- Properties specific to MapCircle variables
- WLanguage functions
MapCircle (Variable type) In french: CarteCercle
The MapCircle type is used to define the characteristics of a circle to be drawn on the map displayed in a Map control. You can define and change the characteristics of this circle using different WLanguage properties. Note: For more details on the declaration of this type of variable and the use of WLanguage properties, see Declaring a variable.
Circle is MapCircle
Circle.Center = Position
Circle.Radius = 50
Circle.LineColor = LightRed
Circle.ActionClick = ClickProc
MapAddShape(MAP_MyMap, Circle)
INTERNAL PROCEDURE ClickProc(c is MapCircle)
ToastDisplay(StringBuild("Click on the <%1> circle.", c.Name))
END
Properties Properties specific to MapCircle variables The following properties can be used to handle a circle: | | | Property name | Type used | Effect |
---|
ActionClick | Procedure name | Name of the WLanguage procedure called when the user clicks the circle displayed in the Map control. This procedure has the following format:
PROCEDURE <Procedure name>(<Circle>) where <Circle> is a MapCircle variable corresponding to the circle that the user clicked on. If this property is not specified (or corresponds to an empty string ("")), no action will be performed on click. Note: it is advisable to use global procedures. If the procedure is a local procedure, it is necessary to prefix the procedure name with the full name of the object to which the procedure belongs (e.g. for a local window procedure: "FEN_Fenêtre1.MaProcedure"). | BackgroundColor | Color, integer, Integer constant | Circle background color. This color can correspond to:Note: To change the fill opacity, write: MyMapCircle.BackgroundColor.Opacity = 50
| Center | geoPosition | Center of the circle. | Description | Character string | Description of the shape, used to store additional information, for example. | New in version 2025Extra | Variant | Allows you to store advanced information without affecting the execution of the application. You can store values of any type (array, etc.). It is also possible to add members to the Extra property. Example:
MyVariable.Extra.Info1 = Value MyVariable.Extra[Info2] = Value2 MyVariable.Extra.Date = DateSys() | Line | Integer constant | Line style used for the circle outline: - ContinuousTrait (default): Solid line.
 - Dotted line: Dotted line.
 - TraitTiret: Dashes.
 - MixedTrait: Dotted and dashed lines.

| LineColor | Color, integer, Integer constant | Circle outline color. This color can correspond to: | Name | Character string | Name of the shape (here, name of the circle). A name is automatically assigned when the variable is created. It can be modified, but it has to be unique if the shape is added to the Map control. This name can be used to delete the circle with MapDeleteShape. | Radius | Real | Radius of the circle in meters. The default radius is 100 meters. | Thickness | Integer | Line thickness used for the circle outline. The thickness is set to 2 by default. | ZOrder | Integer | Z-order of the circle in relation to the other shapes in the Map control. Allows you to manage overlays. A shape with a high Z-order will be drawn over a shape with a lower Z-order. This property is set to 0 by default. |
Remarks WLanguage functions The following WLanguage functions use MapCircle variables:
| | MapAddShape | Adds a new shape (polygon, line, circle) to the map displayed in a Map control. | MapDeleteShape | Deletes a shape drawn on the map displayed in an Map control. | MapModifyShape | Modifies a shape drawn on the map displayed in a Map control. |
