If you have used the RealPlayer player, you must not be strange to its multi-mode display mode! RealPlayer has a normal and streamlined display mode. We sometimes want to implement a similar function on your own program interface, how do you implement it? Let's take the example of a multi-mode display program that uses VC6.0 to show you how it implements similar functions. As shown in the figure below: (Figure 1) Normal display mode; (Figure 2) Simple display mode, no view; (Figure 3), streamline display mode, only the tool bar.

Figure II
Figure three
Basic composition of ideas:
The implementation principle is simple, as long as the form size, the customer area size, the toolbar size, the state, the size, and the size of the title bar can be calculated based on different display modes, the height of different new forms (the key is To recall the height, width). Such as: Simple Display Mode (no visual mode), the width is unchanged, the height = Form height - the height of the customer area - status bar height - the height of the border. Streamline display mode (in toolbeans only), the width is unchanged, first hide menu, height = title bar height toolbar height border height can be used. Normal display mode, I don't want to say it! In fact, it is so simple, RealPlayer is a width and height change and calculates. This example only changes the height, the width is unchanged, but the basic principle is the same. Let's take a look at its code implementation!
Key code implementation:
I have made a mandate, this sample program can be implemented simply. When the nViewType is 0, for normal display mode, the pass value is 1, for the simple display mode, the pass value is 2, and the display mode is streamlined.
Void CMAINFRAME :: ViewMode (int NViewType)
{
CRECT ClientRect;
CRECT WINDOWRECT;
CRECT TOOLBARRECT;
CRECT STATUSBARRECT;
/ / Get the size of the form, customer zone and tools
WindowRect = m_windower;
ClientRect = m_client;
M_WndToolBar.GetWindower (& ToolbarRect);
// Get the size of the border and the title bar
Int borderheight = getSystemmetrics; SM_CYBORDER
INT CAPTIONHEIGHT = GetSystemMetrics (SM_CYCAPTION);
/ / Get the size of the status
CSTATUSBAR * PSTATUS = (cstatusbar *) AFXGetApp () -> m_pmainwnd-> getDescendantWindow (AFX_IDW_STATUS_BAR);
Pstatus-> getWindowRect (& statusbarRect);
// Stop the toolbar
DockControlbar (& M_WndToolbar);
INT CompactCX; // New Form Wide
Int Compactcy; // High new form
// Display in a variety of modes
Switch (nViewType) {
Case 0: // Normal display mode
{
// Display menu
IF (HMenu! = NULL)
:: SetMenu (M_HWND, HMENU);
// Display status strip
PStatus-> showwindow (sw_show);
// New form wide, high
Compactcx = windowRect.width ();
Compactcy = windowRect.height ();
}
Break;
Case 1: // Simple display mode
{
// Display menu
IF (HMenu! = NULL)
:: SetMenu (M_HWND, HMENU);
// Hidden status bar
PStatus-> showwindow (sw_hide);
// New form wide, high
Compactcx = windowRect.width ();
Compactcy = WindowRect.height () - ClientRect.Height () ToolbarRect.height () - BorderHeight;
}
Break;
Case 2: // Streamlined Mode
{
// Hide menu
HMENU = :: getMenu (m_hwnd);
:: SetMenu (M_HWND, NULL);
// Hidden status bar
PStatus-> showwindow (sw_hide);
// New form wide, high
Compactcx = windowRect.width ();
Compactcy = CaptionHeight ToolbarRect.Height () BorderHeight * 2;
}
Break;
}
/ / Set a new form display
SetwindowPos (& Wndtop, WindowRect.Left, WindowRect.top, Compactcx, Compactcy, SWP_SHOWINDOW);
}
The details of the specific implementation of the above part of the code can be done after downloading the instance code, and the source code can be carefully viewed (in detail).
