Detailed Description

Widget to display and change the current array slice.

Synopsis

A TBSlicer has two parts: the bottom part allows the user to chooser which dimension is viewed along the two axes, and the top part chooses which "slice" along those two axes to view. When the user changes the slice, a signal is emitted; the parent/caller is responsible for connecting and processing the signal.

Member Function Documentation

void casa::TBSlicer::colAxisChanged ( int  newCol )

privateslot

Slot for when the column axis dimension is changed.

Updates the slicer accordingly.

void casa::TBSlicer::emitSliceChanged ( )

private

Collects the slice and emits the sliceChanged() signal.

void casa::TBSlicer::rowAxisChanged ( int  newRow )

privateslot

Slot for when the row axis dimension is changed.

Updates the slicer accordingly.

void casa::TBSlicer::sliceChanged ( std::vector< int >  slice )

signal

This signal is emitted when the user changes the slice.

The slice parameter contains non-negative values along all dimensions EXCEPT for the two dimensions that are mapped to the X- and Y-axes. The dimension mapped to the X-axis has the value TBConstants::SLICER_ROW_AXIS in the vector while the dimension mapped to the Y-axis has the value TBConstants::SLICER_COL_AXIS in the vector. For example, if the array was 4x4x4, a slice of [SLICER_ROW_AXIS 1 SLICER_COL_AXIS] would mean to display the first dimension along the X-axis and the third dimension along the Y-axis and to use 1 as the index for the second dimension.

void casa::TBSlicer::valueChanged ( )

privateslot

Slot for when one of the spinners changes values.

Updates the current slice and calls emitSliceChanged() if the slice has changed.
