Graphic items

The graphic item is an object that can be created in the panel editor. It is the basic construction element of the PROMOTIC system application panel (of the PmPanel object). By means of graphic items it is possible to create an application panel that serves for the visualization of data, their inputs, controlling, etc.

The graphic item can be inserted into the panel from the "Graphic items preconfigurations" window.

Basic terms:
Window item: This item creates its own sub-window (this window has the same dimensions as the graphic item itself) when drawing the panel whose parent is the window where the whole panel is drawn. That's why the window items always overlap all common items on the desktop independently on the background in which they were constructed. Limitation when creating compound items: items cannot be nested into window items.

A list of the window items: PmiAx, PmiWEdit, PmiWCheck, PmiWCombo, PmiWFrame and PmiWAnimate.

Marked item: This item is bound by a set of points (2 to 8 according to the item type) in the shape of small squares. There can be more marked items together. The marked item can be at the same time even the current item. How to mark items - see: Basic control of panel editor.
Current item: It is an item on which the mouse cursor was placed in a moment of pressing the left or right mouse button. The name of this item is written to the the status line on each change of the mouse cursor. The current item can be the marked item at the same time.
