Bars Style Dialog


This dialog allows you to create, edit and/or delete the bars styles used to represent task parameters in Gantt charts.

The available Gantt bars are listed under the Elements heading. Selecting what bars should be drawn is done by checking the checkboxes next to the bar name.

Creating a new bar

To add new box, select an existing box and click on the [Plus] button. The selected item will be copied and a new entry in the list will be created. The new entry will be uniquely named, but its name will start with the name of the task copied. If there is no selected item, then the new item is initialized with the default box.

The listbox on the right contains the flags that determine if and when the box should be displayed.

  1. Example:

    Uncheck all items in the left list. Check the Summary item. Uncheck all flags that are in the list on the right. Check the Summary flag. The definition will apply to the summaries, which are the only tasks that will be drawn.

  2. Example:

    Do the same as above, but this time use Critical instead of summary. Only the critical tasks will be displayed.

Note: Care should be exercised as a task may satisfy more than combination of flags, in which case all applicable definitions will be used and the result may be unseemly.

Each flag can be unchecked in which case it is ignored. It can be marked with a [+] or [-], indicating that the condition to draw the task may be the positive or negative. The actual condition is the conjunction of all positive and all negative flags.

Selecting a bar will cause the Edit tab to become visible. Selecting the Edit tab will show the bar's color and shape attributes, decorations and other visual attributes of the bar

Deleting a bar

To delete a bar select its name and press [-].

Note: The last bar remaining cannot be deleted.

Editing the Bar's Appearence

The following items can be used to specify the Gantt bar appearence:

  • Left, Middle and Right. each of which has the following attributes:
    • Shape - Shape of gantt bar (see Item shapes).

      Note: Not all shapes are suitable for Gantt bars. Some shapes (like regular polygons and polygrams) are suitable suitable only for the Left and Right part.

    • Border - (see Line description)
    • Interior - (see Brush description)
    • Visble flag - set if the task is to be displayed

    For example, if we examine a simple task bar, we will notice that the shapes for First and Last parts are set to None. If on the other hand we examine a normal summary gantt bar, we shall see that the First and Last parts have identical shapes defined. In addition to those one can specify additional symbols to denote a deadline, say.

  • Row - number of row within the task rendering space.

    Tracking gantt, for example, makes use only of the first row (#1). There is nothing to prevent using Rows #1 and #2 for the to display the actual and baseline Gantt bars, but using just the first row is more Microsoft-like.

  • Labels that appear around the bar, e.g. resource names, completion percentage, etc. The lables can be place on the left, at the center or on the right of gantt bar and be aligned on the top, middle or bottom of the bar.

Note: There is no limit on the number of rows that can be specified. Large number of rows may slow rendering down and make any practical display of tasks uninformative. MS Project limits the number of rows to 4.
