Detailed Description

Allows the user to change the yaw, pitch and roll of a connected component of images by dragging them in the fast preview.

If there are multiple components under the pointer when the user begins to drag, the lowest number one is chosen, since it is drawn on top.

Modifiers	Variables changed
none	yaw and pitch
shift	yaw or pitch, depending on biggest difference.
control	roll

You can also change only roll by using the secondary mouse button (if there is one).

Reasoning: control click on mac is equivalent right click on other platforms, no modifiers should be close to old behaviour (where no modifiers were used), alt moves windows on some window managers, leaving shift as the only common modifier suitable for constrained drag.

Member Function Documentation

void DragTool::Activate ( )

virtual

Switch on a tool.

Inherited classes also register events they want to respond to with the PreviewToolHelper. As events are lost when the tool is deactivated without notification to the PreviewTool, things from the last activation can be cleaned up here too.

Implements Tool.

void DragTool::MouseMoveEvent	(	double	x,

		wxMouseEvent &	e
	)

virtual

Notify when the mouse pointer has moved over the panorama preview.

The coordinates are in the space of the panorama output at full size, with no output cropping.

Parameters

x	The horizontal position of the mouse pointer in panorama pixels.
y	The vertical position of the mouse pointer in panorama pixels.
e	The event created by wxWidgets.
