WIDGET-SPECIFIC OPTIONS

[-editdonecmd editDoneCmd] If non-empty, gives a Tcl command to be executed when the user has edited grid cell. When this command is called, it is passed with two additional parameters: x y, where (x,y) is the location of the cell that has just been edited. [-editnotifycmd editNotifyCmd] If non-empty, gives a Tcl command to be executed when the user tries to edit a grid cell. When this command is called, it is passed with two additional parameters: x y, where (x,y,) is the location of the cell. This command should return a boolean value: true indicates that the cells is editable and false otherwise. [-formatcmd formatCmd] If non-empty, gives a Tcl command to be executed when the grid cells need to be formatted on the screen. Normally, this command calls the format widget command (see below). When this command is called, it is passed with five additional parameters: type x1 y1 x2 y2. type gives the logical type of the region in the grid. It may be one of the following. x-region: the horizontal margin; y-region: the vertical margin; s-region, the area where the the horizontal and vertical margins are joined; main: all the cells that do not fall into the above three types. x1 y1 x2 y2 gives the extent of the region that needs formatting. [-leftmargin leftMargin] In the number of cells, gives the width of vertical margin. A zero indicates that no vertical should be drawn. [-selectmode selectMode] Specifies one of several styles for manipulating the selection. The value of the option may be arbitrary, but the default bindings expect it to be either single, browse, multiple, or extended; the default value is single. [-selectunit selectUnit] Specifies the selection unit. Valid values are cell, column or row. [-topmargin topMargin] In the number of cells, gives the height of horizontal margin. A zero indicates that no horizontal should be drawn.

DESCRIPTION

The tixGrid command creates a new window (given by the pathName argument) and makes it into a tixGrid widget. Additional options, described above, may be specified on the command line or in the option database to configure aspects of the tixGrid widget such as its cursor and relief.

A Grid widget displays its contents in a two dimensional grid of cells. Each cell may contain one Tix display item, which may be in text, graphics or other formats. See the tixDisplayStyle manual page for more information about Tix display items. Individual cells, or groups of cells, can be formatted with a wide range of attributes, such as its color, relief and border.

WIDGET COMMAND

The tixGrid command creates a new Tcl command whose name is the same as the path name of the tixGrid widget's window. This command may be used to invoke various operations on the widget. It has the following general form:

pathName option ?arg arg ...?
PathName is the name of the command, which is the same as the tixGrid widget's path name. Option and the args determine the exact behavior of the command. The following commands are possible for tixGrid widgets:
Manipulates the anchor cell of the tixGrid widget. The anchor cell is the end of the selection that is fixed while the user is dragging out a selection with the mouse.
TODO place holder
Returns the current value of the configuration option given by option. Option may have any of the values accepted by the tixGrid command.
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(n) 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 tixGrid command.
Dim may be row or column. If to is not given, deletes a single row (or column) at the position from. If to is given, deletes the range of rows (or columns) from position from through to.
If any cell is being edited, de-highlight the cell and applies the changes.
Highlights the cell at (x,y) for editing, if the -editnotify command returns true for this cell.
Returns the current value of the configuration option given by option of the cell at (x,y). Option may have any of the values accepted by the set widget command.
Query or modify the configuration options of the cell at (x,y). If no option is specified, returns a list describing all of the available options for the cell (see Tk_ConfigureInfo(n) 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 set widget command.

Dim may be row or column. Moves the the range of rows (or columns) from position from through to by the distance indicated by offset. For example, move row 2 4 1 moves the rows 2,3,4 to rows 3,4,5.
Creates a new display item at the cell at (x,y). The optional -itemtype parameter gives the type of the display item. An additional list of option-value pairs specify options of the display item. If a display item already exists at this cell, the old item will be deleted automatically.
Queries or sets the size of the row or column given by dim and index. Dim may be row or column. Index may be any non-negative integer that gives the position of a given row (or column). Index can also be the string default; in this case, this command queries or sets the default size of all rows (or columns).

When no option-value pair is given, this command returns a list containing the current size setting of the given row (or column). When option-value pairs are given, the corresponding options of the size setting of the given row are changed. Option may be one of the follwing:

Specifies the paddings to the left or a column or the top of a row.
Specifies the paddings to the right or a column or the bottom of a row.
Specifies the width of a column or the height of a row. Val may be: auto -- the width of the column is set the the widest cell in the column; a valid Tk screen distance unit (see Tk_GetPixels(n)); or a real number following by the word chars (e.g. 3.4chars) that sets the width of the column to the given number of characters.
Clears the cell at (x,y) by removing its display item.
