Re: user icon on balloon tooltip Atony Chen Oct Could you give me more detail on this point? Life is hard. Hi, first of all nice work. How can i do that? Notification area icons should be high-DPI aware.

An application should provide both a 16x16 pixel icon and a 32x32 icon in its resource file, and then use LoadIconMetric to ensure that the correct icon is loaded and scaled appropriately.

The application responsible for the notification area icon should handle a mouse click for that icon. When a user right-clicks the icon, it should bring up a normal shortcut menu. However, the result of a single click with the left mouse button will vary with the function of the icon.

It should display what the user would expect to see in the form best suited to that content—a popup window, a dialog box or the program window itself. For instance, it could show status text for a status icon, or a slider for the volume control. The placement of a popup window or dialog box that results from the click should be placed near the coordinate of the click in the notification area. Use the CalculatePopupWindowPosition to determine its location. To do so, continue with the instructions in this topic.

This version provides the full available functionality, including the preferred ability to identify the notification area icon though a registered GUID, a superior callback mechanism, and better accessibility. A notification is a special type of balloon tooltip control. It contains a title, body text, and an icon.

Like a window, it has a Close button in its upper right corner. It also contains a Options button that opens the Notification Area Icons item in the Control Panel, which allows the user to show or hide the icon or show only notifications without an icon.

The system uses the SHQueryUserNotificationState function is used to check whether the user is in quiet time, away from the computer, or in an uninterruptable state such as Presentation mode. Whether the system displays your notification depends on this state. Notifications sent when the user is away are queued for display, but because you cannot know when the user will return or whether the notification will still be valid at that time, you might consider resending the notification later.

Notifications sent during quiet time are discarded unshown. Design guidelines ask that all notifications be ignorable. They should not require immediate user action. Therefore, no notification is so important that it should override quiet time. In this way, the system can notify an application when the user, for instance, clicks the icon or selects it by pressing a key. You define an icon's callback message when you add the icon to the taskbar.

When an event occurs, the system sends the callback message to the window procedure of the window specified by the hWnd member. The wParam parameter of the message contains the identifier of the taskbar icon in which the event occurred. The lParam parameter holds the mouse or keyboard message associated with the event. Typically, clicking the icon causes the application to display a window with additional information, right-clicking displays a shortcut menu, and double-clicking executes the default shortcut menu command.

For an example of how to change the tooltip text associated with a notification area icon, see Balloon Tooltips for Status Bar Icons. Versions 5. The differences are as follows:. With Microsoft Internet Explorer 4.

When the taskbar is created, it registers a message with the TaskbarCreated string and then broadcasts this message to all top-level windows. When your taskbar application receives this message, it should assume that any taskbar icons it added have been removed and add them again. This feature generally applies only to services that are already running when the Shell launches. The following example shows a very simplified method for handling this case.

On Windows 10, the taskbar also broadcasts this message when the DPI of the primary display changes. This section includes examples that demonstrate how to add icons to the taskbar notification area and how to process callback messages for taskbar icons.

The structure members must specify the handle to the window that is adding the icon, as well as the icon identifier and icon handle. You can also specify tooltip text for the icon. If you need to receive mouse messages for the icon, specify the identifier of the callback message that the system should use to send the message to the window procedure.

When deleting a taskbar icon, specify only the cbSize , hWnd , and uID members of the structure. For example:. If you specify a callback message for a taskbar icon, the system sends the message to your application whenever a mouse event occurs in the icon's bounding rectangle. The wParam parameter of the message specifies the identifier of the taskbar icon, and the lParam parameter of the message specifies the message that the system generated as a result of the mouse event.

The function in the following example is from an application that adds both battery and printer icons to the taskbar. The application calls the function when it receives a callback message. The function determines whether the user has clicked one of the icons and, if a click has occurred, calls an application-defined function to display status information. Skip to main content.
