I have a widget that I render in a GWT cell, which extends the
AbstractCell, via the render function below. The column is created as below
with the getValue and the FieldUpdater (update) function being defined. The
intent is to set selected row to correspond to the clicked widget. However,
when I click on the widget, the onBrowserEvent function of the cell is not
called. I think this is happening because the widget in question contains a
FlexTable within it.
I verified this by setting a breakpoint in the function
AbstractCellTable.onBrowserEvent2 and noticed that the function does not
fire a cell event since the else if (section == getTableBodyElement())
return false. This is false because the section is a sub-section of the
table body element corresponding to the table that I inserted via the
widget.
Is there a way to pass the click in the inner table (widget) to the outer
cell table?
//Render function to add widget to cell
public void render(Context context, MyItem value, SafeHtmlBuilder sb) {
if (value != null) {
SafeHtml safeValue = SafeHtmlUtils.fromTrustedString(value
.getWidget().getElement().getString());
sb.append(safeValue);
}
}
//Creating the corresponding column, setting up the field update,
// and adding the column to cell table
// Create Cell
MyItemCell myItemCell = new MyItemCell();
// Create Column
Column<MyItem, MyItem> myItemColumn = new Column<MyItem, MyItem>(myItemCell) {
@Override
public MyItem getValue(MyItem object) {
return object;
}
};
// add field updater
myItemColumn.setFieldUpdater(new FieldUpdater<MyItem, MyItem>() {
@Override
public void update(int index, MyItem object, MyItem value) {
// This function, for some reason,
// is not getting called when I click
// on the widget corresponding to MyItem
MyDataTable.this.getSelectionModel().setSelected(object, true);
}
});
// Add column to table
this.getDataTable().addColumn(myItemColumn);
