How to Create Qt Project And Compile It

The beginners is usually compare about Qt programming with their currently programming environment being used. For example they compare to Visual Basic 6.0, some of the easiest GUI programming in Windows environment. Because there is a wide different between VB6.0 and Qt, not only in language but also how to create the project, this section will show you step by step creating and compiling project successfully.

In this part, I will show you the simple thing how to create your first Qt GUI application using Qt3. You can use Qt designer (designerq-qt3 in a terminal command) and then how to compile it to produce or make an executable file program.

Open Qt3 Designer
Qt Designer is similar interface to Visual Basic IDE but it's absolutely different. Qt Designer which is its executable file name is designer-qt3 is for designing the form only. It couldn't be used for compiling program or debugging. Qt Designer will show the preview of form only, unlike a Visual Basic that you can try your program by pressing F5.

But, Qt Designer is a powerful tool to design a GUI in a minute only using drag and drop Widget from toolbox like a Visual Basic. To open Qt Designer use the following command.

open terminal and type :
