SAMPLE: Application Splits a Window into Two Panes

The information in this article applies to:

SUMMARY

SPLITWIN is a file in the Microsoft Software Library that demonstrates splitting a window into two panes using the mouse or keyboard. Each pane can be scrolled independently in the vertical direction. Scrolling the lower child horizontally, however, causes the upper child to scroll by the same amount.

MORE INFORMATION

The SPLITWIN sample creates a frame window that has a child window. The child window fills the client area of the frame window. When the user splits the window, SPLITWIN creates a second child window. The two child windows are sized according to the position of the split bar.

The user can change the position of the split bar using either the mouse or the arrow keys. After the window is split, it can be restored to its original state by dragging the split bar off the frame window or by selecting a position that does not provide enough room to create the second window.

When the user clicks the mouse button in the split bar, SPLITWIN starts a PeekMessage() loop that processes mouse and keyboard messages. The PatBlt() function updates the position of the split bar as it is dragged.
