Member Function Documentation

qreal DateTimeGrid::dayWidth ( ) const

Returns: The width in pixels for each day in the grid.

The default is 100 pixels.

Definition at line 319 of file kdganttdatetimegrid.cpp.

QSet< Qt::DayOfWeek > DateTimeGrid::freeDays ( ) const

Returns: The days marked as free in the grid.

Definition at line 443 of file kdganttdatetimegrid.cpp.

bool DateTimeGrid::mapFromChart	(	const Span &	span,
		const QModelIndex &	idx,
		const QList< Constraint > &	constraints = `QList<Constraint>()`
	)		const

virtual

Maps the supplied Span to QDateTimes, and puts them as start time and end time for the supplied index.

Parameters

span	The span used to map from.
idx	The index used for setting the start time and end time in the model.
constraints	A list of hard constraints to match against the start time and end time mapped from the span.

Returns: true if the start time and time was successfully added to the model, or false if unsucessful. Also returns false if any of the constraints isn't satisfied. That is, if the start time of the constrained index is before the end time of the dependency index, or the end time of the constrained index is before the start time of the dependency index.

Implements KDGantt::AbstractGrid.

Definition at line 538 of file kdganttdatetimegrid.cpp.

Definition at line 890 of file kdganttdatetimegrid.cpp.

void DateTimeGrid::paintGrid	(	QPainter *	painter,
		const QRectF &	sceneRect,
		const QRectF &	exposedRect,
		AbstractRowController *	rowController = `0`,
		QWidget *	widget = `0`
	)

virtual

Implement this to paint the background of the view – typically with some grid lines.

Parameters

painter	– the QPainter to paint with.
sceneRect	– the total bounding rectangle of the scene.
exposedRect	– the rectangle that needs to be painted.
rowController	– the row controller used by the view – may be 0.
widget	– the widget used by the view – may be 0.

Implements KDGantt::AbstractGrid.

Definition at line 641 of file kdganttdatetimegrid.cpp.

void DateTimeGrid::paintHeader	(	QPainter *	painter,
		const QRectF &	headerRect,
		const QRectF &	exposedRect,
		qreal	offset,
		QWidget *	widget = `0`
	)

virtual

Implement this to paint the header part of the view.

Parameters

painter	– the QPainter to paint with.
headerRect	– the total rectangle occupied by the header.
exposedRect	– the rectangle that needs to be painted.
offset	– the horizontal scroll offset of the view.
widget	– the widget used by the view – may be 0.

Implements KDGantt::AbstractGrid.

Definition at line 747 of file kdganttdatetimegrid.cpp.

void DateTimeGrid::paintHourScaleHeader	(	QPainter *	painter,
		const QRectF &	headerRect,
		const QRectF &	exposedRect,
		qreal	offset,
		QWidget *	widget = `0`
	)

protectedvirtual

Paints the hour scale header.

Definition at line 854 of file kdganttdatetimegrid.cpp.

void DateTimeGrid::paintUserDefinedHeader	(	QPainter *	painter,
		const QRectF &	headerRect,
		const QRectF &	exposedRect,
		qreal	offset,
		const DateTimeScaleFormatter *	formatter,
		QWidget *	widget = `0`
	)

Definition at line 824 of file kdganttdatetimegrid.cpp.

bool DateTimeGrid::rowSeparators ( ) const

Returns: true if row separators are used.

Definition at line 449 of file kdganttdatetimegrid.cpp.

DateTimeGrid::Scale DateTimeGrid::scale ( ) const

Returns: The scale used to paint the grid.

The default is ScaleAuto, which means the day scale will be used as long as the day width is less or equal to 500.

See also: Scale

Definition at line 366 of file kdganttdatetimegrid.cpp.

void DateTimeGrid::setDayWidth ( qreal w )

Parameters

w	The width in pixels for each day in the grid.

The signal gridChanged() is emitted after the day width is changed.

Definition at line 342 of file kdganttdatetimegrid.cpp.

void DateTimeGrid::setFreeDays ( const QSet< Qt::DayOfWeek > & fd )

Parameters

fd	A set of days to mark as free in the grid.

Free days are filled with the alternate base brush of the palette used by the view. The signal gridChanged() is emitted after the free days are changed.

Definition at line 436 of file kdganttdatetimegrid.cpp.

void DateTimeGrid::setNoInformationBrush ( const QBrush & brush )

Sets the brush used to display rows where no data is found. Default is a red pattern. If set to QBrush() rows with no information will not be marked.

Definition at line 463 of file kdganttdatetimegrid.cpp.

void DateTimeGrid::setRowSeparators ( bool enable )

Parameters

enable Whether to use row separators or not.

Definition at line 454 of file kdganttdatetimegrid.cpp.

void DateTimeGrid::setScale ( Scale s )

Parameters

s	The scale to be used to paint the grid.

The signal gridChanged() is emitted after the scale has changed.

See also: Scale

Definition at line 354 of file kdganttdatetimegrid.cpp.

void DateTimeGrid::setStartDateTime ( const QDateTime & dt )

Parameters

dt	The start date of the grid. It is used as the beginning of the horizontal scrollbar in the view.

Emits gridChanged() after the start date has changed.

Definition at line 309 of file kdganttdatetimegrid.cpp.

void DateTimeGrid::setUserDefinedLowerScale ( DateTimeScaleFormatter * lower )

Sets the scale formatter for the lower part of the header to the user defined formatter to lower. The DateTimeGrid object takes ownership of the formatter, which has to be allocated with new.

You have to set the scale to ScaleUserDefined for this setting to take effect.

See also: DateTimeScaleFormatter

Definition at line 378 of file kdganttdatetimegrid.cpp.

void DateTimeGrid::setUserDefinedUpperScale ( DateTimeScaleFormatter * upper )

Sets the scale formatter for the upper part of the header to the user defined formatter to upper. The DateTimeGrid object takes ownership of the formatter, which has to be allocated with new.

You have to set the scale to ScaleUserDefined for this setting to take effect.

See also: DateTimeScaleFormatter

Definition at line 392 of file kdganttdatetimegrid.cpp.

void DateTimeGrid::setWeekStart ( Qt::DayOfWeek ws )

Parameters

ws	The start day of the week.

A solid line is drawn on the grid to mark the beginning of a new week. Emits gridChanged() after the start day has changed.

Definition at line 418 of file kdganttdatetimegrid.cpp.

QDateTime DateTimeGrid::startDateTime ( ) const

Returns: The QDateTime used as start date for the grid.

The default is three days before the current date.

Definition at line 299 of file kdganttdatetimegrid.cpp.

DateTimeScaleFormatter * DateTimeGrid::userDefinedLowerScale ( ) const

Returns: The DateTimeScaleFormatter being used to render the lower scale.

Definition at line 401 of file kdganttdatetimegrid.cpp.

DateTimeScaleFormatter * DateTimeGrid::userDefinedUpperScale ( ) const

Returns: The DateTimeScaleFormatter being used to render the upper scale.

Definition at line 408 of file kdganttdatetimegrid.cpp.

Qt::DayOfWeek DateTimeGrid::weekStart ( ) const

Returns: The start day of the week
