Member Function Documentation

§ getActiveFont()

virtual IGUIFont* irr::gui::IGUIButton::getActiveFont ( ) const
pure virtual

Get the font which is used right now for drawing.

Currently this is the override font when one is set and the font of the active skin otherwise

§ getOverrideFont()

virtual IGUIFont* irr::gui::IGUIButton::getOverrideFont ( void  ) const
pure virtual

Gets the override font (if any)

Returns
The override font (may be 0)

§ isAlphaChannelUsed()

virtual bool irr::gui::IGUIButton::isAlphaChannelUsed ( ) const
pure virtual

Returns if the alpha channel should be used for drawing background images on the button.

§ isDrawingBorder()

virtual bool irr::gui::IGUIButton::isDrawingBorder ( ) const
pure virtual

Returns if the border and button face are being drawn using the skin.

§ isPressed()

virtual bool irr::gui::IGUIButton::isPressed ( ) const
pure virtual

Returns if the button is currently pressed.

§ isPushButton()

virtual bool irr::gui::IGUIButton::isPushButton ( ) const
pure virtual

Returns whether the button is a push button.

§ isScalingImage()

virtual bool irr::gui::IGUIButton::isScalingImage ( ) const
pure virtual

Checks whether the button scales the used images.

§ setDrawBorder()

virtual void irr::gui::IGUIButton::setDrawBorder ( bool  border = true)
pure virtual

Sets if the button should use the skin to draw its border and button face (default is true)

§ setImage() [1/2]

virtual void irr::gui::IGUIButton::setImage ( video::ITexture image = 0)
pure virtual

Sets an image which should be displayed on the button when it is in normal state.

Parameters
imageImage to be displayed

§ setImage() [2/2]

virtual void irr::gui::IGUIButton::setImage ( video::ITexture image,
const core::rect< s32 > &  pos 
)
pure virtual

Sets a background image for the button when it is in normal state.

Parameters
imageTexture containing the image to be displayed
posPosition in the texture, where the image is located

§ setIsPushButton()

virtual void irr::gui::IGUIButton::setIsPushButton ( bool  isPushButton = true)
pure virtual

Sets if the button should behave like a push button.

Which means it can be in two states: Normal or Pressed. With a click on the button, the user can change the state of the button.

§ setOverrideFont()

virtual void irr::gui::IGUIButton::setOverrideFont ( IGUIFont font = 0)
pure virtual

Sets another skin independent font.

If this is set to zero, the button uses the font of the skin.

Parameters
fontNew font to set.

§ setPressed()

virtual void irr::gui::IGUIButton::setPressed ( bool  pressed = true)
pure virtual

Sets the pressed state of the button if this is a pushbutton.

§ setPressedImage() [1/2]

virtual void irr::gui::IGUIButton::setPressedImage ( video::ITexture image = 0)
pure virtual

Sets a background image for the button when it is in pressed state.

If no images is specified for the pressed state via setPressedImage(), this image is also drawn in pressed state.

Parameters
imageImage to be displayed

§ setPressedImage() [2/2]

virtual void irr::gui::IGUIButton::setPressedImage ( video::ITexture image,
const core::rect< s32 > &  pos 
)
pure virtual

Sets an image which should be displayed on the button when it is in pressed state.

Parameters
imageTexture containing the image to be displayed
posPosition in the texture, where the image is located

§ setScaleImage()

virtual void irr::gui::IGUIButton::setScaleImage ( bool  scaleImage = true)
pure virtual

Sets if the button should scale the button images to fit.

§ setSprite()

virtual void irr::gui::IGUIButton::setSprite ( EGUI_BUTTON_STATE  state,
s32  index,
video::SColor  color = video::SColor(255, 255, 255, 255),
bool  loop = false 
)
pure virtual

Sets the animated sprite for a specific button state.

Parameters
indexNumber of the sprite within the sprite bank, use -1 for no sprite
stateState of the button to set the sprite for
indexThe sprite number from the current sprite bank
colorThe color of the sprite
loopTrue if the animation should loop, false if not

§ setSpriteBank()

virtual void irr::gui::IGUIButton::setSpriteBank ( IGUISpriteBank bank = 0)
pure virtual

Sets the sprite bank used by the button.

§ setUseAlphaChannel()

virtual void irr::gui::IGUIButton::setUseAlphaChannel ( bool  useAlphaChannel = true)
pure virtual

Sets if the alpha channel should be used for drawing background images on the button (default is false)
