Introduction

The "AbvLayout" program is used to define the screen resolution as well as the screen splitting between Header=, Alarm=, Application= and Menu area.
With the definitions set up here the editor is used to create the process pictures displayed in the runtime.
So the settings done here must mainly take care of what will be expected in runtime. At least the width-to-height ratio should be the same in the editing and the runtime environment.

The set up once made must not be changed for the same project.

• There must be an Application area
• The size of any area may be defined freely
• The position of an area may be defined freely
• An area may be defined only once

The ‘AbvLayout’ is called via the icon .

A similar program window is opened:



Im geöffneten LAYOUT wird eine standard Bildaufteilung mit den möglichen Bereichen dargestellt.

Picture Area

4 picture areas are possible:

• Header area
• Alarm area
• Application area
• Menu area

Any area may exist once, the arrangement of areas is free selectable.

This area is optional, in runtime a picture of the type "Header area" is displayed here. Typically the header is located at the upper border of the screen and keeps general information like program name, logo, date, time and the like.

This area is optional, in runtime a picture of the type "Alarm area" is displayed here. Typically the latest alarm is displayed here.

This area is compulsive, in runtime pictures of the type "Application area", the process pictures, are displayed here.

This area is optional, in runtime a picture of the type "Menu area" is displayed here. Typically that controls the picture selection or the like.

The area to modify is selected by mouse click, a selection frame is shown. The ‘handles’ may be used to resize the area, by pressing the mouse button the whole area can be moved.

The status line below can be used to size and position any area to the pixel.

The status line shows the selected area or informs about the next step of a selected action.

The further fields inform about:

• 'x' - 'y' - Are the coordinates of the left upper corner of the selected area.
• 'dx' and 'dy' - Telling the size of the selected area.
• Very left – The count of the selected areas.

Pull-down menu ‘File’

With target resolution the screen resolution is set.

A dialog window is opened:

Pull-down menu ‘Insert’

Possible areas are listed here; only areas not defined yet are selectable and may be inserted.

The mouse pointer becomes a cross-hair, the X, Y fields in the status line show the coordinates of the cross-hair, dX, dY are empty, the field on the very right shows the count of already existing areas.
On the wanted position press the left mouse button to setup the wanted size.
The status line shows the X, Y position of the upper left corner of the area – dX, dY the size of the inserted area. The count in the very right status field is incremented by one.

Pull-down menu ‘Arrange’

On overlapping areas only the part in the foreground is visible.
That menu item is only for support on setting up the areas, on the final setting the areas must not overlap at all.

A submenu becomes active – (at least 2 areas must be marked).
It allows aligning marked areas:

• Top: The top edges of all selected areas are aligned to the most top edge of the selected areas; the size of any area is kept.
• Bottom: The bottom edges of all selected areas are aligned to the most bottom edge of the selected areas; the size of any area is kept.
• VCenter: All selected areas are vertical centered; the size of any area is kept.
• Left: The left edges of all selected areas are aligned to the most left edge of the selected areas; the size of any area is kept.
• Right: The right edges of all selected areas are aligned to the most right edge of the selected areas; the size of any area is kept.
• HCenter: All selected areas are horizontal centered; the size of any area is kept.

A submenu becomes active.
It allows to mirror the marked areas on a horizontal / vertical axis.

Mit Drehen wird ein Untermenü aktiviert.
It allows rotating the marked areas in steps of 90° counter clockwise.

Pull-down menu ‘Setup’

If ‘Snap to Grid’ is activated (box is checked), it is only possible to select positions on the grid when editing.

The grid is displayed.

A dialog to set the grid distance is opened.

A dialog to set the following parameters is opened.

Window frame	Width of the window frame in pixel.
Caption height	Height of the title in pixel.
System area height	Height of the system line in pixel.

“Ok” stores the setup, “Cancel” closes the window without storing.
