DrawRect() [1/2]

void daisy::ColorGraphicsDisplay::DrawRect ( const Rectangle & rect, bool on, bool fill = false )

inline

Draws a rectangle.

Parameters

x2	x Coordinate of the second point
y2	y Coordinate of the second point
on	on or off
fill	fill the rectangle or draw only the outline

Implemented in daisy::ColorGraphicsDisplayImpl< ChildType >, and daisy::ColorGraphicsDisplayImpl< OledColorDisplay< DisplayDriver > >.

Fill()

virtual void daisy::ColorGraphicsDisplay::Fill ( bool on )

pure virtual

Fills the entire display with either on/off.

Parameters

on	Sets on or off.

Implemented in daisy::OledColorDisplay< DisplayDriver >.

GetBounds()

Rectangle daisy::ColorGraphicsDisplay::GetBounds ( ) const

inline

Height()

virtual uint16_t daisy::ColorGraphicsDisplay::Height ( ) const

pure virtual

Implemented in daisy::OledColorDisplay< DisplayDriver >.

SetColorBG()

virtual void daisy::ColorGraphicsDisplay::SetColorBG ( uint8_t red, uint8_t green, uint8_t blue )

pure virtual

Set background color

Parameters

red	Red color
green	Green color
blue	Blue color

Implemented in daisy::OledColorDisplay< DisplayDriver >.

SetColorFG()

virtual void daisy::ColorGraphicsDisplay::SetColorFG ( uint8_t red, uint8_t green, uint8_t blue )

pure virtual

Set foreground color

Parameters

red	Red color
green	Green color
blue	Blue color

Implemented in daisy::OledColorDisplay< DisplayDriver >.

SetCursor()

void daisy::ColorGraphicsDisplay::SetCursor ( uint16_t x, uint16_t y )

inline

Moves the 'Cursor' position used for WriteChar, and WriteStr to the specified coordinate.

Parameters

x	x pos
y	y pos

Update()

virtual void daisy::ColorGraphicsDisplay::Update ( )

pure virtual

Writes the current display buffer to the OLED device using SPI or I2C depending on how the object was initialized.

Implemented in daisy::OledColorDisplay< DisplayDriver >.

Width()

virtual uint16_t daisy::ColorGraphicsDisplay::Width ( ) const

pure virtual

Implemented in daisy::OledColorDisplay< DisplayDriver >.

WriteChar()

virtual char daisy::ColorGraphicsDisplay::WriteChar ( char ch, FontDef font, bool on )

pure virtual

Writes the character with the specific FontDef to the display buffer at the current Cursor position.

Parameters

ch	character to be written
font	font to be written in
on	on or off

Returns

&

Implemented in daisy::ColorGraphicsDisplayImpl< ChildType >, and daisy::ColorGraphicsDisplayImpl< OledColorDisplay< DisplayDriver > >.

WriteString()

virtual char daisy::ColorGraphicsDisplay::WriteString ( const char * str, FontDef font, bool on )

pure virtual

Similar to WriteChar, except it will handle an entire String. Wrapping does not happen automatically, so the width of the string must be kept within the dimensions of the screen.

Parameters

str	string to be written
font	font to use
on	on or off

Returns

&

Implemented in daisy::ColorGraphicsDisplayImpl< ChildType >, and daisy::ColorGraphicsDisplayImpl< OledColorDisplay< DisplayDriver > >.

WriteStringAligned()

virtual Rectangle daisy::ColorGraphicsDisplay::WriteStringAligned ( const char * str, const FontDef & font, Rectangle boundingBox, Alignment alignment, bool on )

pure virtual

Similar to WriteString but justified within a bounding box.

Parameters

str	string to be written
font	font to use
boundingBox	the bounding box to draw the text in
alignment	the alignment to use
on	on or off

Returns

The rectangle that was drawn to

Implemented in daisy::ColorGraphicsDisplayImpl< ChildType >, and daisy::ColorGraphicsDisplayImpl< OledColorDisplay< DisplayDriver > >.
