MFC Example:
A Slider Control, CSliderCtrl

Pedro Pombeiro
What does it do?
This derivation of CSliderCtrl
allows the user to use the mouse or the keyboard to select
a range in the slider control. The program can then use CSliderCtrl::GetSelection()
to retrieve the range selected by the user. This is the
way I thought that CSliderCtrl
worked in the first place, only to discover that the
selection was just a static representation of the values
set by CSliderCtrl::SetSelection().
This class corrects this shortcoming of the
slider control.
How to use it?
This code was originally
compiled and tested with Visual
C++ 4.2 and WinNT 4.0 SP4. It should not
present any problem when using a more recent version of
the compiler.
Be aware that you need to
turn on the TBS_ENABLESELRANGE
style for the control.
The usage is very simple
you just have to include the files in your project,
replace the ocurrences of CSliderCtrl
in your code for CSelectionSliderCtrl and include
SelectionSliderCtrl.h. For example
#include "SelectionSliderCtrl.h"
class CMyDialog public CDialog
{
...
enum { IDD = IDD_MY_DIALOG };
CSelectionSliderCtrl m_sliderTest;
...
};
