Trackbar Styles

Trackbars can have either a vertical or horizontal orientation. They can have tick marks on either side, both sides, or neither. They can also be used to specify a range of consecutive values. These properties are controlled by using trackbar styles, which you specify when you create the trackbar.

The TBS_HORZ and TBS_VERT styles determine the orientation of the trackbar. If you do not specify an orientation, the trackbar is oriented horizontally.

The TBS_AUTOTICKS style creates a trackbar that has a tick mark for each increment in its range of values. These tick marks are added automatically when an application sends the TBM_SETRANGE message. If you do not specify TBS_AUTOTICKS, you can use messages, such as TBM_SETTIC and TBM_SETTICFREQ, to specify the positions of the tick marks. To create a trackbar that does not display tick marks, you can use the TSM_NOTICKS style.

You can display tick marks on either or both sides of the trackbar. For horizontal trackbars, you can specify the TBS_BOTTOM or TBS_TOP style. For vertical trackbars, you can specify the TBS_RIGHT or TBS_LEFT style. (TBS_BOTTOM and TBS_RIGHT are the default settings.) For tick marks on both sides of the trackbar in any orientation, specify the TBS_BOTH style.

A trackbar can display a selection range only if you specify the TBS_ENABLESELRANGE style when you create it. When a trackbar has this style, the tick marks at the starting and ending positions of a selection range are displayed as triangles (instead of vertical dashes) and the selection range is highlighted. For example, selection ranges might be useful in a simple scheduling application. The user could select a range of tick marks corresponding to hours in a day to identify a scheduled meeting time.

By default, the length of a trackbar's slider varies as the selection range changes. If the trackbar has the TBS_FIXEDLENGTH style, the length of the slider remains the same even if the selection range changes. A trackbar that has the TBS_NOTHUMB style does not include a slider.

    Nostalgia .Net     .Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native.
