[Windows programming] Series 6: Creating Toolbar, Statusbar, and toolbarstatusbar

HIMAGELIST ImageList_Create (int cx, int cy, UINT flags, int cInitial, int cGrow );

 

The function usage is clear on MSDN. After the list is created, there is no image. It is just a list-managed container and you need to load the image set. The APIS required for adding images are as follows:

int ImageList_AddMasked(HIMAGELIST himl, HBITMAP hbmImage, COLORREF crMask);

 

After an image is loaded, you can set the display attributes of the image, including the image display, text, and information prompting functions. The response of the tool button is implemented by sending the WM_COMMAND message to the window handler, and the user can process the button event. The prompt message in the toolbar is sent through WM_NOTIFY, which is set by the user. For details about how to create an instance in the toolbar, refer to the application instance.

• Create Status Bar

The installation status bar is much simpler than the toolbar. After creating the status bar using createjavaswex, the status bar has only one display panel by default. You need to create multiple panels, send the SB_SETPARTS message to the status bar. The message parameters are the number of panels and the destination array of the Panel. For example:

int array[3]={120,120*2,-1};SendMessage(hWndStatus,SB_SETPARTS,(WPARAM)3,(LPARAM)array);

 

The status bar panel is divided into three parts, the first part is divided into 120 pixels, the second part is divided into 240 pixels, and the remaining (-1) is all divided into the third part.

Set panel text content. You can send SB_SETTEXT messages to the status bar. To add a small icon to the status bar, you can send SB_SETICON messages to the status bar.

The toolbar and status bar above only show the basic information. For more settings and message processing, refer to MSDN. This series focuses on basic programming and usage, but only introduces common usage. However, these usage can be used by beginners.

• Use instance

The following describes how to create and use the toolbar and status bar using pure Windows APIs through a basic instance program. The Toolbar created in the program has three icons. When the program is displayed normally, move the mouse over a Toolbar button or is in Disable state, different images are displayed, you can change the icons you like.

After the instance program, the result is displayed as follows:

After you press the "open" button on the toolbar of the program, it becomes Disable. After you click "save", the "open" button is activated again. As you can see, when you move the mouse over the "save" button, a text prompt indicating "Save As file" appears.

The status bar has three panels, and the last two are statically assigned strings at creation. The first is to capture and display the coordinates of the mouse in the customer zone in real time.

In general, the basic usage of the toolbar and status bar is relatively simple, but because these two controls are common controls of Microsoft, you need to call InitCommonControlsEx to initialize the universal control library and set the controls to be used before creation.
