Each property editor contains dialogue controls for parameters to provide a convenient way of changing the values for each object type within a MapFile. The property editors of the map or the currently selected layer are displayed at the bottom of the Layer Panel. The property editor can also be displayed by right clicking an object in the Layer Panel and selecting the Properties menu item.
In most cases changing a property won't be reflected immediately in the map view. You can edit multiple properties and press the OK or the Apply button to accept the changes and redraw the map accordingly. You can also revert the changes by clicking on the Cancel button.
When selecting a new item in the layer panel without accepting the pending changes MapManager displays the following warning message.
You can choose to accept or ignore the pending changes by pressing the Yes or No button respectively.
