Encapsulated classes: Windows7Taskbar, ThumbButtonManager, ThumbButton, JumpListManager, RegistrationHelper, etc.
Windows7Taskbar is used for registration and initialization. ThumbButtonManager manages ThumbButton, including the create button, JumpListManager history, and RegistrationHelper associated file type.
Steps:
1. Reference
Using windows7.20.topintegration;
Using windows7.20.topintegration. WindowsForms;
2. Initialization (when loading the form)
Windows7Taskbar. AllowTaskbarWindowMessagesThroughUIPI ();
Windows7Taskbar. SetCurrentProcessAppId ("TaskbarManaged"); // you can customize the parameters.
3. Create button
ThumbButtonManager buttonManager = this. createThumbButtonManager (); ThumbButton taskbarBtnPause = buttonManager. createThumbButton (101, Properties. resources. playtask, "play"); taskbarBtnPause. clicked + = (sender, e) =>{ btnPlay_PictureClick (sender, e); if (IsPlay = true) // check whether the video is being played. Update the icon {taskbarBtnPause. icon = Properties. resources. playtask;} else {taskbarBtnPause. icon = Properties. resources. pausetask ;}
};
ButtonManager. AddThumbButtons (taskbarBtnPause );
4. capture information
protected override void WndProc(ref Message m)
{ if (buttonManager != null) buttonManager.DispatchMessage(ref m); base.WndProc(ref m);
}
:
Note that:
A maximum of seven buttons can be added or deleted. After initialization, you can only make them unavailable or hidden. You can call the ThumbBarAddButtons and ThumbBarUpdateButtons methods to control the toolbar.
Adding ThumbButton during the Load time of the form does not work, which is why I did not add ThumbButton when loading the form, and each ThumbButton has an ID, which is assigned by you, it cannot be repeated.
Problems:
I added a Processing Event to taskbarBtnPause. Clicked, that is, the change Icon. The result is that the ThumbButton attribute Icon is modified when the event is triggered, but the interface is not updated.
