bar, and toolbar. the customer area coordinate system is the origin point in the upper left corner of the window client area, which is mainly used for drawing output and window message processing of the client area. The coordinate parameter of the mouse message uses the client area coordinates, and the CDC class drawing member function uses the logical coordinates that correspond to the client area coordinates.(2) mutual conversion between coordinate

EnvironmentThe device environment itself is a GDI (Graphics device Interface) object. Each C + + device object has a related device environment, which is identified by a 32-bit HDC type handle. GDI is a set of interface functions in a Windows core DLL. These functions are on top of the hardware driver, and when the application calls these functions, they then invoke the interface functions provided by the driver.The MFC 6.0 release provides a large number of device environment types. The base c

MFC has a powerful function and has a complete drawing function. On the Windows platform, the application's Graphics Device interface (INTERFACE,GDI) is abstracted into device CONTEXT,DC. In Microsoft's base Class library MFC, the CDC class is the base class that defines the device context object, and all the drawing functions are defined in the CDC base class. When you need to output text or graphics, you

Generally, programmers want their programs to be beautiful and generous. To meet this requirement, they want to do their best to beautify their programs. On the other hand, text is an indispensable way to transmit information on the program interface. It is a good choice to add and display texts with special effects in appropriate places on the interface, you can get twice the result with half the effort. This example describes how to achieve this goal by writing a simple small program to solve

by the drawing speed being too slow or the display graphics being too complex. In fact, this is not true. The influence of the display speed of the drawing on the flashing is not fundamental. For example, in ondraw (CDC * PDC), write as follows: PDC-> moveTo (0, 0 ); PDC-> lineto (100,100 ); This drawing process should be very simple and fast, but it will still flash when pulling the window changes. In fact, in principle, the more complex the proc

)); ... } When you need to re-draw a dialog (or a sub-control of the dialog), Windows sends the message wm_ctlcolor to the dialog. Generally, you can ask windows to select a paint brush for the background or reset the specified brush for the message. The following example describes how to create a red background dialog. First, add the one-person member variable cbursh to the dialog base class: Class cmyformview: Public cformview { ... PRIVATE: Cbrush M _ brush; // background brush ... }; Second

But these functions are added as member functions, not overloads. The print and OnPrint functions are mainly introduced here.
