Graphical Explorer Options

Graph Options dialog box is divided into seven tabs.

General

Graph Options General tab

Scrolling / Absolute step

Determines the absolute step of graph image scrolling.

Scrolling / Relative step

Determines the relative step of graph image scrolling.

Scrolling / Relative

On scrolling Graph using arrow keys, the picture is moved in accordance with the screen size percentage set in Scrolling / Relative step.

Scrolling / Absolute

On scrolling Graph using arrow keys, the picture is moved in accordance with the number of Graph size units set in Scrolling / Absolute step.

In the Scrolling part you can set the manner of scrolling for the window in which the graph is displayed. If you select the option Relative, scrolling will be relative in relation to graph width for the value in the corresponding edit control. If you select the option Absolute, scrolling will be absolute for the number of pixels entered in the corresponding edit control.

Zooming / Relative step

Determines the relative step of graph image zooming.

Zooming / Maximal depth

Determines the maximum zooming depth, that is, the maximum number of zooming operations.

Zooming / Originated

Specifies whether the zooming will be carried out in relation to the starting node or to the currently visible part of the graph. The node will be placed on the left side of the screen, a third of the way down and half way across.

Reduced mode / Start Graph in reduced mode

Determines whether multiple edges between two nodes will be grouped.

Reduced mode / Display edge count in reduced mode

Determines if the number of grouped multiple edges in reduced mode will be displayed by the group edge.

Height

Initial node height

Show file name

Specifies whether the name of the source file in which the symbol displayed in the node is defined will be displayed.

Border type

Specifies whether node has shadow and shadow position relative to node.

Font

Specifies the font used for node text

Sample

Displays an example of a graph for the settings specified.

CHG Colors

Graph Options CHG Colors tab

Public background

Determines the background color of public functions in function graphs.

Public text

Determines the text color of public functions in function graphs.

Static background

Determines the background color of static functions in function graphs.

Static text

Determines the text color of static functions in function graphs.

Library background

Determines the background color of library functions in function graphs.

Library text

Determines the text color of library functions in function graphs.

Parameter background

Determines the background color of library functions in function graphs.

Parameter text

Determines the text color of library functions in function graphs.

Group background

Determines the background color of group nodes in Graphs.

Group text

Determines the text color of group nodes in Graphs.

Selected node

Determines the color of selected nodes in Graphs.

Selecting node

Determines the color of selecting nodes in Graphs.

Selected edge

Determines the color of selected edges in Graphs.

Selecting edge

Determines the color of selecting edges in Graphs.

Windows background

Determines the window background color of Call-Hierarchy graphs.

Breakpoint

Determines the breakpoint color of Call-Hierarchy graphs.

Execution point

Determines the execution point color of Call-Hierarchy graphs.

Color

Specifying the color of a particular element is carried out by clicking the button with the colored rectangle which opens the standard Windows Color dialog for color selection. Color change effects of a particular graph element can be viewed immediately in the Sample part. A button with a colored rectangle shows the current color of the element selected in the List Box. 

As the number of elements for which color can be set is large, DAC will take care of some of these tasks for you. That is, you will set public function node color, and DAC will on the basis of the color selected come up with a color one shade darker for global data nodes. The same applies for static and library data and functions.

Sample

Displays an example according to current settings.

Arranging Algorithm

Graph Options Arranging Algorithm tab

Minimized edge length

Determines the arranging algorithm type. The arranging algorithm prefers minimal distances between nodes.

Deep function calls hierarchy

Determines the arranging algorithm type. Call-Hierarchy Graph is arranged so that function nodes are arranged in levels. Deep hierarchy for function calls is preferred.

Library functions always on last level

Specifies that nodes representing library functions and data are always arranged at lowest graph level. This setting works only when Deep Function Calls Hierarchy arranging algorithm is selected.
