Detailed Description

This class defines a genric GUI component. A GuiComponent is a little more than a Orthographic camera. It defines serveral states, wich determine what is getting rendered and knows its bounding box.

Member Enumeration Documentation

enum GuiComponent::State

This enumeration holds the possible states of the self made GUI components (e.g. the Histogram, the Colorselector). The States can be set without restrictions. HIDDEN In this state, the comonent is not rendered and does not react to user interactions ENABLED In this state, the component gets rendered and respond to user interaction DISABLED In this state, the component gets rendered but does not respond to user interaction UPDATING In this state the component is updated. This state is needed to prevent refresh of the component as long as it is busy. Definition at line 32 of file GuiComponent.h.

Constructor & Destructor Documentation

GuiComponent::GuiComponent (  int  left, int  right, int  bottom, int  top, int  x, int  y, int  width, int  height )

Create an orthographic projection space and a viewport using the camera class. So each component exists into its own space. Definition at line 6 of file GuiComponent.cpp.

Member Function Documentation

void GuiComponent::disable (   )

Set the state to DISABLED Definition at line 22 of file GuiComponent.cpp. References state. Referenced by ColorCubePanel::onMouseDown().

void GuiComponent::enable (   )

Set the state to ENABLED Definition at line 17 of file GuiComponent.cpp. References state. Referenced by Histogram::update().

void GuiComponent::hide (   )

Set the state to HIDDEN Definition at line 26 of file GuiComponent.cpp. References state. Referenced by Histogram::update().

bool GuiComponent::hit (  int  x, int  y )

Find out if the component had been picked by the mouse. This will always return false, if the state is not equal to ENABLED Definition at line 55 of file GuiComponent.cpp. Referenced by Histogram::onLeftMouseClick(), ColorCubePanel::onMouseDown(), and Histogram::onMouseDrag().

bool GuiComponent::isDisabled (   )

Return if the current state is DISABLED Definition at line 45 of file GuiComponent.cpp.

bool GuiComponent::isEnabled (   )

Return if the current state is ENABLED Definition at line 35 of file GuiComponent.cpp.

bool GuiComponent::isHidden (   )

Return if the current state is HIDDEN Definition at line 40 of file GuiComponent.cpp.

bool GuiComponent::isUpdating (   )

Return if the current state is BUSY Definition at line 50 of file GuiComponent.cpp.

void GuiComponent::moveTo (  int  newX, int  newY )

Update the lower left position of the components viewport. Definition at line 12 of file GuiComponent.cpp.

void GuiComponent::updating (   )

Set the state to BUSY Definition at line 31 of file GuiComponent.cpp. References state.
