Here is a list of user-visible changes in Qt from 1.33 to 1.40.
|
||
|
|
|
||
|
|
Qt 1.40 supports drag and drop, with a simple, platform independent
|
||
|
|
API. There are eleven new widget classes in 1.40. Asynchronous I/O
|
||
|
|
support is now in the official Qt API.
|
||
|
|
|
||
|
|
Since Qt no longer supports any platforms that only supports 8.3
|
||
|
|
format file names, the file names of the Qt source and include files
|
||
|
|
have been made simpler. #include <qcombobox.h> instead of qcombo.h,
|
||
|
|
etc. The old names are still present for compatibility.
|
||
|
|
|
||
|
|
The new Qt Xt/Motif Extension allows Qt widgets and applications to
|
||
|
|
coexist with old Xt/Motif-based applications and widgets.
|
||
|
|
|
||
|
|
There are more than one hundred new functions added to existing
|
||
|
|
classes and, as usual, we fixed some bugs, made some more speedups,
|
||
|
|
and improved the documentation.
