Type
of arrangement for icons or bitmaps.
Specify one of the following arrangement types:
CMA_ARRANGESTANDARD
Standard arrangement.
Icons are arranged at the top of the window, starting at the upper left-hand
corner. This value is set to zero to provide compatibility with existing
applications.
CMA_ARRANGEGRID
Grid arrangement.
Icons are arranged in a grid of equal-size squares in the container window.
The grid pattern can be defined as the perimeter, left, right, top, or bottom
of the window. It also can be user-defined.
CMA_ARRANGESELECTED
ulArrangeFlags (ULONG)
Flags for arrangement type specified in ultype.
CMA_ARRANGESTANDARD
If the arrangement type is
CMA_ARRANGESTANDARD, this value is NULL.
CMA_ARRANGEGRID
If the arrangement type is CMA_ARRANGEGRID, specify
one of the following arrangement patterns:
CMA_PERIMETER
Icons are arranged along the top,
left and right side of the window, leaving the middle unoccupied.
CMA_LEFT
Icons are arranged starting at the upper left corner
of the window and proceeding top-to-bottom, left-to-right.
CMA_RIGHT
Icons are arranged starting at the upper right corner
of the window, and proceeding top-to-bottom, right-to-left.
CMA_TOP
Icons are arranged at the top of the window. The
difference between this and the standard arrangement is that positioning
is according to grid square size, not tile size. (An icon's tile size is
the rectangle that encompasses both icon and text.)
CMA_BOTTOM
Icons are arranged, starting at the lower left corner
and proceeding left-to-right, bottom-to-top.
CMA_USER
The application provides the user with a means of
specifying which squares are to be occupied and which are not. The CM_SETGRIDINFO
message marks each grid square as available or unavailable for an icon.
The current grid information can be obtained at any time by using the CM_QUERYGRIDINFO
message.
CMA_ARRANGESELECTED
If the arrangement type is CMA_ARRANGESELECTED,
specify one of the following orientations:
CMA_HORIZONTAL
Orient selected icons horizontally.
CMA_VERTICAL
Orient selected
icons vertically.
When the container receives a
message indicating a selected arrangement is desired, it goes into "Selected
Arrange" mode. The mouse is captured and the pointer changes to indicate
the orientation of the arrangement selection in progress (horizontal or
vertical). When the user presses mouse button 1 over an area in the container
window, the icons are immediately positioned at that point, and the container
ends the selected range mode and releases the mouse capture. If the current
view is CV_ICON, the selected icons are arranged starting at the precise
point where the user clicked the mouse. If the current view is CV_GRID,
the selected icons are arranged starting at the grid square closest to the
point where the user clicked the mouse.
