Hi Sebastian,
I added the setting: { ... } declaration to the custom.Application class,
but the error happens before the Application class is loaded:
When I want to define a custom IconTheme, the Settings are read in the
icons: { ... } section of the theme and this is executed before the
Application class is loaded:
qx.Theme.define("custom.MyIconTheme",
{
title : "My Icon Theme",
icons :
{
uri : qx.core.Setting.get("custom.resourceUri") + "/icon_path" // This
line is evaluated before the Application class is loaded
}
});
I understand the settings feature that it is possible to define settings
before the application is loaded, to avoid hardcoding in the Application
class and the window.qxsettings mechanism exactly does this, but
unfortunately only the value and not the defaultValue is set.
Or is there another preferred way to define the uri of my IconTheme?
Regards,
Markus
