Public Member Functions | |
virtual | ~Font () |
Destructor. | |
virtual int | getWidth (const std::string &text) const =0 |
Gets the width of a string. | |
virtual int | getHeight () const =0 |
Gets the height of the glyphs in the font. | |
virtual int | getStringIndexAt (const std::string &text, int x) |
Gets a string index in a string providing an x coordinate. | |
virtual void | drawString (Graphics *graphics, const std::string &text, int x, int y)=0 |
Draws a string. |
virtual void gcn::Font::drawString | ( | Graphics * | graphics, | |
const std::string & | text, | |||
int | x, | |||
int | y | |||
) | [pure virtual] |
Draws a string.
NOTE: You normally won't use this function to draw text since Graphics contains better functions for drawing text.
graphics | a Graphics object to use for drawing. | |
text | the string to draw. | |
x | the x coordinate where to draw the string. | |
y | the y coordinate where to draw the string. |
Implemented in gcn::DefaultFont, and gcn::ImageFont.
Referenced by gcn::Graphics::drawText().
virtual int gcn::Font::getHeight | ( | ) | const [pure virtual] |
Gets the height of the glyphs in the font.
Implemented in gcn::DefaultFont, and gcn::ImageFont.
Referenced by gcn::DropDown::adjustHeight(), gcn::RadioButton::adjustSize(), gcn::CheckBox::adjustSize(), gcn::Window::draw(), gcn::ListBox::draw(), gcn::Label::draw(), gcn::Button::draw(), gcn::TextBox::keyPress(), gcn::TextBox::mousePress(), gcn::TextBox::scrollToCaret(), and gcn::ListBox::setSelected().
int gcn::Font::getStringIndexAt | ( | const std::string & | text, | |
int | x | |||
) | [virtual] |
Gets a string index in a string providing an x coordinate.
Used to retrive a string index (for a character in a string) at a certain x position. It is especially useful when a mouse clicks in a TextField and you want to know which character was clicked.
Reimplemented in gcn::DefaultFont, and gcn::ImageFont.

virtual int gcn::Font::getWidth | ( | const std::string & | text | ) | const [pure virtual] |
Gets the width of a string.
The width of a string is not necesserily the sum of all the widths of it's glyphs.
text | the string to return the width of. |
