L_VOID LVectorWindow::SetToolType(uToolType)
|
L_UINT uToolType; |
/* the tool type */ |
Sets the tool type for the class object's window.
This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.
|
Parameter |
Description |
|
|
uToolType |
The tool type to be used by the vector window. Possible values are: |
|
|
|
Value |
Meaning |
|
|
TOOL_VECTOR_USERMODE |
user tool type (default). |
|
|
TOOL_VECTOR_SELECT |
select tool - allows the user to select individual objects in the vector. |
|
|
TOOL_VECTOR_PANIMAGE |
pan image tool - allows the user to pan the vector image by clicking a mouse button and dragging the mouse. The "pan cursor" will not appear if the image cannot be panned (i.e. - there are no scroll bars). If there are not scroll bars, press the PLUS key on the numeric key pad a few times to zoom until scroll bars appear. |
|
|
TOOL_VECTOR_ROTATE |
3d rotate tool - allows user to rotate the vector, or individual objects within a vector. |
Returns
None.
Comments
The vector window can automatically perform some functions. These include panning the vector, selecting individual components of a vector, and rotating the vector in 3 dimensions. The default setting for an LVectorWindow object is TOOL_VECTOR_USERMODE.
If the tool type is TOOL_VECTOR_SELECT, you can do the following:
Left-click and drag the mouse to
define a rectangle. All objects in the defined rectangle are selected.
Right-click and drag the mouse to
define a rectangle. All objects in the defined rectangle are un-selected.
Double clicking the left mouse button
automatically selects all objects in the vector. NOTE: If creating the
LVectorWindow as a window, the window style must include the CS_DBLCLKS
style to receive double click messages.
Double clicking the right mouse button
automatically un-selects all objects in the vector. NOTE: If creating
the LVectorWindow as a window, the window style must include the CS_DBLCLKS
style to receive double click messages.
When using the vector dialogs, only the currently selected objects are affected. If the SelectedOnly state is set to TRUE (LVectorWindow::GetSelectedOnly, LVectorWindow::SetSelectedOnly), then only selected objects will be scaled. If the SelectedOnly state is set to FALSE, then ALL objects are scaled.
If the tool type is TOOL_VECTOR_ROTATE, you can do the following:
Left-click and drag the mouse. If
you move the mouse vertically (up and down), the vector image rotates
up and down along an imaginary X-axis which passes horizontally through
the vector. If you move the mouse horizontally (left and right), the vector
image rotates left and right along an imaginary Y-axis which passes vertically
through the vector. Dragging the mouse at an angle results in a combination
of these rotations.
Right-click and drag the mouse. The
"rotate-Z" cursor appears. Dragging the mouse causes the vector
to rotate in the XY plane (the plane that corresponds to the screen) along
an imaginary Z-axis which passes through the center of the window.
