For -example, many transient windows would like to display a ``drop shadow'' to -give the illusion of 3 dimensions. As another example, some user interface -style guides call for buttons with rounded corners; the full simulation of a -nonrectangular shape, particularly with respect to event distribution and -cursor shape, is not possible within the core X protocol. As a final -example, round clocks and nonrectangular icons are desirable visual addition -to the desktop. -.LP -This extension provides mechanisms for changing both the visible and interactive shape of a -window to arbitrary, possibly disjoint, nonrectangular forms. The intent -of the extension is to supplement the existing semantics, not replace them. -In particular, it is desirable for clients that are unaware of the -extension to still be able to cope reasonably with shaped windows. For -example, window managers should still be able to negotiate screen -real estate in rectangular pieces. Toward this end, any shape specified for -a window is clipped by the bounding rectangle for the window as specified by -the window's geometry in the core protocol. An expected convention would be -that client programs expand their shape to fill the area offered by the -window manager. -.NH 1 -Description -.LP -Each window (even with no shapes specified) is defined by three regions: the -\fIbounding region\fP, the \fIclip region\fP and the \fIinput region\fP. The bounding region is the area of the -parent window that the window will occupy (including border). The clip region -is the subset of the bounding region that is available for subwindows and -graphics. The area between the bounding region and the clip region is defined -to be the border of the window. The input region is the subset of the -bounding region that can ``contain'' the pointer. -.LP -A nonshaped window will have a bounding region that is a rectangle -spanning the window, including its border; the clip region will be a rectangle -filling the inside dimensions (not including the border); the input -region will match the bounding region. In this document, -these areas are referred to as the \fIdefault bounding region\fP, the -\fIdefault clip region\fP and the \fIdefault input region\fP. For a window with inside size of \fIwidth\fP by -\fIheight\fP and border width \fIbwidth\fP, the default bounding, clip -and input -regions are the rectangles (relative to the window origin): -.LP -.sM -.Ds 0 -bounding.x = -\fIbwidth\fP -bounding.y = -\fIbwidth\fP -bounding.width = \fIwidth\fP + 2 * \fIbwidth\fP -bounding.height = \fIheight\fP + 2 * \fIbwidth\fP - -clip.x = 0 -clip.y = 0 -clip.width = \fIwidth\fP -clip.height = \fIheight\fP - -input.x = -\fIbwidth\fP -input.y = -\fIbwidth\fP -input.width = \fIwidth\fP + 2 * \fIbwidth\fP -input.height = \fIheight\fP + 2 * \fIbwidth\fP - -.De -.LP -.eM -This extension allows a client to modify any combination of the bounding, -clip or input regions by specifying new regions that combine with the default -regions. These new regions are called the \fIclient bounding region\fP, -the \fIclient clip region\fP and the \fIclient input region\fP. They are specified relative to the origin of -the window and are always defined by offsets relative to the window origin -(that is, region adjustments are not required when the window is moved). -Three mechanisms for specifying regions are provided: a list of rectangles, -a bitmap, and an existing bounding or clip region from a window. This is -modeled on the specification of regions in graphics contexts in the core -protocol and allows a variety of different uses of the extension. -.LP -When using an existing window shape as an operand in specifying a new shape, -the client region is used, unless none has been set, in which case the -default region is used instead. -.LP -The \fIeffective bounding region\fP of a window is defined to be the intersection of -the client bounding region with the default bounding region. Any portion of -the client bounding region that is not included in the default bounding -region will not be included in the effective bounding region on the screen. -This means that window managers (or other geometry managers) used to dealing -with rectangular client windows will be able to constrain the client to a -rectangular area of the screen. -.LP -Construction of the effective bounding region is dynamic; the client bounding -region is not mutated to obtain the effective bounding region. If a client -bounding region is specified that extends beyond the current default bounding -region, and the window is later enlarged, the effective bounding region will -be enlarged to include more of the client bounding region. -.LP -The \fIeffective clip region\fP of a window is defined to be the intersection of the -client clip region with both the default clip region and the client bounding -region. Any portion of the client clip region that is not included in both -the default clip region and the client bounding region will not be included in -the effective clip region on the screen. -.LP -Construction of the effective clip region is dynamic; the client clip region is -not mutated to obtain the effective clip region. If a client clip region is -specified that extends beyond the current default clip region and the -window or its bounding region is later enlarged, the effective clip region will -be enlarged to include more of the client clip region if it is included in -the effective bounding region. -.LP -The border of a window is defined to be the difference between the effective -bounding region and the effective clip region. If this region is empty, no -border is displayed. If this region is nonempty, the border is filled -using the border-tile or border-pixel of the window as specified in the core -protocol. Note that a window with a nonzero border width will never be able -to draw beyond the default clip region of the window. Also note that a zero -border width does not prevent a window from having a border, since the clip -shape can still be made smaller than the bounding shape. -.LP -All output to the window and visible regions of any subwindows will be -clipped to the effective clip region. The server must not retain window -contents beyond the effective bounding region with backing store. The window's -origin (for graphics operations, background tiling, and subwindow placement) -is not affected by the existence of a bounding region or clip region. -.LP -The \fIeffective input region\fP of a window is defined to be the intersection of the -client input region with both the default input region and the client bounding -region. Any portion of the client input region that is not included in both -the default input region and the client bounding region will not be included in -the effective input region on the screen. -.LP -Construction of the effective input region is dynamic; the client input region is -not mutated to obtain the effective input region. If a client input region is -specified that extends beyond the current default input region and the -window or its bounding region is later enlarged, the effective input region will -be enlarged to include more of the client input region if it is included in -the effective bounding region. -.LP -Areas that are inside the default bounding region but outside the effective -bounding region are not part of the window; these areas of the screen will -be occupied by other windows. Input events that occur within the default -bounding region but outside the effective bounding region will be delivered as -if the window was not occluding the event position. Events that occur in -a nonrectangular border of a window will be delivered to that window, just -as for events that occur in a normal rectangular border. -.LP -An -.PN InputOnly -window can have its bounding or input region set, but it is a -.PN Match -error to attempt to set a clip region on an -.PN InputOnly -window or to specify its clip region as a source to a request -in this extension. -.LP -The server must accept changes to the clip and input regions of a root window, but -the server is permitted to ignore requested changes to the bounding region -of a root window. If the server accepts bounding region changes, the contents -of the screen outside the bounding region are implementation dependent. -.NH 1 -Types -.LP -The following types are used in the request and event definitions in -subsequent sections. -.LP -SHAPE_KIND: -.Pn { Bounding , -.PN Clip , -.PN Input } -.LP -SHAPE_OP: -.Pn { Set , -.PN Union , -.PN Intersect , -.PN Subtract , -.PN Invert } -.LP -.PN Set -indicates that the region specified as an explicit source in the request is stored -unaltered as the new destination client region. -.PN Union -indicates that the source and destination regions are unioned together to produce -the new destination client region. -.PN Intersect -indicates that the source and destination regions are intersected together to -produce the new destination client region. -.PN Subtract -indicates that the source region is subtracted from the destination region to -produce the new destination region. -.PN Invert -indicates that the destination region is subtracted from the source region to -produce the new destination region. -.NH 1 -Requests -.LP -.sM -.PN "ShapeQueryVersion" -.LP - => -.IP -majorVersion: CARD16 -.br -minorVersion: CARD16 -.LP -.eM -This request can be used to ensure that the server version of the SHAPE -extension is usable by the client.
