An abstract base class for slider widgets.
39
<a class="el" href="class_qwt_abstract_slider.html">QwtAbstractSlider</a> is a base class for slider widgets. It handles mouse events and updates the slider's value accordingly. Derived classes only have to implement the <a class="el" href="class_qwt_abstract_slider.html#6e26a993536813c2d9846a28f3c27aa7">getValue()</a> and <a class="el" href="class_qwt_abstract_slider.html#dcb6819c88cfa27e9ea3d8828479ea0b">getScrollMode()</a> members, and should react to a <a class="el" href="class_qwt_abstract_slider.html#2f04dc51e4402b51fef3250bcc99dc7f">valueChange()</a>, which normally requires repainting.

This function can be reimplemented by derived classes in order to keep track of changes, i.e. repaint the widget. The default implementation emits a <a class="el" href="class_qwt_abstract_slider.html#6bc5c410cd56119c6ad50743c9a46af1">valueChanged()</a> signal if tracking is enabled.
