		int16_t	y
	)		const

	)

inlineoverridevirtual

Measure text using the current font/size without drawing it.

Parameters

text	Null-terminated string to measure.
x	Baseline origin x coordinate.
y	Baseline origin y coordinate.
x1	Receives the left edge relative to the supplied origin.
y1	Receives the top edge relative to the supplied baseline.
w	Receives measured width in pixels.

inlineoverridevirtual

Return vertical logical resolution used by app coordinates.

Implements ersa::hal::IDisplay.

◆ init()

Result< void > ersa::test::MockDisplay::init ( )

inlineoverridevirtual

Implements ersa::hal::IDisplay.

◆ powerOff()

void ersa::test::MockDisplay::powerOff ( )

inlineoverridevirtual

Restore a state usable for drawing or refresh; implementations may reinitialize hardware.

Implements ersa::hal::IDisplay.

◆ print() [1/4]

size_t ersa::test::MockDisplay::print ( const char * text )

inlineoverridevirtual

Draw a null-terminated string at the current cursor and return its consumed character count. The pointer is borrowed for this call only.

Implements ersa::hal::IDisplay.

◆ print() [2/4]

size_t ersa::test::MockDisplay::print ( int32_t value )

Implements ersa::hal::IDisplay.

◆ refresh()

void ersa::test::MockDisplay::refresh ( bool full = false )

inlineoverridevirtual

Transmit the framebuffer to the panel.

Parameters

full	Request a full waveform when true; partial waveform otherwise.

Implements ersa::hal::IDisplay.

◆ refreshRect()

void ersa::test::MockDisplay::refreshRect ( const Rect & rect )

inlineoverridevirtual

Update only the specified region when the panel supports partial refresh. Drivers without region updates may safely promote this to a full refresh.

Implements ersa::hal::IDisplay.

◆ setBusyCallback()

void ersa::test::MockDisplay::setBusyCallback	(	hal::DisplayBusyCallback	cb,
		void *	userData = `nullptr`
	)

inlineoverridevirtual

Register a completion/wait callback for panel busy handling.

Parameters

cb	Callback invoked by the driver, or null to clear it.
userData	Opaque context passed back unchanged to `cb`.

Implements ersa::hal::IDisplay.

◆ setCursor()

void ersa::test::MockDisplay::setCursor	(	int16_t	x,
		int16_t	y
	)

inlineoverridevirtual

Set the text baseline origin used by subsequent print() calls.

Implements ersa::hal::IDisplay.

◆ setFont()

void ersa::test::MockDisplay::setFont ( hal::FontFace face )

◆ setTextColor()

void ersa::test::MockDisplay::setTextColor ( hal::Color color )

inlineoverridevirtual

Set the color used by subsequent print() calls.

Implements ersa::hal::IDisplay.

◆ setTextSize()

void ersa::test::MockDisplay::setTextSize ( uint8_t size )

inlineoverridevirtual

Set text scaling; size 1 is the backend's normal scale.

Implements ersa::hal::IDisplay.

◆ setTextWrap()

void ersa::test::MockDisplay::setTextWrap ( bool wrap )

inlineoverridevirtual

Control whether subsequent text wraps when it reaches the canvas edge.

Implements ersa::hal::IDisplay.

◆ width()

int16_t ersa::test::MockDisplay::width ( ) const

inlineoverridevirtual

Return horizontal logical resolution used by app coordinates.

Implements ersa::hal::IDisplay.
