|
inlineoverrideprotectedvirtual |
Makes a copy of the widget if you don't know its exact type.
This function should only be used when you don't know the type of the widget. If you know what kind of widget you are copying, you should use the copy function.
Implements tgui::Widget.
|
static |
Makes a copy of another slider.
slider | The other slider |
|
static |
Creates a new slider widget.
minimum | The minimum value of the slider |
maximum | The maximum value of the slider |

The minimum is normally located on the left (for horizontal slider) or bottom (for vertical slider) side.
float tgui::Slider::getMaximum | ( | ) | const |
Returns the maximum value.
The default maximum value is 100.
float tgui::Slider::getMinimum | ( | ) | const |
Returns the minimum value.
The default minimum value is 0.

Sets a minimum value.
minimum | The new minimum value |
When the value is too small then it will be changed to this minimum. When the maximum value is lower than the new minimum then it will be changed to this new minimum value. The default minimum value is 0.
