Such +text widgets are known as peer text widgets. +.PP +As text is added, deleted, edited and coloured in any one widget, and as +images, marks, tags are adjusted, all such changes will be reflected in +all peers. +.PP +All data and markup is shared, except for a few small details. First, +the \fBsel\fR tag may be set and configured (in its display style) +differently for each peer.

+all aspects of the widget's appearance are controlled by the style of +the widget (i.e. the style of the elements of the widget). +.SH "THEMES" +.PP +A \fItheme\fR is a collection of elements and styles +that determine the look and feel of the widget set. +Themes can be used to: +.IP \(bu +isolate platform differences (X11 vs. classic Windows vs. XP vs. Aqua ...) +.IP \(bu +adapt to display limitations (low-color, grayscale, monochrome, tiny screens) +.IP \(bu +accessibility (high contrast, large type) +.IP \(bu +application suite branding +.IP \(bu +blend in with the rest of the desktop (Gnome, KDE, Java) +.IP \(bu +and, of course: eye candy. +.SH "ELEMENTS" +.PP +An \fIelement\fR displays an individual part of a widget. +For example, a vertical scrollbar widget contains \fBuparrow\fR, +\fBdownarrow\fR, \fBtrough\fR and \fBslider\fR elements. +.PP +Element names use a recursive dotted notation. +For example, \fBuparrow\fR identifies a generic arrow element, +and \fBScrollbar.uparrow\fR and \fBCombobox.uparrow\fR identify +widget-specific elements. +When looking for an element, the style engine looks for +the specific name first, and if an element of that name is +not found it looks for generic elements by stripping off +successive leading components of the element name. +.PP +Like widgets, elements have \fIoptions\fR which +specify what to display and how to display it. +For example, the \fBtext\fR element +(which displays a text string) has +\fB\-text\fR, \fB\-font\fR, \fB\-foreground\fR, \fB\-background\fR, +\fB\-underline\fR, and \fB\-width\fR options. +The value of an element option is taken from: +.IP \(bu +an option of the same name and type in the widget containing the element; +.IP \(bu +a dynamic setting specified by \fBstyle map\fR and the current state; +.IP \(bu +the default setting specified by \fBstyle configure\fR; or +.IP \(bu +the element's built-in default value for the option. +.SH "LAYOUTS" +.PP +A \fIlayout\fR specifies which elements make up a widget +and how they are arranged. +The layout engine uses a simplified version of the \fBpack\fR +algorithm: starting with an initial cavity equal to the size +of the widget, elements are allocated a parcel within the cavity along +the side specified by the \fB\-side\fR option, +and placed within the parcel according to the \fB\-sticky\fR +option. +For example, the layout for a horizontal scrollbar is: +.PP +.CS +ttk::\fBstyle layout\fR Horizontal.TScrollbar { + Scrollbar.trough \-children { + Scrollbar.leftarrow \-side left \-sticky w + Scrollbar.rightarrow \-side right \-sticky e + Scrollbar.thumb \-side left \-expand true \-sticky ew + } +} +.CE +.PP +By default, the layout for a widget is the same as its class name. +Some widgets may override this (for example, the \fBttk::scrollbar\fR +widget chooses different layouts based on the \fB\-orient\fR option). +.SH "STATES" +.PP +In standard Tk, many widgets have a \fB\-state\fR option +which (in most cases) is either \fBnormal\fR or \fBdisabled\fR. +Some widgets support additional states, such +as the \fBentry\fR widget which has a \fBreadonly\fR state +and the various flavors of buttons which have \fBactive\fR state. +.PP +The themed Tk widgets generalizes this idea: +every widget has a bitmap of independent state flags. +Widget state flags include \fBactive\fR, \fBdisabled\fR, +\fBpressed\fR, \fBfocus\fR, etc., +(see \fIttk::widget(n)\fR for the full list of state flags). +.PP +Instead of a \fB\-state\fR option, every widget now has +a \fBstate\fR widget command which is used to set or query +the state. +A \fIstate specification\fR is a list of symbolic state names +indicating which bits are set, each optionally prefixed with an +exclamation point indicating that the bit is cleared instead. +.PP +For example, the class bindings for the \fBttk::button\fR +widget are: +.PP +.CS +bind TButton <Enter> { %W state active } +bind TButton <Leave> { %W state !active } +bind TButton <ButtonPress-1> { %W state pressed } +bind TButton <Button1-Leave> { %W state !pressed } +bind TButton <Button1-Enter> { %W state pressed } +bind TButton <ButtonRelease-1> \e + { %W instate {pressed} { %W state !pressed ; %W invoke } } +.CE +.PP +This specifies that the widget becomes \fBactive\fR when +the pointer enters the widget, and inactive when it leaves. +Similarly it becomes \fBpressed\fR when the mouse button is pressed, +and \fB!pressed\fR on the ButtonRelease event. +In addition, the button unpresses if +pointer is dragged outside the widget while Button-1 is held down, +and represses if it's dragged back in. +Finally, when the mouse button is released, the widget's +\fB\-command\fR is invoked, but only if the button is currently +in the \fBpressed\fR state. +(The actual bindings are a little more complicated than the above, +but not by much). +'\" Note to self: rewrite that paragraph. It's horrible. +.SH "STYLES" +.PP +Each widget is associated with a \fIstyle\fR, +which specifies values for element options. +Style names use a recursive dotted notation like layouts and elements; +by default, widgets use the class name to look up a style in the current theme. +For example: +.PP +.CS +ttk::\fBstyle configure\fR TButton \e + \-background #d9d9d9 \e + \-foreground black \e + \-relief raised \e + ; +.CE +.PP +Many elements are displayed differently depending on the widget state. +For example, buttons have a different background when they are active, +a different foreground when disabled, and a different relief when pressed. +The \fBstyle map\fR command specifies dynamic option settings +for a particular style: +.PP +.CS +ttk::\fBstyle map\fR TButton \e + \-background [list disabled #d9d9d9 active #ececec] \e + \-foreground [list disabled #a3a3a3] \e + \-relief [list {pressed !disabled} sunken] \e + ; +.CE +.SH "SEE ALSO" +ttk::widget(n), ttk::style(n) +'\" Local Variables: +'\" mode: nroff +'\" End: diff --git a/doc/ttk_label.n b/doc/ttk_label.n new file mode 100644 index 0000000..3987585 --- /dev/null +++ b/doc/ttk_label.n @@ -0,0 +1,80 @@ +'\" +'\" Copyright (c) 2004 Joe English +'\" +'\" See the file "license.terms" for information on usage and redistribution +'\" of this file, and for a DISCLAIMER OF ALL WARRANTIES. +'\" +'\" RCS: @(#) $Id: ttk_label.n,v 1.9.2.2 2010/08/26 02:06:09 hobbs Exp $ +'\" +.so man.macros +.TH ttk::label n 8.5 Tk "Tk Themed Widget" +.BS +.SH NAME +ttk::label \- Display a text string and/or image +.SH SYNOPSIS +\fBttk::label\fR \fIpathName \fR?\fIoptions\fR? +.BE +.SH DESCRIPTION +.PP +A \fBttk::label\fR widget displays a textual label and/or image. +The label may be linked to a Tcl variable +to automatically change the displayed text. +.SO ttk_widget +\-class \-compound \-cursor +\-image \-style \-takefocus +\-text \-textvariable \-underline +\-width +.SE +.SH "WIDGET-SPECIFIC OPTIONS" +.OP \-anchor anchor Anchor +Specifies how the information in the widget is positioned +relative to the inner margins.
