Input

Inputs allow you to add enterable or non-enterable expressions such as database fields and variables to your forms. Inputs can handle character-based data (text, dates, numbers...) or pictures:

Inputs can contain assignable or non-assignable expressions.

In addition, inputs can be enterable or non-enterable. An enterable input accepts data. You can set data entry controls for the object. A non-enterable input can only display values but cannot be edited by the user.

You can manage the data with object or form methods.

note

For security reasons, in multi-style input areas, when formulas are pasted from a different 4D application or an external environment, only the computed values (text or images) available at the time of copying are pasted. If no value was available (e.g., the formula was never computed), 4D pastes the formula source as plain text.

JSON Example:

	"myText": {
		"type": "input",	//define the type of object
		"spellcheck": true,	//enable spelling verification
		"left": 60,			//left position on the form  
		"top": 160,			//top position on the form 
		"width": 100,		//width of the object
		"height": 20		//height of the object
		}

Input alternatives

You can also represent field and variable expressions in your forms using alternative objects, more particularly:

• You can display and enter data from database fields directly in columns of selection type List boxes.
• You can represent a list field or variable directly in a form using Pop-up Menus/Drop-down Lists and Combo Boxes objects.
• You can represent a boolean expression as a check box or as a radio button object.
