[Gambas-user] Release of gambas 1.9.42

[Benoit Minisini]

Hi,

This release has many changes in the gb.qt component and gb.settings that will 
break your projects: 

* The Dialog.Filter syntax is now the same as the gb.form FileChooser control. 

* All Mode properties now uses the constants from the Select class. Other 
selection mode constants have been removed. The following classes are 
impacted: ListBox, ListView, GridView, TreeView, IconView, ColumnView. 
TableView will be modified too in the future.

* IconView GridX and GridY properties have been replaced by the GridWidth and 
GridHeight properties. 

* HBox, VBox, HPanel and VPanel have an AutoResize property now, which is not 
set by default, contrary to the old behaviour. The arrangement algorithm has 
changed a bit, so your forms may display differently.

* The Settings class now stores Window and SidePanel settings differently. 
This will mainly break the saved positions of IDE windows. 

You may have edit your form files by hand to fix the use of some properties. 
Or you can open them in the IDE, and fix the properties that have changed, 
and save them.

Otherwise, there are some enhancements in the IDE: 

* Optimizations in project loading: in the previous versions, the default 
value of a control property was calculated by creating an hidden control. Now 
no control is created, but the default value must be declared in the control 
hidden constant describing its properties (namely '_Properties'). I updated 
all _Properties everywhere, but if one has been forgotten, you may get false 
default values when inserting a control inside the form editor.

* Support for symbolic links. By using symbolic links, you can share forms, 
classes, modules or any file between two different projects. You cannot edit 
the file pointed by the symbolic link in the IDE.

* A better translation dialog, thanks to Charlie Reinl. You can now translate 
a project file by file. Charlie added some shortcuts: I just remove the 
description of the shortcuts from the tooltips. They should go in a help page 
on the wiki instead.

* The old file creation dialogs have been replaced by a new one.

There is a new DateChooser calendar control too. It replaces the DatePicker 
that was depending on KDE.

Here is the full ChangeLog:

-------------------------------------------------------------------------------

  default values in the '_Properties' constant.

  source file is automatically inserted at the beginning of the file.
* NEW: Old file creation dialogs have been removed, and replaced by a 
  unique one.

  experimental.
