Can I use DI in widget cells,because it doesn't seem to be working with me?

[Mohammad Al-Quraian]

I was just wondering if DI can be used in cell widget or not? I tried constructor and method injection but it seems that DI is never fired up on cell widgets.

You can use DI everywhere object creation can be done by the DI container (for instance, it means using @UiField(provided=true) or @UiFactory for UiBinder).

So the question is: how are your cells instantiated?

Good question, I don't even know how they are instantiated!

I just got a CellList declared as:

private final CellList<Presentable> cellList = new CellList<Presentable>(new TileCell());

and call this method to update the list:

public void setTilesStartingAt(int start, List<Presentable> tiles) {

cellList.setRowData(start, tiles);

}

How are they instaniated, sorry I just started learning about cells.

Thanks Thomas

'new' TileCell. If you have dependencies in TileCell that you want to be automatically injected, then have TileCell injected into your class as well.

It's not about cells, it's about Java. DI doesn't magically plug into the compiler; GIN et al. only generate code that you could have written yourself.

Start to learn about DI "by hand" (ever seen the ClientFactory from the GWT tutorials?) to "get" the concept, then use a tool that will generate that ClientFactory for you (ClientFactory will be an interface extending Ginjector if you use GIN).

Alternatively, look at the code generated by GIN (pass -gen to the compiler or DevMode)
