dialog example using several widgets with a coherent layout to reinforce your knowledge and put everything together into a fully functional dialog just like you would create in a real-world application. To lay out the widget in a form, you can create everything in code, or you can create your layout with Qt Designer. Fortunately, Qt offers a set of layout managers that simplify the process of widget positioning and will allow you to easily create any kind of layout. When laying out your PyQt5 GUIs it can be quite a tricky task to place every widget in the right position on your forms.
