This is achieved by changing the level of the object. A level of 0 indicates the object is at the bottom of the pile, whereas a level equal to the number of objects (less one) indicates the object is on the top of the pile. To place an object behind another object, the level of that object must be taken down below the level of the object it is to be placed behind. To place an object in front of another object, the level of that object must be taken up above the level of the object it is to be placed in front of. If you only have three objects in the draw window, then 0 is at the bottom, 1 is in the middle and 2 is at the top. Moving an object forward from level 0 to level 1, changes the level of the object that was originally at level 1 to level 0, and the object that was originally at level 0 to level 1. This keeps the relationship intact with 0 at the bottom, 1 in the middle and 2 on top (the bottom object has now moved in front of the middle object).To change an objects level, activate the objects menu and select the level option, The level dialog will appear. Simply increment the level using the spinner or type the level number in directly and press return.
As a short cut, it is possible to move the object right to the back or right to the front by pressing the front or back buttons.
When a group is ungrouped, all the objects within the group are inserted between the objects that were immediately in front of and bind the group.
