16.6 Methods on text widgetsTo create a text widget as the child of a root window or frame named master:w = Text ( master, *options )The constructor returns the new text widget. Options include:backgroundThe default background color of the text widget.May be abbreviated as bg.borderwidthThe width of the border around the text widget.Default is 2 pixels.cursorThe cursor that will appear when the mouse is overthe text widget. See Cursors, above.exportselection Normally, text selected within a text widget is exportedto be the selection in the window manager.Set this option to 0 if you don’t want that behavior.fontThe default font for text inserted into the widget.Note that you can have multiple fonts in the widgetsby using tags to change the properties of sometext. See Fonts, above.foregroundThe color used for text (and bitmaps) within thewidget. You can change the color for tagged regions;this option is just the default. May be abbreviatedas fg.heightThe height of the widget in lines (not pixels!), measuredaccording to the current font size.highlightbackground The color of the focus highlight when the text widgetdoes not have focus. See Focus, below.highlightcolor The color of the focus highlight when the text widgethas the focus. See Focus, below.highlightthickness The thickness of the focus highlight. Default is 1.Set to 0 to suppress display of the focus highlight.See Focus, below.insertbackground The color of the insertion cursor. Default is black.insertborderwidth Size of the 3-D border around the insertion cursor.Default is 0.insertofftime The number of milliseconds the insertion cursor isoff during its blink cycle. Set this option to zero tosuppress blinking. Default is 300.insertontime The number of milliseconds the insertion cursor ison during its blink cycle. Default is 600.insertwidthWidth of the insertion cursor (its height is determinedby the tallest in its line). Default is 2 pixels.padxThe size of the internal padding added to the leftand right of the text area. Default is one pixel.padyThe size of the internal padding added above andbelow the text area. Default is one pixel.reliefThe 3-D appearance of the text widget. Default isSUNKEN.selectbackground The background color to use displaying selectedtext.selectborderwidth The width of the border to use around selected text.New Mexico Tech Computer Center Tkinter reference: The Text widget Page 52
selectforegroundspacing1spacing2spacing3statetabstakefocuswidthThe foreground color to use displaying selectedtext.This option specifies how much extra vertical spaceis put above each line of text. If a line wraps, thisspace is added only before the first line it occupieson the display. Default is 0.This option specifies how much extra vertical spaceto add between displayed lines of text when a logicalline wraps. Default is 0.This option specifies how much extra vertical spaceis added below each line of text. If a line wraps, thisspace is added only after the last line it occupies onthe display. Default is 0.Normally, text widgets respond to keyboard andmouse events; set this option to NORMAL to get thisbehavior. If you set state to DISABLED, the textwidget will not respond, but you won’t be able tomodify its contents programmatically either.This option controls how tab characters positiontext. The default is to place tabs every eight characters.To set specific tab stops, set this option to asequence of one or more distances.For example, setting tabs to ("3c", "5c", "12c")would put tab stops 3, 5, and 12cm from the leftside. Tabs past the last one you set have the samewidth as the distance between the last two existingtab stops.Normally, text after a tab character is aligned withits left edge on the tab stop, but you can include anyof the keywords LEFT, RIGHT, CENTER, or NUMERICin the list after a distance, and that will change thepositioning of the text after each tab.A LEFT tab stop has the default behavior. A RIGHTtab stop will position the text so its right edge is onthe stop, and a CENTER tab will center the followingtext on the tab stop. A NUMERIC tab stop will placefollowing text to the left of the stop up until the firstperiod (.) in the text—after that, the period will becentered on the stop, and the rest of the text willpositioned to its right.For example, setting tabs to the sequence("0.5i", "0.8i", RIGHT, "1.2i", CENTER,"2i", NUMERIC) would set four tab stops: a leftalignedtab stop half an inch from the left side,a right-aligned tab stop 0.8 ′′ from the left side, acenter-aligned tab stop 1.2 ′′ from the left, and anumeric-aligned tab stop 2 ′′ from the left.Normally, focus will visit a text widget (see Focus,below). Set takefocus to 0 if you do not wantfocus in the widget.The width of the widget in characters (not pixels!),measured according to the current font size.New Mexico Tech Computer Center Tkinter reference: The Text widget Page 53
