DESCRIPTION

The Entry widget extends the default Tk entry. Options have been added to provide visual effect depending on the state of the Entry, DynamicHelp options, and Drag and Drop. Entry behaves much like a Label, with text option to set its contents.
Tk entry command can also be used on Entry widget.

WIDGET-SPECIFIC OPTIONS

-command
  Specifies a command when user press <Return> in the Entry.

-dragenabled
  A boolean specifying if drag is enabled.

-dragendcmd
  Specifies a command to be called when drag ended. dragendcmd must be a command conforming to the description of the option dragendcmd of DragSite::register.
  If dragendcmd is empty, the internal dragend command updates the entry following the operation (move or copy) and the dragged data (whole or selected part of the entry).

-dragevent
  Specifies the number of the mouse button associated to the drag. Must be 1, 2 or 3.

-draginitcmd
  Specifies a command to be called when dragevent occurs on widget. draginitcmd must be a command conforming to the description of the option draginitcmd of DragSite::register.
  if draginitcmd is empty, the command refuse the drag if entry is empty or if portion of text is selected and event doesn't occur above the selection. In all other cases, the command returns:
  - as the data type, the value of option dragtype or TEXT if empty,
  - as the operations, {copy move} if state is normal and editable is true, or {copy} only in other cases,
  - as the data, the whole content or the selected portion of the entry.

-dragtype
  Specifies an alternate type of dragged object.

-dropcmd
  Entry has a command wrapper for drop events. This command stops auto scrolling and extract current position.
  If dropcmd is not empty, it is called with the following arguments:
  - the pathname of the Entry,
  - the pathname of the drag source,
  - the numeric index in the entry designated by the cursor,
  - the current operation,
  - the data type,
  - the data.
  and must return a value conforming to dropcmd option described in DropSite::register. If dropcmd is empty, the wrapper updates the entry following the type of data:

    COLOR or FGCOLOR | reconfigure the foreground of the Entry
    BGCOLOR | reconfigure the background of the Entry
    TEXT, or any other tag | reconfigure the Entry to display the associated string.

  and returns 1.

-dropenabled
  A boolean specifying if drop is enabled.

-dropovercmd
  Entry has a command wrapper for drag-over events. This command enables auto scrolling and position extraction during the drag-over.
  If dropovercmd is empty, the wrapper accepts the drop if editable option is true and state option is normal.
  If dropovercmd is not empty, it is called with the following arguments:
  - the pathname of the Entry,
  - the pathname of the drag source,
  - the event,
  - the numeric index in the entry designated by the cursor,
  - the current operation,
  - the data type,
  - the data.
  and must return a value conforming to dropovercmd option described in DropSite::register.

-droptypes
  Specifies a list of accepted dropped object/operation. See option droptypes of DropSite::register. for more infromation. Default accepts FGCOLOR, COLOR, BGCOLOR and TEXT, all with copy and move operations.

-editable
  Specifies whether the Entry is editable by the user. Equivalent to the state option of the Tk entry widget.

-helptext
  Text for dynamic help. If empty, no help is available for this widget. See also DynamicHelp.

-helptype
  Type of dynamic help. Use balloon or variable. See also DynamicHelp.

-helpvar
  Variable to use when helptype option is variable. See also DynamicHelp.

-show
  If this option is specified, then the true contents of the entry are not displayed in the window. Instead, each character in the entry's value will be displayed as the first character in the value of this option, such as ``*''. This is useful, for example, if the entry is to be used to enter a password. If characters in the entry are selected and copied elsewhere, the information copied will be what is displayed, not the true contents of the entry.

-state
  Specifies one of two states for the Entry: normal or disabled. In normal state the text of the Entry is displayed using the foreground option. In disabled state the text of the Entry is displayed using the disabledforeground option. If the entry is disabled then the value may not be changed by user input and no insertion cursor will be displayed, even if the input focus is in the widget. Disabled state is the same as not editable with visual effect.

-width
  Specifies an integer value indicating the desired width of the entry window, in average-size characters of the widget's font. If the value is less than or equal to zero, the widget picks a size just large enough to hold its current text.

WIDGET COMMAND

pathName cget option
  Returns the current value of the configuration option given by option. Option may have any of the values accepted by the creation command.

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. 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 creation command. Read-only options are not be modified.

pathName invoke
  Calls the command specified by the option -command.
