Advanced configuration options

Use the Advanced tab to configure the image cache, the stored settings, and the buttons style.

The Advanced tab consists of these sections:

Changes are not applied until Apply is clicked. To discard changes, click Restore.


The Genero Desktop Client stores remotely-retrieved files, whether they are retrieved using HTTP(S) or from the runtime system. See Retrieving and managing files for more information on the retrieving of files. Web component widgets, Universal Rendering, and the END_URL application end (where you specify the user-agent to redirect to a URL at web application end) all use webviews, which are also stored locally.

For all these, the GDC uses a disk cache. Files are stored in the AppCacheDir directory (see GDC configuration file directories). When the cache is full, files which have not been recently used are removed from the cache.


The cache can prevent the developer from seeing changes in the Web component, as old versions of the files saved in the cache may be used instead of downloading the latest versions from the server. To force the webview to download the latest versions, users need to clear the cache.

The Clear button clears the cache.


It is recommended to close any applications displaying a webview prior to clearing the cache, as it will wipe all cache entries from the disk.

When configuration settings for the cache in GDC are modified in one monitor, the settings are applied to all monitors for a user. For example, if you clear the cache in one monitor, it is also cleared in all other monitors.

Stored settings

Stored settings refer to the storage of window and widget properties such as size, table layout (column order, width, sorting, and so on) on the platform where the GDC sits. These settings are stored for each program executed, and the settings are used when the program relaunches, so that the end user sees the same display when the application starts as they had when the application last terminated.

Select Disable to temporarily disable stored settings. When disabled, all widgets and windows use their defaults for size and display. The stored settings are not cleared (they remain on disk), but they are not used, nor are they updated on application end.

Select Read only to read the stored settings when forms are loaded, but not update the stored settings when the forms are closed. For example, assume the window of an application has been saved in maximized state. With the Read only option activated, you can resize the window or do whatever you want with the application; yet when you exit and restart the application it will be returned to its maximized state.

The Clear button clears all stored settings. This button is disabled if there are no stored settings to clear.

It is strongly recommend that you clear stored settings when migrating to a new major release of GDC. You might otherwise encounter some side effects due to corrections or new functionality.

Dictionary list

The dictionary list relates to the spellchecking feature for Web components.

Spellchecking of Web components is based on dictionaries stored in:
  • GDCDIR/bin/qtwebengine_dictionaries on Windows® and Linux® systems.
  • GDCDIR/Contents/Resources/qtwebengine_dictionaries on macOS™ systems.
The dictionaries are .bdic files. GDC populates the Select Language context menu for spellchecking of Web components based on the list of .bdic files found in this directory. GDC creates this list on startup; click Refresh to update the list based on the latest contents of the directory.

For the .bdic files packaged with GDC, a transposition of the file name is made to display the name of the language. For example, instead of "it_IT" you will see "Italian". For all added .bdic files, the name of the file is used in the context menu.

Buttons style

The look-and-feel of the buttons in the GDC monitor and its dialogs (the shortcut wizard, login, about box, debug console, and so on) can be customized to match the look-and-feel of a regular Genero application. Customization options include:
  • none - Displays buttons as raised buttons, without icons.
  • with icons - Displays buttons as raised buttons with icons.
  • flat, with icons - Displays buttons as flat (non-raised) buttons with icons.
