CBCGPChartLegendCtrl

Detailed Description

The CBCGPChartLegendCtrl implements the functionality of a visual control (CBCGPVisualCtrl) that hosts a CBCGPChartLegendVisualObject.

You can use this control to place an advanced legend on a dialog or embed it into a dockable pane.

The following code illustrates how to embed a legend into dockable pane:

Copy

class CMyDockingPane : public CBCGPDockingControlBar

{

public:

CMyDockingPane();

// Attributes

public:

CBCGPChartLegendCtrl m_legend;

// other code.....

afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);

afx_msg void OnSize(UINT nType, int cx, int cy);

AFX_MSG DECLARE_MESSAGE_MAP()

};

int CMyDockingPane::OnCreate(LPCREATESTRUCT lpCreateStruct)

{

if (CBCGPDockingControlBar::OnCreate(lpCreateStruct) == -1)

return -1;

// note that rectangle must not be empty

m_legend.Create(CRect(0, 0, 1, 1), this, 0);

return 0;

}

void CMyDockingPane::OnSize(UINT nType, int cx, int cy)

{

CBCGPDockingControlBar::OnSize(nType, cx, cy);

// Legend control should cover a whole client area:

m_legend.SetWindowPos (NULL, -1, -1, cx, cy, SWP_NOMOVE | SWP_NOACTIVATE | SWP_NOZORDER);

}
