Object PmgSlider (Slider)
Description:
Entering numeric value in the form of slider.
On running the application it is possible to change the slider value either by dragging the slider or by clicking the mouse on one of the arrows or by clicking the mouse on the slider background. The value is then fluently changed in the ValueMin, ValueMax range.

Note:
The slider value is accessible by means of the Value property. Its data binding specifies the variable into which the value corresponding to the slider button position is transferred in runtime. The data binding is here "for read and write", it means that if the value of the data binding is changed by other methods (e.g. in the script), then the change of this value is reflected into the slider button position.
The slider doesn't contain a visible scale, entering the value is only for the orientation. If it is necessary to show the scale or the entered value, then it can be used the more complex PmgSliderBox object.
For numeric entering the value the PmgNumber object (entering the value on the place in the object) can be used.
