Inheritance diagram for VectorEditor:

[legend]

List of all members.

Detailed Description

Allows editing of vector data of types point and line.

This captures viewer events produced by users such as mouse click and maps them to actions on the vectors themselves.

Author:: Dan Mingus

History:: 2004-12-04 Deborah Lee Soltesz - Improved the highlighting and selection to allow the GlacierIDDlg to highlight glacier ID selected by the VectorEditor, and to display vector objects in the View as selected when selected in the GlacierIDDlg.

History:: 2005-07-14 Deborah Lee Soltesz - Modified to use modifications to the undo facility in GLIMSLineData and keep selections and edits synchronized.

History:: 2005-07-23 Deborah Lee Soltesz - Added history and actions for Redo facility

What's New:: 2004-12-04 Lines and points associated with a glacier ID are displayed as selected in the GlacierIDDlg when selected on screen by the VectorEditor.

What's New:: 2005-07-23 Deborah Lee Soltesz Redo!!!

bool VectorEditor::isSelPoint	(	int &	iline,
		int &	inode
	)			`[protected]`

Answer to the question: Is the point (inode) in this line (iline) selected (in the current SelectionSet* mSelSet)?

Parameters:

	iline	Line to check for selected point. Value to match to SelObj.obj in SelectionSet* mSelSet. iline will be changed to either -1 (not found) or index in SelectionSet* mSelect where line is represented.
	inode	Point to check for selection status. Value to match to a node in SelObj.nodes (for SelObj.obj in SelectionSet* mSelSet matching the given line, iline). inode will be changed to either -1 (not found) or the index in SelObj.nodes where representing the point.

Returns:: if found, true if !found, false

void VectorEditor::viewSelChanged ( SelectionSet::SelBox & box ) [slot]

Sets vector data objects as selected.

Determines which vector data objects (points and/or lines) are inside the selection box (marquis, "dancing ants") the user has drawn, and sets those objects as selected. If the user has depressed the shift-key, the objects are added to the current list of selected objects, otherwise the list of selected objects is cleared before adding the current selection.

Parameters:

box

the selection box (marquis, "dancing ants") the user has drawn for the purpose of selecting vector objects on the screen to make them active for moving, deleting, etc.

VectorData* VectorEditor::mData [protected]

VectorData from active layer, consisting of std::vectors of Shapes, a SelectionSet, a Stack of undo's, an Image, and some other info. The VectorData will be GLIMSLineData or GLIMSGIDData, both of which ultimately inherit from the VectorData class.

For internal use only.

mData is retrieved from the active layer in VectorLayerSet mLayerSet using VectorLayer::getData during setActiveLayer call.
