This is a problem for the WWizard::field(WString name) method (see http://doc.trolltech.com/4.4/qwizard.html#field for information of what it does, WWizard blatantly copies QWizard :-) I can't think of a good way of getting the actual value instead of the default value (i. e. run-time value instead of compilation-time value). I might come with a solution or workaround when my brain gets some sleep. In fact, I might be doing something wrong because after the wizard finishes, the right text is output to stdout. I've uploaded a working version of WWizard to gitorious: http://gitorious.org/projects/wwizard/ It can be cloned with git clone git://gitorious.org/wwizard/mainline.git I've tested it with Wt 2.1.3. Currently, it needs Ext but in the future there will be an Ext and a non-Ext version, both generated using CMake scripting from the same source. You can see the problem by using WizardTest or WizardTest2 (the only difference is in WizardTest2 the code is organized in three separated methods, like in the Qt License Wizard example). Features missing: a lot :-), namely: * non-linear wizards * disable buttons if mandatory items are not completed * hide the "back" button in the first page and the "next" button in the last page (Wt shows a weird error about undefined properties!) * code clean-up * remove friend-ness where possible * many more I'd say it works fine as a basic wizard, though. -- Pau Garcia i Quiles http://www.elpauer.org (Due to my workload, I may need 10 days to answer) ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
