The planes (in a window or in a report)
The planes are used to group the window controls. A plane is a window "layer". Each window can include several planes. The controls can be positioned on different planes. A single plane can be displayed at a time in the window editor and when running the program. Each window control can: - does not belong to any plan: it will always be displayed, regardless of the current plan
- 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 active (i.e. visible).
Remarks: - The planes are also available in the reports. In particular, report layouts can be used to replace substitution blocks: simply place fields on several layouts and activate the required layout when printing.
   The planes can be used on the pages and on the container controls. For more details, see Planes in WEBDEV
Assigning one or more controls to one or more planes To assign one or more controls to one or more planes: - Select the controls.
- Select:
- "Associate .. with a plane" in the context menu of the control or selection of controls in a window.
- "Associate with a plane" in the context menu of the control or selection of controls in a report.
- In the window that is displayed, choose:
- "No plane" if the control must be associated with no plane,
- one of the available planes.
- several planes (to do so, keep the Ctrl key down while selecting planes).
Remarks: - The number of planes is unlimited. However, the window editor or the report 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 control:
- in the window editor: "Detail" tab, "Plan" option.
- in the report editor: "UI" tab, "Plan" option.
- When assigning a field to a plan, the field may no longer appear in the current window or report: the current plan is different from the plan assigned to the field.
- 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: - In the window editor: in the "Window" pane, in the "Associate" group, pull down "Planes".. In the window that opens, simply choose the plane to display in the "Navigation" section.
- In the report editor: in the "Modification" pane, in the "Planes" group, pull down "Planes".. In the window that opens, simply choose the plane to display in the "Navigation" section.
- Press the PgDn and PgUp keys. These keys are used to display the different planes of current window or report.
- Press Ctrl + PgDn and Ctrl + PgUp. These keys are used to display the different planes containing controls (non-empty planes) of the current window or report.
- Type the number of the plane to display in the status bar of window or report editor.
Changing plane programmatically The Plane property allows you to: - find out and change the current plane in a window or report.
- find out and change the plane associated with a control.
Changing plane in a window Changing plane in a window can be performed at any time. A button is often used to change plane. Example: // Switch to plane 4 for adding orders
WIN_CRM.Plane = 4
Plan change is immediate: only fields associated with the plan are displayed. Note: If shots have been named in the window editor, you can use the shot name instead of the shot number. Changing plane in a report The change of plane in a report must be done when printing the report. It is recommended to use the Plane property in one of the events associated with the report, blocks or controls. // Open the report
// Display plane 2
MyReport.Plane = 2
The plan change is immediate: only the fields associated with the plan are printed.. Remark: Replace the substitution blocks with the plans:
Until version 18, the substitution blocks were used to replace a block by another one during the print. However, to avoid the print problems, it was recommend to create substitution blocks with the same height as the block to replace.
From version 19, the planes can easily replace a substitution block. To do so, you must: - in the editor: position substitution block fields in the desired block and assign them to a plan.
- by programming: replace the call to function iSubstBlock with a call to property Plane to display the desired plan.
