• How to set input focus to a shown dialog in Qt?

  - by Jake Petroules

  In a button click slot, I create and exec() a dialog with a NULL parent. Inside the dialog's constructor, I have: this->activateWindow(); this->raise(); this->setFocus(); The dialog is application modal and has strong focus. However, it does NOT respond to keyboard events until I click on it. How do I make the dialog get focus without having to click it?

• Exposing boost::scoped_ptr in boost::python

  - by Rupert Jones

  Hello, I am getting a compile error, saying that the copy constructor of the scoped_ptr is private with the following code snippet: class a {}; struct s { boost::scoped_ptr<a> p; }; BOOST_PYTHON_MODULE( module ) { class_<s>( "s" ); } This example works with a shared_ptr though. It would be nice, if anyone knows the answer. Thanks

• Dynamically creating objects at runtime that inherit from a base class

  - by Homeliss

  I am writing a game editor, and have a lot of different "tool" objects. They all inherit from BTool and have the same constructor. I would like to dynamically populate a toolbox at runtime with buttons that correspond to these tools, and when clicked have them create an instance of that tool and set it as the current tool. Is this possible, and if so will it be better/easier than creating those buttons by hand?

• How to add multiple handlers to an attached event in XAML ?

  - by Gishu

  I want to add 2 handlers to a particular event like shown above. However this won't compile - 'attribute can be set more than once'. I have multiple methods because they do different things (are named appropriately). e.g. the first handler has nothing in common with the second. My other option was to kludge a SetFlagForCursorTrackingAndCheckForViewLink method - which is "Yech!". Any ideas ?

  Is it possible to use annotations to map a default value for a column? eg. I have a column named 'date' which is supposed to be '0000-00-00 00:00:00' if not date is explicitly given. I know I can add this to the ctor of the Entity. But then the default behavior will no be present in my database backend. (eg. Default column in mysql)

• GetRef to capture methods?

  - by Thom Smith

  I've just discovered VBScript's GetRef function, which gets a reference to the function named by its argument. Is there any way to get a reference to a method in this way? I have a hunch that VBScript doesn't offer the sophistication of binding needed to do so, but it would sure be nice.
