Tk_DefineCursor(tkwin, cursor)
Tk_UndefineCursor(tkwin)

ARGUMENTS

Tk_Windowtkwin(in) Token for window. 

unsigned intvalueMask(in) OR-ed mask of values like CWX or CWBorderPixel, indicating which fields of ∗valuePtr or ∗attsPtr to use. 

XWindowChanges∗valuePtr(in) Points to a structure containing new values for the configuration parameters selected by valueMask.  Fields not selected by valueMask are ignored. 

intx(in) New x-coordinate for tkwin’s top left pixel (including border, if any) within tkwin’s parent. 

inty(in) New y-coordinate for tkwin’s top left pixel (including border, if any) within tkwin’s parent. 

unsigned intwidth(in) New width for tkwin (interior, not including border). 

unsigned intheight(in) New height for tkwin (interior, not including border). 

unsigned intborderWidth(in) New width for tkwin’s 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 longpixel(in) New background or border color for window. 

Pixmappixmap(in) New pixmap to use for background or border of tkwin.  WARNING: cannot necessarily be deleted immediately, as for Xlib calls.  See note below. 

Cursorcursor(in) New cursor to use for tkwin.  If None is specified, then tkwin will not have its own cursor;  it will use the cursor of its parent. 

DESCRIPTION

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 information in Tk’s local structure for the window;  when the window 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 a child window (i.e. it was created with a call to Tk_CreateChildWindow), then event handlers interested in configure events are invoked immediately.  If tkwin isn’t an internal 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. 
 

BUGS

Tk_SetWindowBackgroundPixmap and Tk_SetWindowBorderPixmap differ slightly from their Xlib counterparts in that the pixmap argument may not necessarily be deleted immediately 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.
