When a grab is set on a particular window +in a Tk application, mouse and keyboard events can only be received by +that window and its descendants. Mouse and keyboard events for +windows outside the tree rooted at \fItkwin\fR will be redirected to +\fItkwin\fR. If the grab is global, then all mouse and keyboard +events for windows outside the tree rooted at \fItkwin\fR (even those +intended for windows in other applications) will be redirected to +\fItkwin\fR. If the grab is application local, only mouse and +keyboard events intended for a windows within the same application +(but outside the tree rooted at \fItkwin\fR) will be redirected. + +.PP +\fBTk_Grab\fR sets a grab on a particular window. \fITkwin\fR +specifies the window on whose behalf the pointer is to be grabbed. +\fIGrabGlobal\fR indicates whether the grab should be global or +application local; if it is non-zero, it means the grab should be +global. Normally, \fBTk_Grab\fR returns TCL_OK; if an error occurs +and the grab cannot be set, TCL_ERROR is returned and an error message +is left if \fIinterp\fR's result. Once this call completes +successfully, no window outside the tree rooted at \fItkwin\fR will +receive pointer- or keyboard-related events until the next call to +Tk_Ungrab. If a previous grab was in effect within the application, +then it is replaced with a new one. + +.PP +\fBTcl_Ungrab\fR releases a grab on the mouse pointer and keyboard, if +there is one set on the window given by \fItkwin\fR. Once a grab is +released, pointer and keyboard events will start being delivered to +other windows again. + +.SH KEYWORDS +grab, window diff --git a/unix/mkLinks b/unix/mkLinks index eba719a..203b872 100644 --- a/unix/mkLinks +++ b/unix/mkLinks @@ -63,6 +63,14 @@ if test -r GetFont.3; then rm -f Tk_AllocFontFromObj.3 ln GetFont.3 Tk_AllocFontFromObj.3 fi +if test -r Grab.3; then + rm -f Tk_Grab.3 + ln Grab.3 Tk_Grab.3 +fi +if test -r Grab.3; then + rm -f Tk_Ungrab.3 + ln Grab.3 Tk_Ungrab.3 +fi if test -r WindowId.3; then rm -f Tk_Attributes.3 ln WindowId.3 Tk_Attributes.3 |
