Show in webframe

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.
