Detailed Description

Namespace which holds static GUI-related helper functions.

Function Documentation

convert() [1/2]

StringList OpenMS::GUIHelpers::convert

(

const QStringList &

in

)

convert() [2/2]

QStringList OpenMS::GUIHelpers::convert

(

const StringList &

in

)

drawText()

void OpenMS::GUIHelpers::drawText	(	QPainter &	painter,
		const QStringList &	text,
		const QPoint &	where,
		const QColor	col_fg = QColor("invalid"),
		const QColor	col_bg = QColor("invalid"),
		const QFont &	font = QFont("Courier")
	)

draw a multi-line text at coordinates XY using a specific font and color

Internally used getTextDimension() to figure out the size of the text-block/background which needs to be painted.

Parameters

painter	Where to draw
text	Each item is a new line
where	Coordinates where to start drawing (upper left corner of text)
col_fg	Optional text color; if invalid (=default) will use the current painter's color
col_bg	Optional background color of bounding rectangle; if invalid (=default) no background will be painted
font	Font to use; will use Courier by default

getTextDimension()

QRectF OpenMS::GUIHelpers::getTextDimension	(	const QStringList &	text,
		const QFont &	font,
		int &	line_spacing
	)

Obtains the bounding rectangle of a text (useful to determine overlaps etc)

openFolder()

void OpenMS::GUIHelpers::openFolder

(

const QString &

folder

)

Open a folder in file explorer Will show a message box on failure

openURL()

void OpenMS::GUIHelpers::openURL

(

const QString &

target

)

Open a certain URL (in a browser) Will show a message box on failure

startTOPPView()

void OpenMS::GUIHelpers::startTOPPView

(

const QStringList &

args

)
