Depending on the control, the knob can be a window style bit or a flag in some structure (e.g. The technique is useful only for changing how the particular control (or its item) is painted, and it can only be used for controls which implement a support for it.Ĭontrols which provide such support, always have some knob, which can be used by the application to specify that it shall paint the control (or its item) on its own.

For our purposes, we will use the term "control customization" for augmenting the control's look or behavior, which involves a (non-trivial) code on the application side. instructing the control to paint differently) can be understood as a simple example of control customization. Actually, even setting of a control style (e.g. The two cases overlap and different people may have different opinion where one ends and the other one begins.

In addition, the topic is also interesting when you are implementing new control from scratch: Good controls allow the applicatoion some level of customization, and some customization techniques do require some support from the control itself. In today's article we will take a look on several techniques how to customize existing controls. However, implementing new control from scratch is often a lot of work, and in many cases the desired effect can also be achieved by augmenting behavior, look or both of an existing control, often with much less effort.
