Width (Property)

In french: Largeur

The Width property gets and changes the width:

of a control or block in a report.
of a control (found in a window), window, column found in a table or column found in a list box (including listview).
of a control (found in a page), column found in a table or column found in a list box. The control can be overlayable or not.

This property also allows you to find out the width of a table cell. To modify its width, modify the width of the corresponding column.

Remarks:

In a report, the border of the control or block is included in its width. The WidthInPixel property is used to get the width in pixels of a control in a report.
The width of a control is defined in the editor in the control description.

Example

// Augmente la largeur du champ "SAI_NomClient"
SAI_NomClient.Largeur = SAI_NomClient.Largeur + 15
// Est équivalent à : SAI_NomClient.Largeur += 15

// Modification de la largeur de deux champs
SAI_NomClient.Largeur += 100	// Ajoute 100 pixels
SAI_PrénomClient.Largeur += 10		// Ajoute 10 pixels

Syntax

Finding out the width of an element Hide the details

<Result> = <Element used>.Width

<Result>: Real

Width of the specified element. This width is expressed in pixels in a window and/or in a page, and in millimeters in a report.

<Element used>: Type of element

Name of the element (control, window, block, ...) to use.

Modifying the width of an element Hide the details

<Element used>.Width = <New width>

<Element used>: Type of element

Name of the element (control, window, block, ...) to use.

<New width>: Real

New width for the specified element. This width is expressed in pixels in a window and/or in a page, and in millimeters in a report.

Remarks

Window width: Special features

The width of a window takes into account the shadow effect defined in the Windows theme.
The width of a window can be different depending on the events in which the Width property is used. This is because the window is resized by the system between the declaration and initialization events, resulting in a potential difference in value:
- in the "Global declarations" event, the window is not yet visible. Therefore, its size has not been set according to the device. The property returns the initial width (edit width) of the window.
- in the "Initialization" event, the window is displayed on the screen, and anchors are applied, as well as size changes. Therefore, the window width can be different.
- The actual width of a window is only known in the initialization event of the window..

Initial width (control and window)

The initial width (defined in the editor) is returned by the InitialWidth property.

In most cases, the width of an element depends on the MaxWidth and MinWidth properties. However, this constraint no longer applies when the width is changed through programming (with the Width property or the WinSize function).

Column width

When the width of a column is changed in a Table control, if the specified width is less than the minimum width, the latter must be modified (using the MinWidth property) to reflect the change.

Horizontal Table control field The property Width PROPERTY property modifies the line height. The Height property is used to get the width of the entire table. This property is read-only.

Width of controls in a form

In server code, the returned and modifiable width corresponds to the total height of the control (width of caption plus width of input area).

In browser code, the returned and modifiable width corresponds to the width of the input area.
