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.
Class Hierarchy

Types
class WidgetClass o => EntryClass o Source
Instances
castToEntry :: GObjectClass obj => obj -> Entry Source
toEntry :: EntryClass o => o -> Entry Source
Constructors
entryNewWithBuffer :: EntryBufferClass buffer => buffer -> IO Entry Source
Creates a new Entry widget backed by a particular EntryBuffer. One
buffer can be shared among many widgets.
Methods
entrySetText :: (EntryClass self, GlibString string) => self -> string -> IO () Source
Sets the text in the widget to the given value, replacing the current contents.
entryGetText :: (EntryClass self, GlibString string) => self -> IO string Source
Retrieves the contents of the entry widget.
See also editableGetChars.
Arguments
| :: EntryClass self | |
| => self | |
| -> Bool |
|
| -> 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.
Arguments
| :: EntryClass self | |
| => self | |
| -> IO Bool | returns |
Retrieves whether the text in entry is visible. See
entrySetVisibility.
entrySetInvisibleChar :: EntryClass self => self -> Char -> IO () Source
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.
Arguments
| :: EntryClass self | |
| => self | |
| -> IO Char | returns the current invisible char, or |
Retrieves the character displayed in place of the real characters for
entries with visisbility set to false. See entrySetInvisibleChar.
Arguments
| :: EntryClass self | |
| => self | |
| -> Int |
|
| -> 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.
Arguments
| :: EntryClass self | |
| => self | |
| -> IO Int | returns the maximum allowed number of characters in |
Retrieves the maximum allowed length of the text in entry. See
entrySetMaxLength.
entryGetActivatesDefault Source
Arguments
| :: EntryClass self | |
| => self | |
| -> IO Bool | returns |
Query whether pressing return will activate the default widget.
entrySetActivatesDefault Source
Arguments
| :: EntryClass self | |
| => self | |
| -> Bool |
|
| -> 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.
Arguments
| :: EntryClass self | |
| => self | |
| -> IO Bool | returns 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 () Source
Sets whether the entry has a beveled frame around it.
Arguments
| :: EntryClass self | |
| => self | |
| -> IO Int | returns number of chars to request space for, or negative if unset |
Gets the value set by entrySetWidthChars.
Arguments
| :: EntryClass self | |
| => self | |
| -> Int |
|
| -> 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.
Arguments
| :: EntryClass self | |
| => self | |
| -> Float |
|
| -> 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
Arguments
| :: EntryClass self | |
| => self | |
| -> IO Float | returns the alignment |
Gets the value set by entrySetAlignment.
- Available since Gtk version 2.4
entrySetCompletion :: EntryClass self => self -> EntryCompletion -> IO () Source
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
Arguments
| :: EntryClass self | |
| => self | |
| -> IO EntryCompletion | returns The auxiliary completion object currently
in use by |
Returns the auxiliary completion object currently in use by the entry.
- Available since Gtk version 2.4
entryGetBuffer :: EntryClass self => self -> IO EntryBuffer Source
Get the EntryBuffer object which holds the text for this widget.
entrySetBuffer :: (EntryClass self, EntryBufferClass buffer) => self -> buffer -> IO () Source
Set the EntryBuffer object which holds the text for this widget.
entryImContextFilterKeypress :: EntryClass self => self -> EventM EKey Bool Source
Allow the Entry input method to internally handle key press and release events. If this function
returns True, then no further processing should be done for this key event. See
imContextFilterKeypress.
Note that you are expected to call this function from your handler when overriding key event
handling. This is needed in the case when you need to insert your own key handling between the input
method and the default key event handling of the Entry. See textViewResetImContext for
an example of use.
- Available since Gtk+ version 2.22
entryResetImContext :: EntryClass self => self -> IO () Source
Reset the input method context of the entry if needed.
This can be necessary in the case where modifying the buffer would confuse on-going input method behavior.
- Available since Gtk+ version 2.22

Signals
entryActivated :: EntryClass ec => Signal ec (IO ()) Source
A keybinding signal which gets emitted when the user activates the entry.
Applications should not connect to it, but may emit it with signalEmitByName if they need to
control activation programmatically.
entryActivate :: EntryClass ec => Signal ec (IO ()) Source
Deprecated. See entryActivated.
entryBackspace :: EntryClass ec => Signal ec (IO ()) Source
The entryBackspace signal is a keybinding signal which gets emitted when the user asks for it.
The default bindings for this signal are Backspace and Shift-Backspace.
entryCopyClipboard :: EntryClass ec => Signal ec (IO ()) Source
The entryCopyClipboard signal is a keybinding signal which gets emitted to copy the selection to the
clipboard.
The default bindings for this signal are Ctrl-c and Ctrl-Insert.
entryCutClipboard :: EntryClass ec => Signal ec (IO ()) Source
The entryCutClipboard signal is a keybinding signal which gets emitted to cut the selection to the
clipboard.
The default bindings for this signal are Ctrl-x and Shift-Delete.
entryPasteClipboard :: EntryClass ec => Signal ec (IO ()) Source
The entryPasteClipboard signal is a keybinding signal which gets emitted to paste the contents of the
clipboard into the text view.
The default bindings for this signal are Ctrl-v and Shift-Insert.
entryDeleteFromCursor :: EntryClass ec => Signal ec (DeleteType -> Int -> IO ()) Source
The entryDeleteFromCursor signal is a keybinding signal which gets emitted when the user initiates a
text deletion.
If the type is DeleteChars, GTK+ deletes the selection if there is one, otherwise it deletes
the requested number of characters.
The default bindings for this signal are Delete for deleting a character and Ctrl-Delete for deleting a word.
entryInsertAtCursor :: (EntryClass ec, GlibString string) => Signal ec (string -> IO ()) Source
The entryInsertAtCursor signal is a keybinding signal which gets emitted when the user initiates the
insertion of a fixed string at the cursor.
entryMoveCursor :: EntryClass ec => Signal ec (MovementStep -> Int -> Bool -> IO ()) Source
The entryMoveCursor signal is a keybinding signal which gets emitted when the user initiates a cursor
movement. If the cursor is not visible in entry, this signal causes the viewport to be moved
instead.
Applications should not connect to it, but may emit it with signalEmitByName if they need to
control the cursor programmatically.
The default bindings for this signal come in two variants, the variant with the Shift modifier extends the selection, the variant without the Shift modifer does not. There are too many key combinations to list them all here.
- Arrow keys move by individual characters/lines
- Ctrl-arrow key combinations move by words/paragraphs
- Home/End keys move to the ends of the buffer
entryPopulatePopup :: EntryClass ec => Signal ec (Menu -> IO ()) Source
The entryPopulatePopup signal gets emitted before showing the context menu of the entry.
If you need to add items to the context menu, connect to this signal and append your menuitems to the menu.
entryToggleOverwirte :: EntryClass ec => Signal ec (IO ()) Source
The entryToggleOverwrite signal is a keybinding signal which gets emitted to toggle the overwrite mode
of the entry.
The default bindings for this signal is Insert.
entryPreeditChanged :: (EntryClass ec, GlibString string) => Signal ec (string -> IO ()) Source
If an input method is used, the typed text will not immediately be committed to the buffer. So if you are interested in the text, connect to this signal.
entryIconPress :: EntryClass ec => Signal ec (EntryIconPosition -> EventM EButton ()) Source
The iconPress signal is emitted when an activatable icon is clicked.
entryIconRelease :: EntryClass ec => Signal ec (EntryIconPosition -> EventM EButton ()) Source
The iconRelease signal is emitted on the button release from a mouse click over an activatable
icon.
