| The slider component being used in this component. | |
A PropertyComponent that shows its value as a slider.
| SliderPropertyComponent::SliderPropertyComponent | ( | const String & | propertyName, |
| double | rangeMin, | ||
| double | rangeMax, | ||
| double | interval, | ||
| double | skewFactor = 1.0 |
||
| ) | [protected] |
Creates the property component.
The ranges, interval and skew factor are passed to the Slider component.
If you need to customise the slider in other ways, your constructor can access the slider member variable and change it directly.
| SliderPropertyComponent::SliderPropertyComponent | ( | const Value & | valueToControl, |
| const String & | propertyName, | ||
| double | rangeMin, | ||
| double | rangeMax, | ||
| double | interval, | ||
| double | skewFactor = 1.0 |
||
| ) |
Creates the property component.
The ranges, interval and skew factor are passed to the Slider component.
If you need to customise the slider in other ways, your constructor can access the slider member variable and change it directly.
| SliderPropertyComponent::~SliderPropertyComponent | ( | ) |
Destructor.
| virtual void SliderPropertyComponent::setValue | ( | double | newValue ) | [virtual] |
Called when the user moves the slider to change its value.
Your subclass must use this method to update whatever item this property represents.
| virtual double SliderPropertyComponent::getValue | ( | ) | const [virtual] |
Returns the value that the slider should show.
| void SliderPropertyComponent::refresh | ( | ) | [virtual] |
Updates the property component if the item it refers to has changed.
A subclass must implement this method, and other objects may call it to force it to refresh itself.
The subclass should be economical in the amount of work is done, so for example it should check whether it really needs to do a repaint rather than just doing one every time this method is called, as it may be called when the value being displayed hasn't actually changed.
Implements PropertyComponent.
| void SliderPropertyComponent::sliderValueChanged | ( | Slider * | slider ) | [virtual] |
Called when the slider's value is changed.
This may be caused by dragging it, or by typing in its text entry box, or by a call to Slider::setValue().
You can find out the new value using Slider::getValue().
Implements Slider::Listener.
Slider SliderPropertyComponent::slider [protected] |
The slider component being used in this component.
Your subclass has access to this in case it needs to customise it in some way.
