Display Dialogs and Views

Selective Display Dialog

The Selective Display dialog (Display → Selective Display or selective_display command) allows you to activate Selective Display and choose the regions in your code that you want to display or hide. Each region contains settings that are specific to that region. The dialog also contains static options for expanding. See Selective Display for more information about working with this feature.

Search Text

Select Search text to specify a search string and display lines containing the search string specified or lines not containing the search string specified. Click the right-pointing arrow button to the right of the field to display a menu containing specific search syntax options such as Character in Range, Beginning of Line, and Decimal Digit. The following settings are available:

Match case - When checked, a case sensitive search is performed.
Match whole word - When checked, a word search is performed. Before a search is considered successful, the characters to the left and right of the occurrence of the search string found are checked to be non-word characters. The default word characters are [A-Za-z0-9_$] and may be changed by using the Word chars field on the language-specific General options screen (see Language-Specific General Options).
Regular expression - When checked, a regular expression search is performed. See Find and Replace with Regular Expressions for more information.
Reset selective display - When checked, all lines are made visible and Plus and/or Minus bitmaps are removed before a search is performed.
Hide matched lines - When checked, lines containing the search pattern are hidden.

Function Headers

Select Function headers to display only function headings and optional function heading comments. The following settings affect how comments before function headings are handled:

Show comments - When checked, comments above function headings are displayed as if they were part of the function heading.
Collapse comments - When checked, comments above function headings are visible but multi-line comments will require that you expand them to see all comments.

When both options are off, comments will not be visible at all, making it difficult to copy or move functions and comments.

Preprocessor Directives

Select Preprocessor directives to display a source file as if it were preprocessed according to the define values you specify. If you do not remember your defines, use the Scan for Defines button. The following settings are available:

Defines - Specifies defines and optional values used when you select the Preprocessor Directives option on the Selective Display dialog box. The syntax is:
```
name1 [=value1] name2 [=value2]
```
For example:
```
WIN32S VERSION=4
```
Warning if Not Defined - If on when you preprocess your source, a message box is displayed for each define found in an expression which does not have a value.
Scan for Defines - Searches for define variables in the current source file and lets you specify values. Resulting values are placed in the Defines combo box.

Multi-Level

Select Multi-levelto set multiple levels of selective display based on braces or indent. The following settings are available:

Braces - When on, multiple levels of selective display are set to correspond to curly brace nesting levels.
Indentation - When on, multiple levels of selective display are set to correspond to indentation levels.
Limit levels - When too many nested levels of selective display get confusing, place a limit on the maximum number of nested levels. Nesting deeper than this specified level is ignored.

Paragraphs

Select Paragraphs to display the first line of each paragraph. A paragraph is defined by a group of lines followed by one or more blank lines.

Hide Selection

Select Hide selection to hide the lines in the current selection.

Expansion Options

The following expansion options can be applied for each region:

Expand sub-levels - When on, expanding hidden lines expands all nested hidden lines.
Collapse sub-levels - When on, expanding hidden lines collapses all nesting hidden lines.
Remember sub-levels - When on, expanding hidden lines displays nested hidden lines the way they were last displayed.
