Different autoFit for different ListGridFieldType

[matus_b]

Hi Isomorphic,
can you please explain different auto-fitting behaviour when the ListGridField type is set to DATE and to TEXT?

Modified showcase com.smartgwt.sample.showcase.client.grid.datatypes.GridDataTypesDateSample

final ListGrid countryGrid = new ListGrid();
countryGrid.setWidth(700);
countryGrid.setHeight(224);
countryGrid.setShowAllRecords(true);
countryGrid.setCanEdit(true);
countryGrid.setEditEvent(ListGridEditEvent.CLICK);
countryGrid.setModalEditing(true);

// AutoFit is set
countryGrid.setAutoFitFieldWidths(true);
countryGrid.setAutoFitWidthApproach(AutoFitWidthApproach.BOTH);

ListGridField countryCodeField = new ListGridField("countryCode", "Flag", 50);
countryCodeField.setAlign(Alignment.CENTER);
countryCodeField.setType(ListGridFieldType.IMAGE);
countryCodeField.setImageURLPrefix("flags/16/");
countryCodeField.setImageURLSuffix(".png");
countryCodeField.setCanEdit(false);
ListGridField nameField = new ListGridField("countryName", "Country");
nameField.setWidth(50);

// We test this field
ListGridField independenceField = new ListGridField("independence", "Nationhood");
//independenceField.setType(ListGridFieldType.TEXT);
independenceField.setType(ListGridFieldType.DATE);
independenceField.setWidth("*");

countryGrid.setFields(new ListGridField[] {countryCodeField, nameField, independenceField});

canvas.addMember(countryGrid);

// Problem occurs only when we set data after the grid is drawn!
Button button = new Button("Set data");
button.addClickHandler(new ClickHandler() {
    @Override
    public void onClick(ClickEvent event) {
        countryGrid.setData(CountrySampleData.getRecords());
    }
});
canvas.addMember(button);

When independenceField is set to TEXT:

OnDraw:

OnSetData:


When independenceField is set to DATE:
OnDraw:

OnSetData:


What should be the correct way for ListGridField of type DATE to honour width "*"? We want it to behave the same as field of type TEXT.

Thanks
Matus

Tested on:
SmartClient Version: v10.0p_2018-03-14/LGPL Development Only (built 2018-03-14)
GC Version 65.0.3325.162 (Official Build) (64-bit)

Since date values in a grid are generally rendered all the same size, we skip auto fitting on such fields for performance reasons. This is all covered in the docs - see autoFitDateFields, getDefaultFieldWidth(), etc.

Ok, I missed that docs.
We achieved the grid without empty space with:

countryGrid.setAutoFitFieldsFillViewport(true);
countryGrid.setAutoFitExpandField("independence");
