Member Function Documentation

void vtkQtChartAxisModel::addLabel

(

const QVariant &

label

)

Adds a label to the chart axis.

Parameters:

label

The label to add.

void vtkQtChartAxisModel::insertLabel	(	int	index,
		const QVariant &	label
	)

Adds a label to the chart axis.

Parameters:

index	Where to insert the label.
label	The label to add.

void vtkQtChartAxisModel::removeLabel

(

int

index

)

Removes a label from the chart axis.

Parameters:

index

The index of the label to remove.

void vtkQtChartAxisModel::removeAllLabels

(

)

Removes all the labels from the chart axis.

void vtkQtChartAxisModel::startModifyingData

(

)

Blocks the model modification signals.

This method should be called before making multiple changes to the model. It will prevent the view from updating before the changes are complete. Once all the changes are made, the finishModifyingData method should be called to notify the view of the changes.

See also:

vtkQtChartAxisModel::finishModifyingData()

void vtkQtChartAxisModel::finishModifyingData

(

)

Unblocks the model modification signals.

The labelsReset signal is emitted to synchronize the view.

See also:

vtkQtChartAxisModel::startModifyingData()

int vtkQtChartAxisModel::getNumberOfLabels

(

)

const

Gets the number of labels in the chart axis.

Returns:

The number of labels in the chart axis.

void vtkQtChartAxisModel::getLabel	(	int	index,
		QVariant &	label
	)		const

Gets a specified chart axis label.

Parameters:

index	Which chart axis to get.
label	Used to return the label.

int vtkQtChartAxisModel::getLabelIndex

(

const QVariant &

label

)

const

Gets the index of the given label.

Parameters:

label

The label value to find.

Returns:

The index of the label or -1 if not found.

void vtkQtChartAxisModel::labelInserted

(

int

index

)

[signal]

Emitted when a new label is added.

Parameters:

index

Where the label was added.

void vtkQtChartAxisModel::removingLabel

(

int

index

)

[signal]

Emitted before a label is removed.

Parameters:

index

The index being removed.

void vtkQtChartAxisModel::labelRemoved

(

int

index

)

[signal]

Emitted after a label is removed.

Parameters:

index

The index being removed.

void vtkQtChartAxisModel::labelsReset

(

)

[signal]
