Body
I am using a Flex 4 spark TextArea and I implemented a search field. I use the following code to highlight the searched text in the TextArea: <pre><code>private function findAndHighlightText():void { var text:String = findTextInput.text; var beginIndex:int = scriptSourceTextArea.text.indexOf( text, m_lastFoundIndex ); if (beginIndex == -1 && m_lastFoundIndex > 0) { // We are at the end, search back from the begin Alert.show( resourceManager.getString( 'groovyresources', 'search.at.end' ), resourceManager.getString( 'groovyresources', 'find' ) ); m_lastFoundIndex = 0; beginIndex = scriptSourceTextArea.text.indexOf( text, m_lastFoundIndex ); } if (beginIndex != -1) { var endIndex:int = beginIndex + text.length; m_lastFoundIndex = endIndex; scriptSourceTextArea.selectRange( beginIndex, endIndex ); scriptSourceTextArea.scrollToRange( beginIndex ); } else { Alert.show( resourceManager.getString( 'groovyresources', 'search.not.found', [text] ), resourceManager.getString( 'groovyresources', 'find' ) ); } } </code></pre> The most important is the method <code>selectRange</code> on the TextArea. This highlights the text in the TextArea, but I would like to use a different color. I can change the highlight color for manual selection by applying the CSS style <code>focused-text-selection-color</code> (See <a href="http://www.kirupa.com/forum/showthread.php?354479-Change-highlight-color-for-text-fields" rel="nofollow">http://www.kirupa.com/forum/showthread.php?354479-Change-highlight-color-for-text-fields</a>), but this does not change the color for the programmatic selection. UPDATE: The color does not change for the programmatic selection because the TextArea does not have the focus at that moment. So I need to find the unfocused selection color CSS name.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
