Detail
The Entry widget is a single line text entry widget. A fairly large set of key bindings are supported by default. If the entered text is longer than the allocation of the widget, the widget will scroll so that the cursor position is visible.

Constructors
entryNew :: IO Entry
Creates a new Entry widget.
Methods
entrySetText :: EntryClass self => self -> String -> IO ()
Sets the text in the widget to the given value, replacing the current contents.
entryGetText :: EntryClass self => self -> IO String
Retrieves the contents of the entry widget. See also editableGetChars.
entryAppendText :: EntryClass self => self -> String -> IO ()

Appends the given text to the contents of the widget.

  • Warning: this function is deprecated and should not be used in newly-written code.
entryPrependText :: EntryClass self => self -> String -> IO ()

Prepends the given text to the contents of the widget.

  • Warning: this function is deprecated and should not be used in newly-written code.
entrySetVisibility
:: EntryClass self
=> self
-> Boolvisible - True if the contents of the entry are displayed as plaintext.
-> IO ()

Sets whether the contents of the entry are visible or not. When visibility is set to False, characters are displayed as the invisible char, and will also appear that way when the text in the entry widget is copied elsewhere.

The default invisible char is the asterisk '*', but it can be changed with entrySetInvisibleChar.

entryGetVisibility
:: EntryClass self
=> self
-> IO Boolreturns True if the text is currently visible
Retrieves whether the text in entry is visible. See entrySetVisibility.
entrySetInvisibleChar :: EntryClass self => self -> Char -> IO ()
Sets the character to use in place of the actual text when entrySetVisibility has been called to set text visibility to False. i.e. this is the character used in "password mode" to show the user how many characters have been typed. The default invisible char is an asterisk ('*'). If you set the invisible char to '\0', then the user will get no feedback at all; there will be no text on the screen as they type.
entryGetInvisibleChar
:: EntryClass self
=> self
-> IO Charreturns the current invisible char, or '\0', if the entry does not show invisible text at all.
Retrieves the character displayed in place of the real characters for entries with visisbility set to false. See entrySetInvisibleChar.
entrySetMaxLength
:: EntryClass self
=> self
-> Intmax - the maximum length of the entry, or 0 for no maximum. (other than the maximum length of entries.) The value passed in will be clamped to the range 0-65536.
-> IO ()
Sets the maximum allowed length of the contents of the widget. If the current contents are longer than the given length, then they will be truncated to fit.
entryGetMaxLength
:: EntryClass self
=> self
-> IO Intreturns the maximum allowed number of characters in Entry, or 0 if there is no maximum.
Retrieves the maximum allowed length of the text in entry. See entrySetMaxLength.
entryGetActivatesDefault
:: EntryClass self
=> self
-> IO Boolreturns True if the entry will activate the default widget
Query whether pressing return will activate the default widget.
entrySetActivatesDefault
:: EntryClass self
=> self
-> Boolsetting - True to activate window's default widget on Enter keypress
-> IO ()

If setting is True, pressing Enter in the entry will activate the default widget for the window containing the entry. This usually means that the dialog box containing the entry will be closed, since the default widget is usually one of the dialog buttons.

(For experts: if setting is True, the entry calls windowActivateDefault on the window containing the entry, in the default handler for the "activate" signal.)

This setting is useful in Dialog boxes where enter should press the default button.

entryGetHasFrame
:: EntryClass self
=> self
-> IO Boolreturns whether the entry has a beveled frame
Query if the text Entry is displayed with a frame around it.
entrySetHasFrame :: EntryClass self => self -> Bool -> IO ()
Sets whether the entry has a beveled frame around it.
entryGetWidthChars
:: EntryClass self
=> self
-> IO Intreturns number of chars to request space for, or negative if unset
Gets the value set by entrySetWidthChars.
entrySetWidthChars
:: EntryClass self
=> self
-> IntnChars - width in chars
-> IO ()

Changes the size request of the entry to be about the right size for nChars characters. Note that it changes the size request, the size can still be affected by how you pack the widget into containers. If nChars is -1, the size reverts to the default entry size.

This setting is only considered when the widget formulates its size request. Make sure that it is not mapped (shown) before you change this value.

entrySetAlignment
:: EntryClass self
=> self
-> Floatxalign - The horizontal alignment, from 0 (left) to 1 (right). Reversed for RTL layouts
-> IO ()

Sets the alignment for the contents of the entry. This controls the horizontal positioning of the contents when the displayed text is shorter than the width of the entry.

  • Available since Gtk version 2.4
entryGetAlignment
:: EntryClass self
=> self
-> IO Floatreturns the alignment

Gets the value set by entrySetAlignment.

  • Available since Gtk version 2.4
entrySetCompletion :: EntryClass self => self -> EntryCompletion -> IO ()

Sets the auxiliary completion object to use with the entry. All further configuration of the completion mechanism is done on completion using the EntryCompletion API.

  • Available since Gtk version 2.4
entryGetCompletion
:: EntryClass self
=> self
-> IO EntryCompletionreturns The auxiliary completion object currently in use by entry.

Returns the auxiliary completion object currently in use by the entry.

  • Available since Gtk version 2.4
