To specify the color scheme to use for semantic highlighting, select Tools > Options > Text Editor > Fonts & Color.
Generic highlighting is based on highlight definition files that are provided by the Kate Editor. You can download highlight definition files for use with Qt Creator. For more information about the definition files, see KDE-Files.org.
If you have a Unix installation that comes with the Kate Editor, you might already have the definition files installed. Typically, the files are located in a read-only directory, and therefore, you cannot manage them. Qt Creator can try to locate them and use them as fallback files, when the primary location does not contain the definition for the current file type. You can also specify the directory that contains preinstalled highlight definition files as the primary location.
When you open a file for editing and the editor cannot find the highlight definition for it, an alert appears. You can turn off the alerts. You can also specify patterns for ignoring files. The editor will not alert you if highlight definitions for the ignored files are not found.
To download highlight definition files:
- Select Tools > Options > Text Editor > Generic Highlighter.
- In the Location field, specify the path to the primary location for highlight definition files.
- Click Download Definitions to open a list of highlight definition files available for download.
- Select highlight definition files in the list and click Download Selected Definitions.
- Select the Use fallback location check box to specify the secondary location where the editor will look for highlight definition files.
- Click Autodetect to allow Qt Creator to look for highlight definition files on your system, or click Browse to locate them in the file system yourself.
- In the Ignored file patterns field, specify file patterns. You will not receive alerts if the highlight definitions for the specified files are not found.
- Click OK to save your changes.
Highlighting and Folding Blocks
Use block highlighting to visually separate parts of the code that belong together. For example, when you place the cursor within the braces, the code enclosed in braces is highlighted.
To enable block highlighting, select Tools > Options > Text Editor > Display > Highlight blocks.
Use the folding markers to collapse and expand blocks of code within braces. Click the folding marker to collapse or expand a block. In the figure above, the folding markers are located between the line number and the text pane.
To show the folding markers, select Tools > Options > Text Editor > Display > Display folding markers. This option is enabled by default.
When the cursor is on a brace, the matching brace is animated by default. To turn off the animation and just highlight the block and the braces, select Tools > Options > Text Editor > Display and deselect Animate matching parentheses.
