Caption (Property)

In french: Libellé

In a database, the Caption property is used to:

Find out the caption associated with a file item.
Remark: The item was created in the data model editor or through programming.
Find out the caption associated with a data file.
Remark: The data file may have been created in the data model editor or through programming.
Find out and modify the connection caption. The connection can correspond to:
- a connection described in the data model editor,
- a connection described by HConnect, HDescribeConnection or HOpenConnection.
- a connection described by a Connection variable.

In a report, the Caption property is used to get and change the text:

of a Static control.
of a Link control.
Versions 17 and later
of a Chart control.
New in version 17
of a Chart control.
of a Chart control.

In a window or page, the Caption property is also used to:

Find out and modify the caption of a control in a window or in a page.
Find out and modify the caption of a menu option.
Find out and modify the title of a window or page.

Reminder: The initial caption of a control, window, page or menu option is defined in the editor during the object description.

Example

// Find out the caption associated with the Customer.Title item
ResCaption = Customer.Title.Caption

// Modify the text in the "STC_IntroControl" Static control
STC_IntroControl.Caption = "Hello" + Customer.FullName
// Equivalent to: STC_IntroControl.Caption = "Hello [%Customer.FullName%]"

Syntax

Finding out the text of caption associated with an element Hide the details

<Result> = <Element used>.Caption

<Result>: Character string

Text displayed in the specified element.

<Element used>: Type of element

Name of the element to be used.

Modifying the text of caption associated with an element Hide the details

<Element used>.Caption = <New text>

<Element used>: Type of element

Remarks

Content of Static control

To retrieve the value of a control or the value of an item in a Static control:

In the report editor: insert [%<Control name>%] or [%<Item name>%] directly into the caption of the control.
In programming: there are two possible syntaxes with the Caption property:
- use directly the [%<Control name>%] or [%<Item name>%] string in the string that corresponds to the caption. For example:
  
  STC_IntroControl.Caption = "Hello [%Customer.FullName%]"
- use the name of the control or the name of the item in the caption. For example:
  
  STC_IntroControl.Caption = "Hello" + Customer.FullName

Equivalence

The Caption and Value properties are equivalent.

To retrieve the text of a Static control, the following syntaxes are equivalent:

ResCaption = <Static control>.Caption

ResCaption = <Static control>.Value

ResCaption = <Static control>

To modify the text displayed in a Static control, the following syntaxes are equivalent:

<Name of Static control>.Caption = <New text>

<Name of Static control>.Value = <New text>

<Name of Static control> = <New text>

Caption associated with an Image control

The Caption property returns or replaces the current image with the image passed as parameter.

The Caption property has the same effect as assigning the name of the image to the control (Control = Image_Name).

The Image control includes a caption: the Caption property is used to change this text. If the new caption does not correspond to a valid image, the caption of the Image control is modified.

Caption associated with a button

The Caption property can have two actions:

replace the image of the button (the name passed as parameter corresponds to an image file),
return or replace the button caption (the text passed as parameter is not an image file name).

For example:

// Modify the image of a graphic button
BTN_Button1.Caption = "Help.BMP"

// Modify the caption of a text button
BTN_Button1.Caption = "New caption"

Remark: If the specified text contains the & character, the letter that follows & is interpreted as the shortcut of the control.

Limitations

In a report, the Caption property can only be used on "Static" and "Link" controls.
