#include <tk.h> Tk_ConfigureWindow(tkwin, valueMask, valuePtr) Tk_MoveWindow(tkwin, x, y) Tk_ResizeWindow(tkwin, width, height) Tk_MoveResizeWindow(tkwin, x, y, width, height) Tk_SetWindowBorderWidth(tkwin, borderWidth) Tk_ChangeWindowAttributes(tkwin, valueMask, attsPtr) Tk_SetWindowBackground(tkwin, pixel) Tk_SetWindowBackgroundPixmap(tkwin, pixmap) Tk_SetWindowBorder(tkwin, pixel) Tk_SetWindowBorderPixmap(tkwin, pixmap) Tk_SetWindowColormap(tkwin, colormap) Tk_DefineCursor(tkwin, cursor) Tk_UndefineCursor(tkwin)
Tk_Window tkwin (in) Token for window. unsigned int valueMask (in) OR-ed mask of values like CWX or CWBor- derPixel, indicating which fields of *valuePtr or *attsPtr Tk 1 Tk_ConfigureWindow(3) Tk Library Procedures 4.0 to use. XWindowChanges *valuePtr (in) Points to a structure containing new values for the con- figuration parameters selected by valueMask. Fields not selected by valueMask are ignored. int x (in) New x- coordinate for tkwin's top left pixel (including border, if any) within tkwin's parent. int y (in) New y- coordinate for tkwin's top left pixel (including border, if any) within tkwin's parent. int width (in) New width for tkwin (inte- rior, not including border). int height (in) New height for tkwin (interior, not including border). int borderWidth (in) New width for tkwin's Tk 2 Tk_ConfigureWindow(3) Tk Library Procedures 4.0 border. XSetWindowAttributes *attsPtr (in) Points to a structure containing new values for the attributes given by the valueMask argument. Attributes not selected by valueMask are ignored. unsigned long pixel (in) New back- ground or border color for window. Pixmap pixmap (in) New pixmap to use for back- ground or border of tkwin. WARN- ING: cannot necessarily be deleted immediately, as for Xlib calls. See note below. Colormap colormap (in) New colormap to use for tkwin. Tk_Cursor cursor (in) New cursor to use for tkwin. If None is specified, then tkwin will not have its own cur- sor; it will use the cur- sor of its parent. _________________________________________________________________ Tk 3 Tk_ConfigureWindow(3) Tk Library Procedures 4.0
These procedures are analogous to the X library procedures with similar names, such as XConfigureWindow. Each one of the above procedures calls the corresponding X procedure and also saves the configuration information in Tk's local structure for the window. This allows the information to be retrieved quickly by the application (using macros such as Tk_X and Tk_Height) without having to contact the X server. In addition, if no X window has actually been created for tkwin yet, these procedures do not issue X operations or cause event handlers to be invoked; they save the informa- tion in Tk's local structure for the window; when the win- dow is created later, the saved information will be used to configure the window. See the X library documentation for details on what these procedures do and how they use their arguments. In the procedures Tk_ConfigureWindow, Tk_MoveWindow, Tk_ResizeWindow, Tk_MoveResizeWindow, and Tk_SetWindowBorderWidth, if tkwin is an internal window then event handlers interested in configure events are invoked immediately, before the procedure returns. If tkwin is a top-level window then the event handlers will be invoked later, after X has seen the request and returned an event for it. Applications using Tk should never call procedures like XConfigureWindow directly; they should always use the corresponding Tk procedures. The size and location of a window should only be modified by the appropriate geometry manager for that window and never by a window itself (but see Tk_MoveToplevelWindow for moving a top-level window). You may not use Tk_ConfigureWindow to change the stacking order of a window (valueMask may not contain the CWSibling or CWStackMode bits). To change the stacking order, use the procedure Tk_RestackWindow. The procedure Tk_SetWindowColormap will automatically add tkwin to the TK_COLORMAP_WINDOWS property of its nearest top-level ancestor if the new colormap is different from that of tkwin's parent and tkwin isn't already in the TK_COLORMAP_WINDOWS property. BUGS Tk_SetWindowBackgroundPixmap and Tk_SetWindowBorderPixmap differ slightly from their Xlib counterparts in that the pixmap argument may not necessarily be deleted immediately Tk 4 Tk_ConfigureWindow(3) Tk Library Procedures 4.0 after calling one of these procedures. This is because tkwin's window may not exist yet at the time of the call, in which case pixmap is merely saved and used later when tkwin's window is actually created. If you wish to delete pixmap, then call Tk_MakeWindowExist first to be sure that tkwin's window exists and pixmap has been passed to the X server. A similar problem occurs for the cursor argument passed to Tk_DefineCursor. The solution is the same as for pixmaps above: call Tk_MakeWindowExist before freeing the cursor.
