Additional options, described above, may be specified on the command line or in the option database to configure aspects of the Tree widget such as its cursor and relief. .PP The Tree widget can be used to display hierachical data in a tree form. The user can adjust the view of the tree by opening or closing parts of the tree. .PP To display a static tree structure, you can add the entries into the \fBhlist\fR subwidget and hide any entries as desired. Then you can call the \fBautosetmode\fR method. This will set up the Tree widget so that it handles all the \fIopen\fR and \fIclose\fR events automatically. '\"(TODO add an example). .PP The above method is not applicable if you want to maintain a dynamic tree structure, i.e, you do not know all the entries in the tree and you need to add or delete entries subsequently. To do this, you should first create the entries in the \fBhlist\fR subwidget. Then, use the setmode method to indicate the entries that can be opened or closed, and use the \fB\-opencmd\fR and \fB \-closecmd\fR options to handle the opening and closing events. '\"(TODO add an example). '\" '\" '\"---------------------------------------------------------------------- .SH WIDGET COMMANDS .PP '\" The \fBtixTree\fR command creates a new Tcl command whose name is the same as the path name of the Tree's window. This command may be used to invoke various operations on the widget. It has the following general form: '\" .RS .CS '\" \fIpathName option \fR?\fIarg arg ...\fR? .CE .RE '\" \fIPathName\fR is the name of the command, which is the same as the Tree widget's path name. \fIOption\fR and the \fIarg\fRs determine the exact behavior of the command. The following commands are possible for Tree widgets: '\" .TP \fIpathName \fBautosetmode\fR '\" This command calls the \fBsetmode\fR method for all the entries in this Tree widget: if an entry has no child entries, its mode is set to \fBnone\fR. Otherwise, if the entry has any hidden child entries, its mode is set to \fBopen\fR; otherwise its mode is set to \fBclose\fR. '\" .TP \fIpathName \fBcget\fR \fIoption\fR '\" Returns the current value of the configuration option given by \fIoption\fR. \fIOption\fR may have any of the values accepted by the \fBtixTree\fR command. '\" '\" .TP \fIpathName \fBclose \fIentryPath\fR '\" Close the entry given by \fIentryPath\fR if its \fImode\fR is \fBclose\fR. '\" '\" .TP \fIpathName \fBconfigure\fR ?\fIoption\fR? \fI?value option value ...\fR? '\" Query or modify the configuration options of the widget. If no \fIoption\fR is specified, returns a list describing all of the available options for \fIpathName\fR (see \fBTk_ConfigureInfo\fR for information on the format of this list). If \fIoption\fR is specified with no \fIvalue\fR, then the command returns a list describing the one named option (this list will be identical to the corresponding sublist of the value returned if no \fIoption\fR is specified). If one or more \fIoption\-value\fR pairs are specified, then the command modifies the given widget option(s) to have the given value(s); in this case the command returns an empty string. \fIOption\fR may have any of the values accepted by the \fBtixTree\fR command. '\" '\" .TP \fIpathName \fBgetmode \fIentryPath\fR '\" Returns the current \fImode\fR of the entry given by \fIentryPath\fR. '\" .TP \fIpathName \fBopen \fIentryPath\fR '\" Open the entry givaen by \fIentryPath\fR if its \fImode\fR is \fBopen\fR. '\" .TP \fIpathName \fBsetmode \fI entryPath mode\fR '\" This command is used to indicate whether the entry given by \fIentryPath\fR has children entries and whether the children are visible. \fImode\fR must be one of \fBopen\fR, \fBclose\fR or \fBnone\fR. If \fImode\fR is set to \fBopen\fR, a (+) indicator is drawn next the the entry. If \fImode\fR is set to \fBclose\fR, a (-) indicator is drawn next the the entry. If \fImode\fR is set to \fBnone\fR, no indicators will be drawn for this entry. The default \fImode\fR is none. The \fBopen\fR mode indicates the entry has hidden children and this entry can be opened by the user. The \fBclose\fR mode indicates that all the children of the entry are now visible and the entry can be closed by the user. '\" .TP \fIpathName \fBsubwidget \fI name ?args?\fR '\" When no options are given, this command returns the pathname of the subwidget of the specified name. When options are given, the widget command of the specified subwidget will be called with these options. '\" '\" '\" '\"---------------------------------------------------------------------- .SH BINDINGS .PP '\" The basic mouse and keyboard bindings of the Tree widget are the same as the bindings of the HList widget. In addition, the entries can be opened or closed under the following conditions: '\" .IP [1] If the \fImode\fR of the entry is \fBopen\fR, it can be opened by clicking on its (+) indicator or double-clicking on the entry. '\" .IP [2] If the \fImode\fR of the entry is \fBclose\fR, it can be closed by clicking on its (-) indicator or double-clicking on the entry.
