Get all objects from a GWT CellTable
CellTable has method getKeyProvider, which returns object containing data under ProvidesKey interface. You create ListDataProvider and pass it to cell table, so you can get that provider from cell table again at any time: ListDataProvider provider = (ListDataProvider)cellTable.getKeyProvider(); provider.getList().get(0); // get first Keyword ...
Events of multiple cells in single column
ButtonCell filters events on the first child element only: https://gwt.googlesource.com/gwt/+/2.6.1/user/src/com/google/gwt/cell/client/ButtonCell.java This is why you don't get an event when clicking the second button (note: the goal of that code is to make sure you clicked on the button, and not on blank space around the button; see https://gwt.googlesource.com/gwt/+/a0dc88c8be7408be9554f746eb1ec93798183a28) The easiest...
ListDataProvider.getList().remove doesn't use the KeyProvider
No it's not a bug and no it doesn't use the getKey implementation you provided for finding the element in that list, because that method is used for other operations. Bare with me... ListDataProvider uses a ListWrapper which implements the List interface and ListWrapper is backed by an ordinary List...
GWT : Render a hyperlink in a TextColumn of a CellTable
java,gwt,hyperlink,gwt-celltable
HyperTextCell hyperTextCell = new HyperTextCell(); Column<ServerKeyWord, ServerKeyWord> hyperColumn = new Column<ServerKeyWord, ServerKeyWord>( hyperTextCell) { @Override public ServerKeyWord getValue(ServerKeyWord keyWord) { return keyWord; } }; myCellTable.addColumn(hyperColumn); ...
Multiple ColumnSorting with AsyncDataProvider
See here for details. Basically view.getDataGridResults().getColumnSortList().get(0).getColumn() will return the column the user clicked on. If you want to get also the other columns (for example for multiple sorting) you have to check also the indices > 0 (i.e. get(1).getColumn()) Once you have the column you can check the direction by...
MGWT TapEvent from GWT AbstractCell?
java,javascript,gwt,mgwt,gwt-celltable
You cannot use mgwt touch events with GWT CellTable easily. If GWT-CellTable were more open, you could extend it, take the code related with touch events from Mgwt-CellTable and set the container of your extended class a touch capable widget. But that is impossible because you can not set nor...
How to Update Cell Table Footer Dynamically
You need to implement a custom Header and add it to the column which should contain that footer. For example: public class QuantityFooter extends Header<Number> { private final Number totalQty; public QuantityFooter(Number totalQty) { super(new NumberCell()); this.totalQty = totalQty; } public void setQuantity(Number totalQty) { this.totalQty = totalQty; } @Override...
JAVA GWT cell table action on control click
java,gwt,listener,gwt-celltable
You can use this: table.addCellPreviewHandler(new Handler<MyObject>() { @Override public void onCellPreview(CellPreviewEvent<MyObject> event) { if ("click".equals(event.getNativeEvent().getType())) { if (event.getNativeEvent().getCtrlKey()) { // CTRL button was pressed during the click } } } }); ...
stop click propagation of custom cell in CellTable
events,gwt,gwt-celltable,event-propagation
It's easier to cancel an event before it reaches the cell: table.addCellPreviewHandler(new Handler<Item>() { @Override public void onCellPreview(CellPreviewEvent<Item> event) { //do something event.setCancelled(true); } }); Note that CellPreviewHandler already monitors all events within a table. You can use it for your ClickEvent as well (with finer control like which column...
