DESCRIPTION
The tabnotebook command creates a new window (given by the pathName argument) and makes it into a tabnotebook widget. Additional options, described above may be specified on the command line or in the option database to configure aspects of the tabnotebook such as its colors, font, and text. The tabnotebook command returns its pathName argument. At the time this command is invoked, there must not exist a window named pathName, but pathName's parent must exist.
A tabnotebook is a widget that contains a set of tabbed pages. It displays one page from the set as the selected page. A Tab displays the label for the page to which it is attached and serves as a page selector. When a page's tab is selected, the page's contents are displayed in the page area. The selected tab has a three-dimensional effect to make it appear to float above the other tabs. The tabs are displayed as a group along either the left, top, right, or bottom edge. When first created a tabnotebook has no pages. Pages may be added or deleted using widget commands described below.
A special option may be provided to the tabnotebook. The -auto option specifies whether the tabnotebook will automatically handle the unpacking and packing of pages when pages are selected. A value of true signifies that the notebook will automatically manage it. This is the default value. A value of false signifies the notebook will not perform automatic switching of pages.
NOTEBOOK PAGES
A tabnotebook's pages area contains a single child site frame. When a new page is created it is a child of this frame. The page's child site frame serves as a geometry container for applications to pack widgets into. It is this frame that is automatically unpacked or packed when the auto option is true. This creates the effect of one page being visible at a time. When a new page is selected, the previously selected page's child site frame is automatically unpacked from the tabnotebook's child site frame and the newly selected page's child site is packed into the tabnotebook's child site frame.However, sometimes it is desirable to handle page changes in a different manner. By specifying the auto option as false, child site packing can be disabled and done differently. For example, all widgets might be packed into the first page's child site frame. Then when a new page is selected, the application can reconfigure the widgets and give the appearance that the page was flipped.
In both cases the command option for a page specifies a Tcl Command to execute when the page is selected. In the case of auto being true, it is between the unpacking of the previously selected page and the packing of the newly selected page.
Notebook pages can also be controlled with scroll bars or other widgets that obey the scrollcommand protocol. By giving a scrollbar a -command to call the tabnotebook's select method, the tabnotebook can be controlled with a scrollbar.
The notebook area is implemented with the notebook mega widget.
TABS
Tabs appear along the edge of the notebook area. Tabs are drawn to appear attached to their associated page. When a tab is clicked on, the associated page is selected and the tab is drawn as raised above all other tabs and as a seamless part of its notebook page. Tabs can be controlled in their location along the edges, the angle tab sides are drawn with, gap between tabs, starting margin of tabs, internal padding around text labels in a tab, the font, and its label.The Tab area is implemented with the tabset mega widget. See tabset(1). Tabs may be oriented along either the north, south, east, or west sides with the tabPos option. North and south tabs may appear as angled, square, or bevelled. West and east tabs may appear as square or bevelled. By changing tab gaps, tab angles, bevelling, orientations, colors, fonts, start locations, and margins; tabs may appear in a wide variety of styles. For example, it is possible to implement Microsoft-style tabs, Borland property tab styles, or Borland Delphi style tabs all with the same tabnotebook.
WIDGET-SPECIFIC METHODS
The tabnotebook command creates a new Tcl command whose name is pathName. This command may be used to invoke various operations on the widget. It has the following general form:
pathName option ?arg arg ...?option and the args determine the exact behavior of the command.
Many of the widget commands for a notebook take as one argument an indicator of which page of the notebook to operate on. These indicators are called indexes and may be specified in any of the following forms:
- number
- Specifies the page numerically, where 0 corresponds to the first page in the notebook, 1 to the second, and so on.
- select
- Specifies the currently selected page's index. If no page is currently selected, the value -1 is returned.
- end
- Specifes the last page in the tabnotebook's index. If the notebook is empty this will return -1.
- pattern
- If the index doesn't satisfy any of the above forms, then this form is used. Pattern is pattern-matched against the label of each page in the notebook, in order from the first to the last page, until a matching entry is found. The rules of Tcl_StringMatch are used. '............................................................................. The following commands are possible for tabnotebook widgets:
- pathName add ?option value option value ...?
- Add a new page at the end of the tabnotebook. A new child site frame is created. Returns the child site pathName. If additional arguments are present, they specify any of the following options:
- -angle value
- Specifes the angle of slope from the inner edge to the outer edge of the tab. An angle of 0 specifies square tabs. Valid ranges are 0 to 45 degrees inclusive. Default is 15 degrees. If this option is specified as an empty string (the default), then the angle option for the overall tabnotebook is used. This is generally only set at the tabnotebook level. Tabs normally will want to share the same angle value.
- -background value
- Specifies a background color to use for displaying tabs when they are selected and for displaying the current page. If this option is specified as an empty string (the default), then the background option for the overall tabnotebook is used.
- -bevelamount value
- Specifes the size of tab corners. A value of 0 with angle set to 0 results in square tabs. A bevelAmount of 4, means that the tab will be drawn with angled corners that cut in 4 pixels from the edge of the tab. The default is 0. This is generally only set at the tabnotebook level. Tabs normally will want to share the same bevelAmount.
- -bitmap value
- If label is a non-empty string, specifies a bitmap to display in this page's tab. Bitmap may be of any of the forms accepted by Tk_GetPixmap.
- -command value
- Specifies a Tcl command to be executed when this page is
selected. This allows the programmer a hook to reconfigure this
page's widgets or any other page's widgets.
If the tabnotebook has the auto option set to true, when a page is selected this command will be called immediately after the previously selected page is unpacked and immediately before this page is selected. The index value select is valid during this Tcl command. `index select' will return this page's page number.If the auto option is set to false, when a page is selected the unpack and pack calls are bypassed. This Tcl command is still called.
- -disabledforeground value
- Specifies a foreground color to use for displaying tab labels when tabs are in their disable state. If this option is specified as an empty string (the default), then the disabledforeground option for the overall tabnotebook is used.
- -font value
- Specifies the font to use when drawing a text label on a page tab. If this option is specified as an empty string then the font option for the overall tabnotebook is used..
- -foreground value
- Specifies a foreground color to use for displaying tab labels when they are selected. If this option is specified as an empty string (the default), then the foreground option for the overall tabnotebook is used.
- -label value
- Specifies a string to display as an identifying label for a notebook page. This label serves as an additional identifier used to reference the page. This label may be used for the index value in widget commands.
- -tabbackground value
- Specifies a background color to use for displaying a tab when it is not elected. If this option is specified as an empty string (the default), then the tabBackground option for the overall tabnotebook is used.
- -tabforeground value
- Specifies a foreground color to use for displaying the tab's text label when it is not selected. If this option is specified as an empty string (the default), then the tabForeground option for the overall tabnotebook is used.
- -padx value
- Specifies a non-negative value indicating how much extra space to request for a tab around its label in the X-direction. When computing how large a window it needs, the tab will add this amount to the width it would normally need The tab will end up with extra internal space to the left and right of its text label. This value may have any of the forms acceptable to Tk_GetPixels. If this option is specified as an empty string (the default), then the padX option for the overall tabnotebook is used
- -pady value
- Specifies a non-negative value indicating how much extra space to request for a tab around its label in the Y-direction. When computing how large a window it needs, the tab will add this amount to the height it would normally need The tab will end up with extra internal space to the top and bottom of its text label. This value may have any of the forms acceptable to Tk_GetPixels. If this option is specified as an empty string (the default), then the padY option for the overall tabnotebook is used
- -state value
- Specifies one of two states for the page: normal or disabled. In normal state unselected tabs are displayed using the tabforeground and tabbackground option from the tabnotebook or the page. Selected tabs and pages are displayed using the foreground and background option from the tabnotebook or the page. The disabled state means that the page and its tab is insensitive: it doesn't respond to mouse button presses or releases. In this state the entry is displayed according to its disabledForeground option for the tabnotebook and the background/tabbackground option from the page or the tabnotebook.
- '>>>>>>>>>>
- pathName childSite ?index? If passed no
arguments, returns a list of pathNames for all the pages in the
tabnotebook. If the tab notebook is empty, an empty list is
returned
If index is passed, it returns the pathName for the page's child site frame specified by index. Widgets that are created with this pathName will be displayed when the associated page is selected. If index is not a valid index, an empty string is returned.
- pathName configure ?option? ?value option value ...?
- Query or modify the configuration options of the widget. If no option is specified, returns a list describing all of the available options for pathName (see Tk_ConfigureInfo for information on the format of this list). If option is specified with no value, 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 option is specified). If one or more option-value 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. Option may have any of the values accepted by the tabnotebook command.
- pathName delete index1 ?index2?
- Delete all of the pages between index1 and index2 inclusive. If index2 is omitted then it defaults to index1. Returns an empty string.
- pathName index index
- Returns the numerical index corresponding to index.
- pathName insert index ?option value option value ...?
- Insert a new page in the tabnotebook before the page specified by index. A new child site frame is created. The additional arguments are the same as for the add command. Returns the child site pathName.
- pathName next
- Advances the selected page to the next page (order is
determined by insertion order). If the currently selected page is
the last page in the notebook, the selection wraps around to the
first page in the notebook. It behaves as if the user selected the
new page.
For notebooks with auto set to true the current page's child site is unpacked from the notebook's child site frame. Then the next page's child site is packed into the notebook's child site frame. The Tcl command given with the command option will be invoked between these two operations.For notebooks with auto set to false the Tcl command given with the command option will be invoked.
- pathName pageconfigure index ?option? ?value option value ...?
- This command is similar to the configure command, except that it applies to the options for an individual page, whereas configure applies to the options for the tabnotebook as a whole. Options may have any of the values accepted by the add widget command. If options are specified, options are modified as indicated in the command and the command returns an empty string. If no options are specified, returns a list describing the current options for page index (see Tk_ConfigureInfo for information on the format of this list).
- pathName prev
- Moves the selected page to the previous page (order is
determined by insertion order). If the currently selected page is
the first page in the notebook, the selection wraps around to the
last page in the notebook. It behaves as if the user selected the
new page.
For notebooks with auto set to true the current page's child site is unpacked from the notebook's child site frame. Then the previous page's child site is packed into the notebook's child site frame. The Tcl command given with the command option will be invoked between these two operations.For notebooks with auto set to false the Tcl command given with the command option will be invoked.
- pathName select index
- Selects the page specified by index as the currently
selected page. It behaves as if the user selected the new page.
For notebooks with auto set to true the current page's child site is unpacked from the notebook's child site frame. Then the index page's child site is packed into the notebook's child site frame. The Tcl command given with the command option will be invoked between these two operations.For notebooks with auto set to false the Tcl command given with the command option will be invoked.
- pathName view
- Returns the currently selected page. This command is for compatibility with the scrollbar widget.
- pathName view index
- Selects the page specified by index as the currently selected page. This command is for compatibility with the scrollbar widget.
- pathName view moveto fraction
- Uses the fraction value to determine the corresponding page to move to. This command is for compatibility with the scrollbar widget.
- pathName view scroll num what
- Uses the num value to determine how many pages to move forward or backward (num can be negative or positive). The what argument is ignored. This command is for compatibility with the scrollbar widget.
COMPONENTS
Generally all behavior of the internal components, tabset and notebook are controlled via the pageconfigure method. The following section documents these two components.
