Vector Tools

Start with the project you created in Vector Load and Save.

Take the following steps to add panning, selecting, and rotating capabilities:

1.

In the project workspace, click on the Resource View tab and then click to open the "Tutorial resouces" branch.

2.

Click to open the "Menu" branch and double click IDR_TutorialTYPE.

3.

Add a menu item called "Tools" between the Edit and View items.

4.

Create this Menu structure under the Tools Menu item:

 

&None with ID = ID_TOOLS_NONE 
&Pan with ID = ID_TOOLS_PAN 
&Select with ID = ID_TOOLS_SELECT 
&Rotate with  ID = ID_TOOLS_ROTATE

5.

Select View->ClassView.

6.

Right click on CTutorialDoc and select properties.

7.

In the properties window select Events shortcut.

8.

Select ID_TOOLS_NONE then COMMAND then add OnToolsNone

9.

Repeat steps 5 6, and select ID_TOOLS_NONE then UPDATE_COMMAND_UI then add OnUpdateToolsNone

10.

Repeat steps 5 through 9 for ID_TOOLS_PAN, ID_TOOLS_ROTATE, ID_TOOLS_SELECT.

11.

Add the following code for the eight newly created functions:

 

void CTutorialDoc::OnToolsNone() 
{ 
   m_pVectorWindow->SetToolType (TOOL_VECTOR_USERMODE); 
} 
void CTutorialDoc::OnUpdateToolsNone(CCmdUI* pCmdUI) 
{ 
   pCmdUI->SetCheck (m_pVectorWindow->GetToolType () == TOOL_VECTOR_USERMODE); 
} 
void CTutorialDoc::OnToolsPan() 
{ 
   m_pVectorWindow->SetToolType (TOOL_VECTOR_PANIMAGE); 
} 
void CTutorialDoc::OnUpdateToolsPan(CCmdUI* pCmdUI) 
{ 
   pCmdUI->SetCheck(m_pVectorWindow->GetToolType () == TOOL_VECTOR_PANIMAGE); 
} 
void CTutorialDoc::OnToolsSelect() 
{ 
   m_pVectorWindow->SetToolType (TOOL_VECTOR_SELECT); 
} 
void CTutorialDoc::OnUpdateToolsSelect(CCmdUI* pCmdUI) 
{ 
   pCmdUI->SetCheck(m_pVectorWindow->GetToolType () == TOOL_VECTOR_SELECT); 
} 
void CTutorialDoc::OnToolsRotate() 
{ 
   m_pVectorWindow->SetToolType (TOOL_VECTOR_ROTATE); 
} 
void CTutorialDoc::OnUpdateToolsRotate(CCmdUI* pCmdUI) 
{ 
   pCmdUI->SetCheck(m_pVectorWindow->GetToolType () == TOOL_VECTOR_ROTATE); 
}

12.

Compile and run the program. Load an image. Hit the "+" key on the numeric keypad several times to zoom on the image. Select the Pan tool. A hand appears. Click anywhere on the image and drag. Now choose the Select tool. Click and drag on the image to select objects. Left-double click to select all objects. Right double-click to unselect all objects. Choose the Rotate tool. Left click and drag to rotate about the x and y axes. Right click and drag to rotate along the Z-axis.
