- TAnimateCtrl, an Introduction
- =============================
- TAnimateCtrl encapsulates the animation control fo the Common
- Control library. The control is a window that silently displays
- an AVI (Audio Video Interleaved) clip.
- NOTE: The animation control can only play silent clips from an
- uncompressed .AVI file or from an .AVI file that was compressed
- using run-length encoding (RLE).
-
-
- Creating a TAnimateCtrl Object
- ==============================
- TAnimateCtrl provides two constructors:
- 1. TAnimateCtrl(parent, id, x, y, w, h, module);
- 2. TAnimateCtrl(parent, resourceId, module);
-
- The first one can be used to create a brand new control. For
- example, you may use the following syntax within the constructor
- of a parent window:
-
- TClientWindow::TClientWindow(TWindow* parent) : TWindow(parent)
- {
- AnimateCtrl = new TAnimateCtrl(this, 0x100, 5, 10, 50, 60);
- };
-
- The above snippet instruct ObjectWindows to create an animation
- control with the ID of 0x100, at location (5,10), 50 pixels wide
- and 60 pixels high within the client area of the TClientWindow
- window.
-
- The other constructor of the TAnimateCtrl class is used to alias
- an animation control which is part of a dialog resource. The following
- resource definition illustrates a dialog containing an animation
- control:
-
- IDD_ANIMATE DIALOG 45, 56, 176, 99
- STYLE DS_MODALFRAME | WS_POPUP | WS_VISIBLE | WS_CAPTION | WS_SYSMENU
- CAPTION "Animation Dialog"
- {
- CONTROL "Sample_Avi", IDC_ANIMATE, "SysAnimate32", ACS_CENTER | ACS_TRANSPARENT | WS_CHILD | WS_VISIBLE | WS_BORDER, 16, 10, 145, 61
- }
-
- The following snippet illustrates how to alias an animation
- control within a TDialog-derived class' constructor:
-
- TAnimDialog::TAnimDialog(TWindow* parent, TResId res)
- :TDialog(parent, res)
- {
- AnimCtrl = new TAnimateCtrl(this, IDC_ANIMATE);
- }
-
-
- Using the TAnimateCtrl Object
- =============================
- After creating an animation control you can invoke the 'Open'
- method to open an AVI clip and load it in memory. The following
- code illustrates:
-
- AnimateCtrl->Open(MAKEINTRESOURCE(SAMPLE_ONE));
-
- NOTE: The parameter to the 'Open' method can contain the path to
- an .AVI file or the name of an AVI resource.
-
- The 'Play' method of TAnimateCtrl plays the current AVI clip in
- the animation window. Note that the control plays the clip in
- the background while the thread continues executing.
-
- The 'Seek' method allows you to seek to a particular frame of
- the current .AVI clip while the 'Stop' method stops playing any
- .AVI clip.
-
-
- Additional Information
- ======================
- 1. The specified caption of the control may contain the name of
- an .AVI resource to be opened automatically be the control.
-
- 2. Passing '-1' as the third argument to the 'Play' method
- instructs the control to replay the clip indefinitely.
