Article 3 Use of menus, icons, and cursors

This blog will briefly introduce how to use menus, icons, and cursors in windows.

 

1. menus, icons, and cursors are defined as resources in the resource file.

1. Menu definition method:

Menu ID menu [discardable]

Begin

Menu item Definition

End

 

Menu item definition:

Define common menu items:

Menuitem menu text, command ID [, Option List]

Define the split line:

Menuitem Separator

Define the pop-up menu:

Popup menu text [, Option List]

Begin

Menu item Definition

End

 

2. Definition of icons and cursors

Icon ID icon [discardable] icon file name

Cursor ID cursor [discardable] Name of the cursor file

 

3. Note

The so-called xxid values are user-defined values in the range of 0 ~ 0 ffffh

Discardable is the memory option, indicating that the memory can be automatically released when not in use

2. Use menus, icons, and cursor Resources in the main window Program

1. How to Create a window: the first window Program

 

2. Usage

① Use menu

First, load the menu (specified by the menu ID-IDM_MAIN) into the application after obtaining the module handle

invokeGetModuleHandle,NULLmovhInstance,eaxinvokeLoadMenu,hInstance,IDM_MAINmovhMenu,eax

Secondly, when a window is created, the menu handle hmenu is passed as a parameter.

invokeCreateWindowEx,WS_EX_CLIENTEDGE,\offset szClassName,offset szClassName,\WS_OVERLAPPEDWINDOW,\200,200,300,200,\NULL,hMenu,hInstance,NULL

② How to use the cursor and icon

When createdomainwex is called to create a window, the system sends a wm_create message to the window program before the function returns. We can

Load the cursor and Icon resource. Then call the sendmessage function to send the default icon and cursor type to the window program.

Sequential processing.
