Correction orthographique

4D inclut des fonctionnalités de correction orthographique intégrées et personnalisables. Text type inputs can be checked, as well as 4D Write Pro documents.

The Auto Spellcheck property activates the spell-check for each object. When used, a spell-check is automatically performed during data entry. You can also execute the SPELL CHECKING 4D language command for each object to be checked.

Context Menu

Allows the user access to a standard context menu in the object when the form is executed.

For a picture type input, in addition to standard editing commands (Cut, Copy, Paste and Clear), the menu contains the Import... command, which can be used to import a picture stored in a file, as well as the Save as... command, which can be used to save the picture to disk. The menu can also be used to modify the display format of the picture: the Truncated non-centered, Scaled to fit and Scaled to fit centered prop. options are provided. The modification of the display format using this menu is temporary; it is not saved with the record.

For a multi-style text type input, in addition to standard editing commands, the context menu provides the following commands:

  • Fonts...: displays the font system dialog box
  • Recent fonts: displays the names of recent fonts selected during the session. The list can store up to 10 fonts (beyond that, the last font used replaces the oldest). By default, this list is empty and the option is not displayed. You can manage this list using the SET RECENT FONTS and FONT LIST commands.
  • commands for supported style modifications: font, size, style, color and background color. When the user modifies a style attribute via this pop-up menu, 4D generates the On After Edit form event.

For a Web Area, the contents of the menu depend of the rendering engine of the platform. It is possible to control access to the context menu via the WA SET PREFERENCE command.

Saisissable

The Enterable attribute indicates whether users can enter values into the object.

Objects are enterable by default. If you want to make a field or an object non-enterable for that form, you can disable the Enterable property for the object. A non-enterable object only displays data. You control the data by methods that use the field or variable name. You can still use the On Clicked, On Double Clicked, On Drag Over, On Drop, On Getting Focus and On Losing Focus form events with non-enterable objects. This makes it easier to manage custom context menus and lets you design interfaces where you can drag-and-drop and select non-enterable variables.

When this property is disabled, any pop-up menus associated with a list box column via a list are disabled.

Filtres de saisie

Un filtre de saisie contrôle exactement ce que l’utilisateur peut taper au clavier pendant la saisie. Unlike required lists for example, entry filters operate on a character-by-character basis. Par exemple, si un numéro de composant est toujours constitué de trois lettres suivies de trois chiffres, vous pouvez contraindre la saisie à respecter cette forme. You can even control the particular letters and numbers.

Un filtre de saisie n’est effectif que pendant la saisie. Il n’a aucun effet sur l’affichage des données une fois que l'objet est désélectionné. In general, you use entry filters and display formats together. Le filtre agit pendant la saisie et le format d’affichage assure un affichage approprié de la valeur après sa saisie.

Pendant la saisie de données, un filtre de saisie évalue chaque caractère au moment où il est saisi. Si l’utilisateur tente de taper un caractère invalide (un chiffre à la place d’une lettre, par exemple), 4D refuse la saisie du caractère. The null character remains unchanged until the user types a valid character.

Les filtres de saisie peuvent aussi être utilisés pour afficher des caractères de formatage afin d’éviter à l’utilisateur de les taper. Par exemple, un numéro de téléphone français est constitué d’un chiffre de code opérateur suivi d’un chiffre de zone et d’un nombre à huit chiffres groupés par paires. Un format d’affichage peut être utilisé pour afficher le code opérateur entre parenthèses et pour afficher un tiret entre les paires de chiffres. Lorsqu’un tel format est utilisé, l’utilisateur n’a pas besoin de saisir les parenthèses ou le tiret.

Définition d'un filtre de saisie

Most of the time, you can use one of the built-in filters of 4D for what you need; however, you can also create and use custom filters:

  • you can directly enter a filter definition string
  • or you can enter the name of an entry filter created in the Filters editor in the Toolbox. The names of custom filters you create begin with a vertical bar (|).

For information about creating entry filters, see Filter and format codes.

    Focusable

    When the Focusable property is enabled for an object, the object can have the focus (and can thus be activated by the keyboard for instance). It is outlined by a gray dotted line when it is selected — except when the Hide focus rectangle option has also been selected.

    An input object is always focusable if it has the Enterable property.


    • Check box shows focus when selected


    • Check box is selected but cannot show focus|

    When the Focusable property is selected for a non-enterable object, the user can select, copy or even drag-and-drop the contents of the area.

    Keyboard Layout

    This property associates a specific keyboard layout to an input object. For example, in an international application, if a form contains a field whose contents must be entered in Greek characters, you can associate the "Greek" keyboard layout with this field. This way, during data entry, the keyboard configuration is automatically changed when this field has the focus.

    By default, the object uses the current keyboard layout.

    You can also set and get the keyboard dynamically using the OBJECT SET KEYBOARD LAYOUT and OBJECT Get keyboard layout commands.

    Multilignes

    This property is available for inputs objects containing expressions of the Text type and fields of the Alpha and Text type. Elle peut prendre trois valeurs : Oui, Non, Automatique (par défaut).

    Automatique

    • Dans les zones mono-lignes, les mots situés en fin de ligne sont tronqués et il n’y a pas de retours à la ligne.
    • In multiline inputs, 4D carries out automatic line returns:\

    Non

    • Dans les zones mono-lignes, les mots situés en fin de ligne sont tronqués et il n’y a pas de retours à la ligne.
    • Il n’y a aucun retour à la ligne : le texte est toujours affiché sur une seule ligne. If the Alpha or Text field or variable contains carriage returns, the text located after the first carriage return is removed as soon as the area is modified:\

    Oui

    When this value is selected, the property is managed by the Wordwrap option.

    Le placeholder

    4D can display placeholder text in the fields of your forms.

    Placeholder text appears as watermark text in a field, supplying a help tip, indication or example for the data to be entered. This text disappears as soon as the user enters a character in the area:

    The placeholder text is displayed again if the contents of the field is erased.

    A placeholder can be displayed for the following types of data:

    • string (text or alpha)
    • date and time when the Blank if null property is enabled.

    You can use an XLIFF reference in the ":xliff:resname" form as a placeholder, for example:

    :xliff:PH_Lastname

    You only pass the reference in the "Placeholder" field; it is not possible to combine a reference with static text.

    You can also set and get the placeholder text by programming using the OBJECT SET PLACEHOLDER and OBJECT Get placeholder commands.

    Raccourci

    This property allows setting special meaning keys (keyboard shortcuts) for buttons, radio buttons, and checkboxes. They allow the user to use the control using the keyboard instead of having to use the mouse.

    You can configure this option by clicking the [...] button in the Shortcuts property in the Property List.

    You can also assign a shortcut to a custom menu command. If there is a conflict between two shortcuts, the active object has priority. For more information about associating shortcuts with menus, refer to Setting menu properties.

    Saisie sur clic unique

    Enables direct passage to edit mode in list boxes.

    When this option is enabled, list box cells switch to edit mode after a single user click, regardless of whether or not this area of the list box was selected beforehand. Note that this option allows cells to be edited even when the list box selection mode is set to "None".

    When this option is not enabled, users must first select the cell row and then click on a cell in order to edit its contents.
