My experience converting a fair-sized project ... ~45,000 lines, using MyGWT RC2 and ExtGWT in Beta 3 ... was tedious, but not difficult. It took me about two days (20ish hours) to do it all myself - learn the new ExtGWT pieces and parts and get the app working 100%. I'd say the biggest time-sink for me personally was getting Trees working correctly....
Essentially nothing is hard to accomplish in the conversion process ... it's really just time-consuming, requires a lot of find/replacing then fine-tooth-combing. On that note, I compiled a document that contains some of the more basic changes, which is intended to help one of my colleagues convert his MyGWT-based app. This list is not organized well, not particularly comprehensive, and in some cases might be wrong with newer releases of ExtGWT, but I wanted to start some thread of cooperation here to make a good, readable list of changes for people who might still be converting, or thinking about doing so, as it seems silly for everyone to start in the dark every time.
Having said that, if someone knows about one that's already in the works/is pretty far along ignore me ^.^
MyGWT -> Ext GWT
Class Name Changes
- Shell == Window
- ShellManager == Window
- WidgetContainer == LayoutContainer
- Viewer == (ListStore<ModelData> || TreeStore<ModelData>)
- TableLayoutData == TableData
- implements Model == extends ModelData
- ListViewer == ListStore<ModelData>
-ViewerFilterTextBox == MyGWTUtils1_5.ViewerFilterTextBox<ModelData>
- ContentProvider (roughly equivalent to) StoreBinder --- subclasses are DataListBinder, TableBinder, TreeTableBinder, etc.
Method Name Changes, Other Find/Replace Candidates
- Shell.getContent() == NOTHING
- Shell.setText(...) == Shell.setHeading(...)
- *.close() == *.hide();
- *.open() == *.show();
- Dialog.setCloseOnButtonClick() == Dialog.setHideOnButtonClick()
- Viewer.applyFilters() == .applyFilters(String property)
- Window.open() == Window.show()
- new RowData(RowData.FILL_BOTH); == new RowData(1d, 1d);
- new RowData(RowData.FILL_HORIZONTAL); == new RowData(height, 1d);
- new RowData(RowData.FILL_VERTICAL); == new RowData(1d, width);
- *.setResize == .setResizable(boolean);
- *.setScrollable(boolean) == .setScrollMode(Scroll.*);
- *.setScrollEnabled == .setScrollMode(Scroll.*)
Other Changes
- If a style gets eaten by GXT, e.g. when you have a setIconStyle( <style> ), it must be followed by a !important,
e.g. .icon-start-here { background: url(../tango/places/start-here.png) no-repeat !important; }
- ButtonBar bar = new ButtonBar(<Alignment>) ==
bar = new ButtonBar();
bar.setButtonAlign(Style.HorizontalAlignment.RIGHT);
- *.getContent() == NOTHING
- *.getContainer() == NOTHING -- Things tend to extend Container, e.g. Window
- new List( Style.SINGLE|MULTI ); ==
list = new DataList();
list..setSelectionMode( SelectionMode.SINGLE|MULTI );
- new Layout().setType(Style.VERTICAL); ==
new Layout(Orientation.VERTICAL);
- layout(boolean force) -> layout()
- new BorderLayoutData(Style.*) == new BorderLayoutData(LayoutRegion.*)
- new ToolItem(Style.*) ... new ToolItem/TextToolItem/ToggleToolItem/SeparatorToolItem
- tree = new Tree( Style.CHECK); ==
tree = new Tree();
tree.setCheckable(true);
- TreeItem[] items = tree.getChecked() ==
TreeItem[] items = tree.getChecked().toArray( new TreeItem[0] );
-<T>.setToolTip( String title, String message ); ==
<T>.setToolTip( new ToolTipConfig( String title, String message ) );
- If center() is called on a Window before show() is called, an exception is thrown
- new MenuItem(Style.*) == new MenuItem();
