Parameters:
scheme - The instance of SyntaxScheme to use.
See Also:
getSyntaxScheme()

setTemplateDirectory

public static boolean setTemplateDirectory(java.lang.String dir)
If templates are enabled, all currently-known templates are forgotten and all templates are loaded from all files in the specified directory ending in "*.xml". If templates aren't enabled, nothing happens.

Parameters:
dir - The directory containing files ending in extension .xml that contain templates to load.
Returns:
true if the load was successful; false if either templates aren't currently enabled or the load failed somehow (most likely, the directory doesn't exist).
See Also:
getTemplatesEnabled(), setTemplatesEnabled(boolean), saveTemplates()

setTemplatesEnabled

public static void setTemplatesEnabled(boolean enabled)
Enables or disables templates.

Templates are a set of "shorthand identifiers" that you can configure so that you only have to type a short identifier (such as "forb") to insert a larger amount of code into the document (such as:

   for (<caret>) {

   }
 
Templates are a shared resource among all instances of RSyntaxTextArea; that is, templates can only be enabled/disabled for all text areas globally, not individually, and all text areas have access of the same templates. This should not be an issue; rather, it should be beneficial as it promotes uniformity among all text areas in an application.

For more flexible boilerplate code insertion, consider using the TemplateCompletion class in the AutoComplete add-on library.

Parameters:
enabled - Whether or not templates should be enabled.
See Also:
getTemplatesEnabled()

setTabLineColor

public void setTabLineColor(java.awt.Color c)
Sets the color use to paint tab lines. This method fires a property change event of type TAB_LINE_COLOR_PROPERTY.

Parameters:
c - The color. If this value is null, the default (gray) is used.
See Also:
getTabLineColor(), setPaintTabLines(boolean), getPaintTabLines()

setUseFocusableTips

public void setUseFocusableTips(boolean use)
Sets whether "focusable" tool tips are used instead of standard ones. Focusable tool tips are tool tips that the user can click on, resize, copy from, and clink links in. This method fires a property change event of type FOCUSABLE_TIPS_PROPERTY.

Parameters:
use - Whether to use focusable tool tips.
See Also:
getUseFocusableTips(), FocusableTip

setUseSelectedTextColor

public void setUseSelectedTextColor(boolean use)
Sets whether selected text should use the "selected text color" property (set via JTextComponent.setSelectedTextColor(Color)). This is the typical behavior of text components. By default, RSyntaxTextArea does not do this, so that token styles are visible even in selected regions of text. This method fires a property change event of type USE_SELECTED_TEXT_COLOR_PROPERTY.

Parameters:
use - Whether to use the "selected text" color when painting text in selected regions.
See Also:
getUseSelectedTextColor()
