The planes are used to group the element controls. A plane is a "layer" of an element. Each element can be made of several planes.
WEBDEV proposes the management of planes for the following elements:
- the pages,
- the internal pages,
- the cells,
- the layout areas,
- the popups,
- the supercontrols,
- the control templates,
- the page templates.
The controls can be positioned on different planes. A single plane can be displayed at a time in the page editor and when running the site.
Each element control can:
- belong to a plane. This control will be displayed when the corresponding plane is enabled (which means visible).
- belong to several planes. This control will be displayed when one of the planes associated with the control is enabled (which means visible).
Implementation: Enabling the management of planes
How to proceed?
To use the planes in WEBDEV, the management of planes must be enabled for the requested element:
- Display the element description window.
- In the "UI" tab, check "Enable management of planes".
- Validate the description window of the element.
- The planes are available for the element. If the display of planes is allowed in the editor, the digit 1 used to identify the first plane appears at the top right of element.
Remark: To manage the display of the plane number in the editor, in the "Display" pane, in the "View (all controls)" group, check "Planes".
When the management of planes is enabled, you have the ability to create the requested controls and to associate them with the different planes.
Delayed plane load
When enabling planes, you can check "Delayed loading of plane content".
This option is used to load data from planes faster. Indeed, if the planes contain a lot of data to display, the page may take quite long to load. You can improve this by loading the data only when the relevant plane is displayed: this is called "delayed loading".
If "Delayed loading of plane content" is checked when planes are enabled, two new events are associated with the element:
- Delayed loading of a plane (Server) in AJAX.
- Delayed loading of a plane (Browser).
In these events, you can use ..Plane
to identify the active plane. This makes it possible to carry out only the processing to initialize the fields of the plan concerned.
// Code for delayed load (server) of CELL_VARIOUS
CASE 1 // Displaying the list of customers
CASE 2 // Displaying the orders of selected customer
CustomerID is int = TABLE_Customer.Col_CustomerNum
CASE 3 // Order details
OrdNum is int = TABLE_Order.Col_OrderNum
- Looper control: You have the ability to use planes for each repetition. All you have to do is create a cell for each repetition. This cell contains the planes to display. A "Plane" attribute is used to manage the number of the plane displayed.
- Table control: You have the ability to use planes in a container column, by using a cell for example.
- If the planes are managed at page level, the zoning is defined for each plane.
- Several planes can be used in each layout area.
- Scrolling Banner control: The Scrolling Banner control is using the planes to display the different banner elements. In this case, the management of planes is specific. See The Sliding Banner control for more details.
Assigning one or more controls to one or more planes
Case 1: Creating controls:
When creating a control on an element containing planes, the created control is automatically associated with the visible plane.
Case 2: Associating existing controls with one or more planes:
To assign one or more controls to one or more planes:
- Select the controls.
- "Associate with a plane" from the popup menu of selection.
- "Associate with a plane" from the popup menu of control.
- In the window that is displayed, choose:
- one of the available planes.
- several planes (to do so, keep the Ctrl key down while selecting planes).
- A control positioned on an element containing planes is always associated with a plane.
There is no plane 0, used to make a control visible regardless of the plane displayed. To manage this case, all you have to do is define different areas, for example an area containing no plane and an area containing planes.
- If a control is associated with several planes, it automatically become stackable.
- The number of planes is unlimited. However, the page editor may prevent you from selecting the planes greater than 98.
- A control can also be assigned to a plane from the description window of the control ("UI" tab, "Plane" option).
- When assigning a control to a plane, the plane to which the control is assigned is automatically displayed in the editor.
- The assignments window lists the planes used then the blank planes. The buttons found at the bottom of this window simplify the move between the different types of planes.
Selecting the plane displayed in the editor
To display a specific plane in the editor, you can:
- Select (if necessary) the element for which the planes must be displayed.
- Press the PgDn and PgUp keys. These keys are used to display the different planes of the current element (or the different planes of the parent control of the selection).
If the display of planes is allowed in the editor, the number of the current plane is displayed at the top right of element.
Changing plane by programming
property is used to:
- find out and change the current plane of an element.
- find out the plane associated with a control.
Changing plane in an element
Changing plane in an element can be performed at any time. A Button control is often used to change planes.
// Switch to plane 4 for adding orders
PAGE_CRM.CELL_OrdCell..Plane = 4
The change of plane is immediate: only the controls associated with the plane are displayed.
Effects when changing plane
The change of plane can be done with effects. you have the ability to define effects:
- for the element that manages the planes. In the "Style" tab, you must:
- select the "Effects" element.
- click "Add an effect".
- select an effect for changing planes and configure it via the "Details" button. You have the ability to specify how the effect will be triggered (change of plane, go to previous plane, ...)
- for the elements found in the plane, by managing specific effects for the appearance or disappearance of controls. In the "Style" tab, you must:
- select the "Effects" element.
- click "Add an effect".
- select an appearance or disappearance effect and configure it via the "Details" button: several animations are then proposed.
Caution: The effects operate only if the page is not re-displayed. In order for the effect to be visible, ..Plane
must be called in browser code or in Ajax server code.
