GtkDataEntry implements AtkImplementorIface, GtkBuildable, GtkEditable and GtkCellEditable.
GtkDataEntry provides additional properties:
“description” - no functionality, a place for private information that cannot be put anywhere else
“datatype” - no functionality, a datatype hint for the application because any widget content is text
“dataformat” - a formatting instruction that controls what you see when the widget doesn't have input focus
“text” - set the contents of the widget. if the widget doesn't have input focus text will be formatted according to the data_format
“max-length-bytes” - set the maximum byte length for the contents of the widget.
The main reason for this widget is to provide a formatting entry widget for numeric data like integer, float, money which also supports NULL values (GtkSpinButton is nice but doesn't support empty field values). Handling of Null values is supported by all SQL database systems. The Null values are represented by empty field contents.
When editing field contents, all data formatting is removed before the focus enters the widget. As soon as the focus leaves the widget, data will be nicely formatted again.
As an additional feature, the minus sign (negative numbers) can be entered at the end of the data. As soon as you leave the field it will be placed properly in front of the number.

const gchar *
gtk_data_entry_get_description (GtkDataEntry *data_entry);
Retrieves the GtkDataEntry description.
void gtk_data_entry_set_description (GtkDataEntry *data_entry,const gchar *description);
Sets the GtkDataEntry description.
Basically, you can use the description for your own programming purpose. The GtkDataEntry recognizes the keywords below, which have a special meaning.
Ignore(vString) - silently ignore all characters in vString
Map(vString1|vString) - map each character in vString1 to the corresponding character in vString2 with the same index
Accept(vString) - accept only characters in vString, sound bell for invalid characters
Reject(vString) - ignore all characters in vString, sound bell for invalid characters
Evaluation order: Ignore, Map, not Accept or Reject
vString's are a literate character lists. They may contain valid utf-8 character sequences and the following escape sequences: \a, \b, \f, \n, \r, \t, \v, \. vStrings are not quoted like a normal C string, they are delimited by round brackets or the pipe symbol, see above.
const gchar *
gtk_data_entry_get_data_type (GtkDataEntry *data_entry);
Retrieves the GtkDataEntry data_type.
void gtk_data_entry_set_data_type (GtkDataEntry *data_entry,const gchar *data_type);
Sets the GtkDataEntry data type for application use.
const gchar *
gtk_data_entry_get_data_format (GtkDataEntry *data_entry);
Retrieves the GtkDataEntry data_format.
See gtk_data_format() for details.
void gtk_data_entry_set_data_format (GtkDataEntry *data_entry,const gchar *data_format);
Sets the GtkDataEntry data type for application use. The display will not be refreshed upon change.
See gtk_data_format() for details.
const gchar *
gtk_data_entry_get_text (GtkDataEntry *data_entry);
Retrieves the GtkDataEntry contents. All formatting will be removed.
void gtk_data_entry_set_text (GtkDataEntry *data_entry,const gchar *text);
Sets the GtkDataEntry contents. The contents will be formatted due to the current data_format.
gint
gtk_data_entry_get_max_length_bytes (GtkDataEntry *data_entry);
Retrieves the maximum byte length for the contents of GtkDataEntry.
Since: 3.0.6
void gtk_data_entry_set_max_length_bytes (GtkDataEntry *data_entry,gint max_length_bytes);
Sets the maximum byte length for the contents of the GtkDataEntry. Existing content will not be truncted.
Since: 3.0.6
“dataformat” property“dataformat” gchar *
a formatting string that controls what you see when the widget doesn't contain input focus.
See gtk_data_format() for details.
Flags: Read / Write
Default value: ""
“datatype” property“datatype” gchar *
no functionality, a datatype hint for the application because any widget content is text.
Flags: Read / Write
Default value: ""
“description” property“description” gchar *
Description of the GtkDataEntry, no functionality, a place for private information that cannot be put anywhere else.
Flags: Read / Write
Default value: ""
“max-length-bytes” property“max-length-bytes” gint
Set the maximum length in bytes for the GtkDataEntry. For details see gtk_data_entry_set_max_length_bytes.
Sometimes, systems cannot handle UTF-8 string length correctly, to overcome this problem, you can use the maximum string length in bytes. When setting both limits, max-length and max-length-bytes, both must be fulfilled.
Flags: Read / Write
Allowed values: [0,65535]
Default value: 0
Since: 3.0.6
“text” property“text” gchar *
Set the contents of the GtkDataEntry. For details see gtk_data_entry_set_text.
Flags: Read / Write
Default value: ""
