LVectorWindow::SetToolType

Summary

Sets the tool type for the class object's window.

This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.

Syntax

#include "ltwrappr.h"

L_INT LVectorWindow::SetToolType(uToolType)

Parameters

L_UINT 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.

Example

Assumes pVectorWindow points to a valid LVectorWindow object.

L_INT LVectorWindow__SetToolTypeExample(HWND hWndParent, LVectorWindow *pVectorWindow, L_UINT uToolType) 
{ 
   L_TCHAR*    lpszMsg = NULL; 
 
   pVectorWindow->SetToolType(uToolType); 
 
   switch (uToolType) 
   { 
   case TOOL_VECTOR_USERMODE: 
      lpszMsg = TEXT("Current tool: TOOL_VECTOR_USERMODE"); 
      break; 
   case TOOL_VECTOR_SELECT: 
      lpszMsg = TEXT("Current tool: TOOL_VECTOR_SELECT"); 
      break; 
   case TOOL_VECTOR_PANIMAGE: 
      lpszMsg = TEXT("Current tool: TOOL_VECTOR_PANIMAGE"); 
      break; 
   case TOOL_VECTOR_ROTATE: 
      lpszMsg = TEXT("Current tool: TOOL_VECTOR_ROTATE"); 
      break; 
   } 
    ::SetWindowText(hWndParent, lpszMsg); 
 
    return SUCCESS; 
}
