Hi,<br><br>I have a very simple app running on Maemo 4.0 with a textbox and a button. As I click on the button, a callback function is invoked to show the content of the textbox. I don't know why the data pointer which is passed to callback function is sometimes NULL:<br>
- if I click on the textbox (a virtual keyboard shown below) and then click on the button, the callback function failed due to assertion of data pointer<br>- if I just click the button (don't focus on the textbox), the data pointer is not NULL, but the child of it is NULL.<br>
<br>I'm so confused. It didn't happen on Maemo 3.2 before.<br><br>Here's the code of 4 files (interface.*, callbacks.*) in my project /src/ui, I follow the structure of maemopad-2.1<br><a href="http://paste.org/index.php?id=2098">http://paste.org/index.php?id=2098</a><br>
<br>If you're interested in solving this problem, please help me out. Thanks very much!<br><br>Best regards,<br>Jakov<br><br>
