TGTripleHSlider Class Reference

TripleSlider inherit from DoubleSlider widgets and allow easy selection of a min, max and pointer value out of a range.

The pointer position can be constrained to edges of slider and / or can be relative to the slider position.

To change the min value press the mouse near to the left / bottom edge of the slider. To change the max value press the mouse near to the right / top edge of the slider. To change both values simultaneously press the mouse near to the center of the slider. To change pointer value press the mouse on the pointer and drag it to the desired position

Dragging the slider will generate the event:

• kC_HSLIDER, kSL_POS, slider id, 0

Pressing the mouse will generate the event:

• kC_HSLIDER, kSL_PRESS, slider id, 0

Releasing the mouse will generate the event:

• kC_HSLIDER, kSL_RELEASE, slider id, 0

Moving the pointer will generate the event:

• kC_HSLIDER, kSL_POINTER, slider id, 0

Use the functions GetMinPosition(), GetMaxPosition() and GetPosition() to retrieve the position of the slider. Use the function GetPointerPosition() to retrieve the position of the pointer
