| Qt 3.0 Beta6 is not binary compatible with Beta5; any programs linked |
| against Beta5 must be recompiled. |
| |
| Below you will find a description of general changes in the Qt |
| Library, Qt Designer and Qt Assistant. Followed by a detailed list of |
| changes in the API. |
| |
| |
| The Qt Library |
| ======================================== |
| |
| QCom postponed |
| -------------- |
| |
| Previous Qt 3.0 betas introduced a module called QCom that provides a |
| COM-like component system. The feedback we received on this module |
| during the 3.0 beta phase has been mixed. Many users think this module |
| lacks the intuitiveness and compactness that they have learned to |
| expect from a Qt API. Therefore, we have made the difficult decision |
| to withdraw the QCom API from the Qt 3.0 release. We will continue to |
| develop this API until it is evolved enough for our customers, and |
| will include the improved version in a later release. |
| |
| We apologize for any inconvenience the QCom API change has |
| caused. This decision was made as part of our ongoing efforts to |
| maintain the soundness and quality of Qt. |
| |
| Please note that the new plugin functionality in 3.0 will still be |
| provided. This includes using custom widgets in Qt Designer, as well |
| as runtime addition of styles, codecs, SQL drivers, and image format |
| handlers. This functionality is now available through a substantially |
| simplified API. |
| |
| Also also note that it will still be convenient to add custom plugin |
| capabilities to Qt 3.0 applications, since the new QLibrary class will |
| still be available. This class takes care of the low-level, |
| platform-dependent issues regarding loading of DLLs and obtaining |
| pointers to the functions exported by the DLLs. |
| |
| |
| Qt Designer |
| ======================================== |
| |
| - Improvements to the Designer reference manual. |
| |
| - Improved the C++ code indenter in the editor for numbers and |
| handling of parenthesis. |
| |
| |
| Qt Assistant |
| ======================================== |
| |
| - Added a context menu with common commands. |
| |
| - Allow multiple windows to be opened and added the common shortcut |
| that Shift+Click on a link opens the link in a new window. |
| |
| |
| Qt Functions |
| ======================================== |
| |
| QAccel |
| ------ |
| |
| - Try harder to ensure that accelerators continue to work when a top |
| level widget is reparented into another window. |

| color could not be allocated. |
| - win32 only: improve color allocation on 8bit displays, e.g. when |
| using a terminal server. |

| |
| New function: |
| virtual void setLineEdit( QLineEdit *edit ); |
| |

| -------- |

| compiler to optimize the number of conflicts as the location of a vtable |
| is now known. |
