Following properties can be set via Properties Dialog.

Visibility

You may show or hide objects in the Graphics View in different ways.

  • You may use tool Tool Show Hide Object.gif Show/Hide Object Tool to show or hide objects.
  • Open the Context Menu and select item Tool Show Hide Object.gif Show Object to change the visibility status of the selected object.
  • In the Algebra View, the icon to the left of every object shows its current visibility state (shown shown or hidden hidden). You may directly click on the little marble icon in order to change the visibility status of an object.
  • You can also use the Tool Check Box to Show Hide Objects.gif Check Box to Show/Hide Objects Tool in order to show or hide one or several objects.
Note: To make an object "invisible" in Algebra View, make it Auxiliary.

Fixed objects

You can define an object to be fixed via Properties Dialog. Fixed objects (both free and dependent) cannot be moved, redefined or deleted.

Filling

For for closed Curves and regions you can specify filling using the Style tab of Object properies dialog. Theree are three types of filling:

Standard
Fills the object by color specified in the color tab. The same color is used to draw border of that object. Using Style tab you can define opacity -- e.g. Conics have by default opacity 0 which means they are transparent.
Hatch
The object is hatched, angle of hatches and distance between them can be specified. Thickness of hatches equals the thickness of object's border.
Image
You can specify location of image on the local disc. The image is repeated periodically, its size is fixed in pixels and top left corner is aligned to the top left corner of the view.
