Introduction to Qt creatorThrough the previous "QT QuickStart (Vim Pure Code writing)" Learning that only set up the QT environment (QT Library and development tools ), you can use vim pure code to write QT program, and then use QT qmake tools to compile QT code, the specific process is as follows: 1) Write Qt code 2) generate project files via qmake-project 3" project file: QT + = widgets 5" to generate the required executable program by make compiled code

4. creator Mode 1. Motorcycle Assembly System These examples are suitable for beginners and easy to understand,After reading it, I got an impression on what it looks like. Motorcycle = frame + wheel + tire + engine. First, design motorcycles and various parts: Motorcycle: public interface motorcycle {void build ();} public class motorcycle1 implements motorcycle {void build () {sysout. out. println ("start assembling a motorcycle... ") ;}} motorcycle

not support PDF generation? I think that I can directly use the pdfcreator virtual printer every time I need to generate a PDF file. I checked it and found that the pdfcreator has a COM API. This problem is solved. In C #, how do I call the volume creator to generate a PDF file? Step 1: Install the volume creator (this seems nonsense) Step 2: Create a csung project and add creator.exe com to reference it S
