Gradient List Control Overview
The Fractal Science Kit fractal generator Gradient List Control is found on Classic Controllers, Orbit Trap Controllers, and Orbital Controllers. It maintains an ordered list of Gradients available to the controller. The controller can access the gradients in this list using the Gradient Functions. Typically, the controller includes a GradientIndex Option in the properties section of the program instructions to allow the user to choose one of the gradients to use.
The Gradient List Control is divided into 2 panes, the list pane and the preview pane. The list pane (the top pane) contains the ordered list of gradients. The preview pane (the bottom pane) contains a preview for the currently selected gradient. If the list selection is empty or contains more than 1 item, the preview pane is empty.
The Gradient List Control has 2 main functions. First, it is used to maintain the list of gradients. This includes adding gradients to the list, deleting gradients from the list, renaming gradients in the list, and moving gradients up/down in the list. These operations are performed by selecting 1 or more gradients in the list pane and executing one of the list editor commands. For example, to remove gradients from your list you would select the gradients to remove in the list pane and execute the Delete command.
The second function of the Gradient List Control is to preview a gradient. To edit a gradient, simply click on the preview pane or double-click the list entry to open the Gradient Editor.
Toolbar
All operations are performed using the toolbar buttons above the list. Place the mouse pointer over each button to see the associated command. The commands (in order) are:
-
New adds a new gradient to the bottom of the list.
-
Rename... displays the Rename dialog to rename the selected gradient. If the selection is empty or contains more than 1 gradient, the command is disabled.
-
Cut deletes the selected gradients from the list and places them on the clipboard.
-
Copy copies the selected gradients to the clipboard.
-
Paste pastes the gradients found on the clipboard into the list just before the 1st selected gradient or at the end of the list if the selection is empty. When you paste a gradient into the list, a copy of the gradient is made so that any changes to the gradient will not affect the original.
-
Delete deletes the selected gradients from the list.
-
Move Selection Up moves the selected gradients up in the list of gradients.
-
Move Selection Down moves the selected gradients down in the list of gradients.
-
Undo is used to undo the last change to the gradient list.
-
Redo is used to redo a change you previously undid!
-
Open Gradient Browser opens the Gradient Browser so you can copy/paste existing gradients from the Built-in Gradients or My Gradients into the list.
