Member Function Documentation

clampSelection()

void undoApp::Terminal::TerminalView::clampSelection ( )

private

colAt()

int undoApp::Terminal::TerminalView::colAt ( float  x ) const

private

copySelection()

void undoApp::Terminal::TerminalView::copySelection

(

TerminalSession &

session

)

Copy the selection to the clipboard.

Parameters

session

Session to copy from

draw()

void undoApp::Terminal::TerminalView::draw	(	TerminalSession &	session,
		ImFont *	font,
		float &	fontSize,
		bool	focused
	)

Draw the session inside the current ImGui window.

Parameters

session	Session to draw
font	Monospace font to draw with
fontSize	Size to draw it at, adjusted by Ctrl and the wheel
focused	Whether this pane holds the keyboard

The pane sizes the session to the space it was given, so a resize here is a real terminal resize as far as the shell is concerned. A larger font makes the cells larger and the session smaller: the grid cannot overlap, because every glyph is drawn inside a cell measured from that same font and size.

handleInput()

void undoApp::Terminal::TerminalView::handleInput	(	TerminalSession &	session,
		bool	focused,
		float &	fontSize,
		float	defaultSize
	)

Turn this frame's key presses into what the session should be sent.

Parameters

session	Session to send to
focused	Whether this pane holds the keyboard
fontSize	Size of the terminal, changed by the size keys
defaultSize	Size the reset key returns to

The size keys are answered here rather than in the panel, because the ones that matter arrive as characters and not as keys: on a layout where '+' is its own key, or typed as Shift and '=', the only thing ImGui reports is the character, so a check against a key code never sees it.

hasSelection()

bool undoApp::Terminal::TerminalView::hasSelection ( ) const

inline

Whether there is a selection to copy.

paste()

void undoApp::Terminal::TerminalView::paste

(

TerminalSession &

session

)

Paste the clipboard into the session.

Parameters

session

Session to paste into

rowAt()

int undoApp::Terminal::TerminalView::rowAt ( float  y ) const

private

zoom()

void undoApp::Terminal::TerminalView::zoom ( float &  fontSize, float  notches  ) const

private
