OPTIONS

Every mode does not necessarily support every option.

-action: Specifies the type of action to take when clicking on a line in a tablelist -or- a node in a tree. Acceptable values are default (Default), double and single. By default the selected line/node is highlighted. double highlights the line/node for a single click and executes the item command for a double-click. single highlights the line/node and executes the item command for a single-click.
-anchor: Specifies how to place the grid within the master when no row/column has any weight (Default: s).
-attach: Specifies where in a cell that the contents will be "attached". Valid values for this option are n, w and "null" (Default). If the default value (null) is used the contents will be attached to all points - meaning the contents will "stretch" to fill the cell. The other values allow the contents to be attached (justified) to the top and/or left of the cell.
-autogroup: Specifies a string to identify a state group to be set to the "normal" state when the associated entry/text widget is updated. When specified for an entry/widget grid, the group is associated with all entry widgets in the grid.
-background: Specifies the background color.
-basename: Specifies the basename for widget values and commands. Normally the name of a widget value is based on the name of the grid in which it is created. For example: If an entry widget called ".firstname" is created in a grid is called ".person" the value is identified by "$(.person,firstname)". If the basename is set to ".employee" the value will be identified by "$(.empoyee,firstname)". The same principle is also applied to the default names of commands invoked by grid widgets.
-borderwidth: Specifies a non-negative value indicating the width of the 3-D border to draw around the outside of a grid/layout (if such a border is being drawn; the relief option typically determines this).
-calcolor: Specifies the Calendar foreground/background colors.
-calrelief: Specifies the 3-D effect desired for the Calendar border. Acceptable values are raised, sunken, flat (Default), ridge, solid, groove and theme. The value indicates how the interior of the Calendar should appear relative to its exterior; for example, raised means the interior of the Calendar should appear to protrude from the screen, relative to the exterior of the Calendar. When set to theme the Tile theme style is used.
-calselectcolor: Specifies the Calendar foreground/background colors for a selected date.
-ccmd: Specifies command to executed when an associated checkbutton is selected. Alias -checkbuttoncommand.
-century: Specifies a non-negative integer (1-99) to be used as the century window for entry field date validations (Default: 50). Years after the window are considered to be in the previous century. (Example: Assuming -dateformat is us, if the user enters 120160 this will be validated as 12/01/1960).
-cfmt: Specifies, on a per-column basis, the width of the left and right elements. The format is specifed as a list. Each item in the list is applied to the corresponding column in the grid. Each item consists of up to two elements separated by a "/" (left_width/right_width). Each element is optional. Where an element is not specified the width of the column element will be based on the size of the largest widget (as normal). Acceptable formats are: left_width , left_width/right_width, /right_width (Examples: 15 15/25 /25). Alias -columnformat.

-labelstyle: Specifies the label text style (bold or italic) for both labels in a gridplus cell. The style for the left and right labels are separated by a "/". Either may be null, in which case the default label text style is used. The label styles may be a comma delimited list (Example: bold/bold,italic. If the style is to also specify the font size (which must be an integer), the font size must appear first in the list (Example: 12/12,bold).
-linerelief: Specifies the 3-D effect desired for the girdplus line. Acceptable values are raised, sunken (Default), flat, ridge, solid, and groove. The value indicates how the line should appear relative to its exterior; for example, raised means the line should appear to protrude from the screen.

-pad: Specifies a non-negative value indicating how much extra space to request for grids/layouts in both the X and Y directions. When computing how large a window it needs, the widget will add this amount to the height and width it would normally need (as determined by the width and height of the things displayed in the grid/layout); if the geometry manager can satisfy this request, the grid/layout will end up with extra internal space to the left and/or right, top and/or bottom of what it displays inside.

When computing how large a window it needs, the widget will add this amount to the width it would normally need (as determined by the width of the things displayed in the grid/layout); if the geometry manager can satisfy this request, the grid/layout will end up with extra internal space to the left and/or right of what it displays inside.
-pady: Specifies a non-negative value indicating how much extra space to request for grids/layouts in the Y-direction. When computing how large a window it needs, the widget will add this amount to the height it would normally need (as determined by the width of the things displayed in the grid/layout); if the geometry manager can satisfy this request, the grid/layout will end up with extra internal space to the top and/or bottom of what it displays inside.
-pattern: Specifies a regular expression -or- procedure to be associated with a validation. To specify a procedure use the proc:procname format.

-rcmd: Specifies command to executed when an associated radiobutton is selected. Alias -radiobuttoncommand.
-relief: Specifies the 3-D effect desired for the gird/layout border. Acceptable values are raised, sunken, flat (Default), ridge, solid, groove and theme. The value indicates how the interior of the grid/layout should appear relative to its exterior; for example, raised means the interior of the grid/layout should appear to protrude from the screen, relative to the exterior of the grid/layout. When set to theme the Tile theme style is used.

-spacestretch: Specifies, on a per-link basis, whether the link between columns, or column and grid edge, can stretch. The format is specifed as a list. Each item in the list is applied to the corresponding link in the grid. Each element is a boolean value. A value of 0 means the link will not stretch (is "fixed"). 1 means the link will stretch. The default value for format is "null" means that the edge links are fixed and the links between columns stretch. If a single element is specified then all spaces will take that value. Otherwise, the first element is the link between the left edge of the grid and the first column, the last element is the link between the last column and the right edge of the grid. The number of elements in the list must match the number of links in a row. The minimum number of elements is 2 (left and right edges) for a single column row. (Example: {0 0 1 0}, There are three columns. The link between the the first column and the left edge is fixed. The link betwen the first and second columns is fixed. The link between the second and third columns can stretch. The link between the third column and the right edge is fixed.

GRIDPLUS GRID/LAYOUT

In this section "grid" refers to a "GridPlus grid" and "layout" to a "GridPlus layout".

The positions of display items/widgets is defined as a combination of grid layouts and layouts of grids.

The GridPlus grid command, and all of the GridPlus widget grid commands which are built on the GridPlus grid, create a grid of widgets and labels. Any cell in a grid or entry grid may contain a grid, any TK widget or a layout.

The grids are positioned using a layout. The layout is also a grid, but has different options/properties. Any cell within a layout may contain a grid, any TK widget or another layout.

GRID

The grid uses a relative placement facility. Each cell in the grid may have 0,1 or 2 elements. An element begining with "." is considered to be a path to a widget, anything else is considered to be a text label. Each (non-empty) cell may contain a combination of 1 or 2 elements. Normally this would be a widget and a text label, or a widget only, but two widgets or labels is allowed. Each cell consists of two columns. This allows widgets with labels to be easily created and automatically sized/lined-up based on the size of the contents. The order in which the elements appear in the cell is set by the order in which they are defined. The first element into the first column, the second into the second column. If the cell contains a single element this will span both columns. Each element may optionally have a colon (":") delimited sticky indicator, n, s, e, w (Default) or c (Centre). A cell with 0 elements creates an empty cell. A cell may also contain a vertical bar ("pipe"), which will be displayed as a vertical bar separator -or- "=" which will be displayed as a horizontal bar separator.

LAYOUT

The layout command has capabilities similar to that when using the relative placement facility of the Tk grid widget. Each cell may optionally have a delimited sticky indicator, n, s, e, w (Default) or c (Centre). The sticky delimeter may be ":", "=", "|" or "+". Normally the colon (":") delimeter is used. The other options are available to control the grid weight for applications which have resizable windows. Generally "=" should be used for grid cells which are to be resized horizontally, "|" for vertical resizing and "+" for both horizontal and vertical resizing. For text and tree items, where it is required that the item increases/decreases in size as the widow is resized the colon (":") delimeter should be used.
