If the +insert point is already at the end or beginning of the line then no action is taken. +.IP next-line(\|) 2.0i +.br +.ns +.IP previous-line(\|) 2.0i +These actions move the insert point up or down one line. If the insert +point is currently N characters from the beginning of the line then it +will be N characters from the beginning of the next or previous line. +If N is past the end of the line, the insert point is placed at the end +of the line. +.IP next-page(\|) 2.0i +.br +.ns +.IP previous-page(\|) 2.0i +These actions move the insert point up or down one page in the file. +One page is defined as the current height of the text widget. The +insert point is always placed at the first character of the top line by +this action. +.IP beginning-of-file(\|) 2.0i +.br +.ns +.IP end-of-file(\|) 2.0i +These actions place the insert point at the beginning or end of the +current text buffer.

It +will then begin a selection at this location. If many of these +selection actions occur quickly in succession then the selection count +mechanism will be invoked (see the section titled \fBText Selections for +Application Programmers\fP for details). +.IP select-adjust(\|) 2.0i +This action allows a selection started with the \fIselect-start\fP +action to be modified, as described above. +.IP select-end(\fIname\fP[,\fIname\fP,...]) 2.0i +This action ends a text selection that began with the \fIselect-start\fP +action, and asserts ownership of the selection or selections specified. +A \fIname\fP can be a selection (e.g., \fBPRIMARY\fP) or a cut buffer +(e.g., \fBCUT_BUFFER0\fP). Note that case is important. If no +\fInames\fP are specified, \fBPRIMARY\fP is asserted. +.IP extend-start(\|) 2.0i +This action finds the nearest end of the current selection, and moves it +to the current pointer location (if triggered by a button event) or text +cursor location (if triggered by a key event). +.IP extend-adjust(\|) 2.0i +This action allows a selection started with an \fIextend-start\fP action +to be modified. +.IP extend-end(\fIname\fP[,\fIname\fP,...]) 2.0i +This action ends a text selection that began with the \fIextend-start\fP +action, and asserts ownership of the selection or selections specified. +A \fIname\fP can be a selection (e.g. \fBPRIMARY\fP) or a cut buffer +(e.g \fBCUT_BUFFER0\fP). Note that case is important. If no names are +given, \fBPRIMARY\fP is asserted. +.IP insert-selection(\fIname\fP[,\fIname\fP,...]) 2.0i +This action retrieves the value of the first (left-most) named selection +that exists or the cut buffer that is not empty and inserts it into the +Text widget at the current insert point location. A \fIname\fP can be a +selection (e.g. \fBPRIMARY\fP) or a cut buffer (e.g \fBCUT_BUFFER0\fP). +Note that case is important. +.NH 3 +The New Line Actions +.LP +.sp +.IP newline-and-indent(\|) 2.0i +This action inserts a newline into the text and adds spaces to +that line to indent it to match the previous line. +.IP newline-and-backup(\|) 2.0i +This action inserts a newline into the text \fIafter\fP the insert point. +.IP newline(\|) 2.0i +This action inserts a newline into the text \fIbefore\fP the insert point. +.NH 3 +Kill and Actions +.LP +.sp +.IP kill-word(\|) 2.0i +.br +.ns +.IP backward-kill-word(\|) 2.0i +These actions act exactly like the \fIdelete-next-word\fP and +\fIdelete-previous-word\fP actions, but they stuff the word that was +killed into the kill buffer (\fBCUT_BUFFER_1\fP). +.IP kill-selection(\|) 2.0i +This action deletes the current selection and stuffs the deleted text into +the kill buffer (\fBCUT_BUFFER_1\fP). +.IP kill-to-end-of-line(\|) 2.0i +This action deletes the entire line to the right of the insert point position, +and stuffs the deleted text into the kill buffer (\fBCUT_BUFFER_1\fP). +.IP kill-paragraph(\|) 2.0i +This action deletes the current paragraph, if between paragraphs it deletes +the paragraph above the insert point, and stuffs the deleted text into +the kill buffer (\fBCUT_BUFFER_1\fP). +.IP kill-to-end-of-paragraph(\|) 2.0i +This action deletes everything between the current insert point location and +the next paragraph boundary, and stuffs the deleted text into the kill +buffer (\fBCUT_BUFFER_1\fP). +.NH 3 +Miscellaneous Actions +.LP +.sp 1 +.IP redraw-display(\|) 2.0i +This action recomputes the location of all the text lines on the +display, scrolls the text to vertically center the line containing the insert point +on the screen, clears the entire screen, and redisplays it. +.IP insert-file([\fIfilename\fP]) 2.0i +This action activates the insert file popup. The \fIfilename\fP +option specifies the default filename to put in the filename buffer of +the popup. If no \fIfilename\fP is specified the buffer is empty +at startup. +.IP insert-char(\|) 2.0i +This action may only be attached to a key event. When the +\fBinternational\fP resource is \fBfalse\fP, this action +calls XLookupString to translate the event into a (rebindable) Latin-1 +character (sequence) and inserts it into the text at the +insert point. When the \fBinternational\fP resource is \fBtrue\fP, +characters are passed to the input method via XwcLookupString, and any +committed string returned is inserted into the text at the insert point. +.IP insert-string(\fIstring\fP[,\fIstring\fP,...]) 2.0i +This action inserts each \fIstring\fP into the text +at the insert point location. Any \fIstring\fP +beginning with the characters "0x" followed by an even +number of hexadecimal digits is +interpreted as a hexadecimal constant and the +corresponding string is inserted instead. This +hexadecimal string may represent up to 50 8-bit characters. + When the\fBinternational\fP resource is +\fBtrue\fP, a hexadecimal string is intrepeted as +being in a multi-byte encoding, and a hexadecimal +or regular string will result in an error message +if it is not legal in the current locale. +.IP display-caret(\fIstate\fP,\fIwhen\fP) 2.0i +This action allows the insert point to be turned on and off. +The \fIstate\fP argument specifies the desired state of the insert point. +This value may be any of the string +values accepted for Boolean resources (e.g. \fBon\fP, \fBTrue\fP, +\fBoff\fP, \fBFalse\fP, etc.). If no arguments are specified, the +default value is \fBTrue\fP. +The \fIwhen\fP argument specifies, for \fBEnterNotify\fP or \fBLeaveNotify\fP +events whether or not the focus field in the event is to be examined. +If the second argument is not specified, or specified as something other +than \fBalways\fP then if the action is bound to an \fBEnterNotify\fP +or \fBLeaveNotify\fP event, the action will be taken only if the focus +field is \fBTrue\fP. An augmented binding that might be useful is: +.LP +.Ds 0 +.TA 2.0i 2.5i 4.0i +.ta 2.0i 2.5i 4.0i + *Text.Translations: #override \\ + : display-caret(on) \\n\\ + : display-caret(off) +.De +.IP focus-in(\|) 2.0i +.br +.ns +.IP focus-out(\|) 2.0i +These actions do not currently do anything. +.IP search(\fIdirection\fP,[\fIstring\fP]) 2.0i +This action activates the search popup. The \fIdirection\fP must be +specified as either \fBforward\fP or \fBbackward\fP. The string is +optional and is used as an initial value for the \fISearch for\fP: string. +For further explanation of the search widget see the section on +\fBText Searches\fP. +.IP multiply(\fIvalue\fP) 2.0i +The multiply action allows the user to multiply the effects of many of +the text actions. Thus the following action sequence +\fImultiply(10) delete-next-word()\fP will delete 10 words. It does not +matter whether these actions take place in one event or many events. +Using the default translations the key sequence \fIControl-u, +Control-d\fP will delete 4 characters. +Multiply actions can be chained, thus \fImultiply(5) +multiply(5)\fP is the same as \fImultiply(25)\fP. If the string +\fBreset\fP is passed to the multiply action the effects of all previous +multiplies are removed and a beep is sent to the display. +.IP form-paragraph(\|) 2.0i +This action removes all the Carriage Returns from the current +paragraph and reinserts them so that each line is as long as possible, while +still fitting on the current screen. Lines are broken at word boundaries if +at all possible. This action currently works only on Text widgets +that use ASCII text. +.IP transpose-characters(\|) 2.0i +This action will swap the position of the character to the left of the +insert point with the character to the right of the insert point. The insert point will then +be advanced one character. +.IP no-op([\fIaction\fP]) 2.0i +The no-op action makes no change to the text widget, and is mainly used +to override translations. This action takes one optional argument. If +this argument is \fIRingBell\fP then a beep is sent to the display. +.IP XawWMProtocols([\fIwm_protocol_name\fP]) 2.0i +.IN "XawWMProtocols" +.sp +This action is written specifically for the file insertion and the search +and replace +dialog boxes. This action is attached to those shells by the Text widget, +in order to handle ClientMessage events with the WM_PROTOCOLS atom in the +detail field. This action supports WM_DELETE_WINDOW on the Text widget +popups, and may support other window manager protocols if necessary in +the future. The popup will be dismissed if the window manager sends +a WM_DELETE_WINDOW request and there are no parameters in the action +call, which is the default. The popup will also be dismissed if the +parameters include the string ``wm_delete_window,'' and the event is a +ClientMessage event requesting dismissal or is not a ClientMessage event. +This action is not sensitive to the case of the strings passed as parameters. +.IP reconnect-im() 2.0i +.IN "Input Method" +When the \fBinternational\fP resource is \fBtrue\fP, +input is usually passed to an input method, a separate +process, for composing. Sometimes the connection to +this process gets severed; this action will attempt to +reconnect it. Causes for severage include network +trouble, and the user explicitly killing one input +method and starting a new one. This action may also +establish first connection when the application is +started before the input method. +.NH 3 +Text Selections for Application Programmers +.IN "Text widget" "Text Selections for Application Programmers" +.LP +The default behavior of the text selection array is described in the +section called \fBText Selections for Users\fP. To modify the selections +a programmer must construct a \fBXawTextSelectType\fP array (called the +selection array), containing the selections desired, and pass this as +the new value for the \fBselectionTypes\fP resource. The selection +array may also be modified using the \fBXawTextSetSelectionArray\fP +.IN "XawTextSetSelectionArray" "" +function. All selection arrays must end with the value +\fBXawselectNull\fP. The \fBselectionTypes\fP resource has no converter +registered and cannot be modified through the resource manager. +.LP +The array contains a list of entries that will be called when the user +attempts to select text in rapid succession with the \fIselect-start\fP +action (usually by clicking a pointer button). The first entry in the +selection array will be used when the \fIselect-start\fP action is +initially called. The next entry will be used when \fIselect-start\fP +is called again, and so on. If a timeout value (1/10 of a second) is +exceeded, the the next \fIselect-start\fP action will begin at the top +of the selection array. When \fBXawselectNull\fP is reached the array +is recycled beginning with the first element. +.TS +lw(1.25i) lw(4.25i). +T{ +\fBXawselectAll\fP +.IN "XawselectAll" "" +T} T{ +Selects the contents of the entire buffer. +T} +.sp 6p +T{ +\fBXawselectChar\fP +.IN "XawselectChar" "" +T} T{ +Selects text characters as the pointer moves over them. +T} +.sp 6p +T{ +\fBXawselectLine\fP +.IN "XawselectLine" "" +T} T{ +Selects the entire line. +T} +.sp 6p +T{ +\fBXawselectNull\fP +.IN "XawselectNull" "" +T} T{ +Indicates the end of the selection array. +T} +.sp 6p +T{ +\fBXawselectParagraph\fP +.IN "XawselectParagraph" "" +T} T{ +Selects the entire paragraph. +T} +.sp 6p +T{ +\fBXawselectPosition\fP +.IN "XawselectPosition" "" +T} T{ +Selects the current pointer position. +T} +.sp 6p +T{ +\fBXawselectWord\fP +.IN "XawselectWord" "" +T} T{ +Selects whole words as the pointer moves onto them. +T} +.TE +.LP +The default selectType array is: +.LP +.sp +.Ds 0 +{XawselectPosition, XawselectWord, XawselectLine, XawselectParagraph, XawselectAll, XawselectNull} +.De +.sp +.LP +The selection array is not copied by the text widgets.
