Enhancment suggestion: API ListGridField.setHoverWidth(int width)

[Blama]

Hi Isomorphic,

I just noted that I can't define the Tooltip/Hover item width per ListGridField, as it extends DataClass and I can't find a way to get to my generated Canvas for the ListGridField, neither from ListGridField nor from ListGrid.
I think it might be a good idea to add setHoverWidth (int width), as you already have setHoverCustomizer (HoverCustomizer hoverCustomizer)

Best regards,

Hi Isomorphic,

I'm using current 5.0p (v10.0p_2015-05-06), which has ListGridField.setHoverWidth() (see also this thread).

But for me this seems not to work, see this BuiltInDS-based showcase:

package com.smartgwt.sample.client;

import com.google.gwt.core.client.EntryPoint;
import com.smartgwt.client.core.KeyIdentifier;
import com.smartgwt.client.data.DataSource;
import com.smartgwt.client.data.SortSpecifier;
import com.smartgwt.client.types.SortDirection;
import com.smartgwt.client.util.PageKeyHandler;
import com.smartgwt.client.util.Page;
import com.smartgwt.client.util.SC;
import com.smartgwt.client.widgets.IButton;
import com.smartgwt.client.widgets.events.ClickEvent;
import com.smartgwt.client.widgets.events.ClickHandler;
import com.smartgwt.client.widgets.grid.HoverCustomizer;
import com.smartgwt.client.widgets.grid.ListGrid;
import com.smartgwt.client.widgets.grid.ListGridField;
import com.smartgwt.client.widgets.grid.ListGridRecord;
import com.smartgwt.client.widgets.layout.VLayout;

public class BuiltInDS implements EntryPoint {
	private VLayout vL;
	private TestGrid tG;

	public void onModuleLoad() {
		KeyIdentifier debugKey = new KeyIdentifier();
		debugKey.setCtrlKey(true);
		debugKey.setKeyName("D");

		Page.registerKey(debugKey, new PageKeyHandler() {
			public void execute(String keyName) {
				SC.showConsole();
			}
		});

		vL = new VLayout(5);
		vL.setPadding(20);
		vL.setWidth100();
		vL.setHeight100();
		tG = new TestGrid();

		IButton reload = new IButton("Reload");
		reload.addClickHandler(new ClickHandler() {
			@Override
			public void onClick(ClickEvent event) {
				vL.removeChild(tG);
				tG.markForRedraw();
				tG = new TestGrid();
				vL.addMember(tG, 0);
			}
		});
		vL.addMembers(tG, reload);
		vL.draw();
	}

	private class TestGrid extends ListGrid {
		public TestGrid() {
			super(DataSource.get("animals"));

			ListGridField commonName = new ListGridField("commonName");
			commonName.setHoverCustomizer(new HoverCustomizer() {
				@Override
				public String hoverHTML(Object value, ListGridRecord record, int rowNum, int colNum) {
					String descStr = record.getAttribute("information");
					if (descStr == null)
						descStr = "[no information]";
					return descStr;
				}
			});
			commonName.setHoverDelay(100);
			commonName.setShowHover(true);
			commonName.setHoverWidth(800);

			ListGridField scientificName = new ListGridField("scientificName");
			scientificName.setHoverCustomizer(new HoverCustomizer() {
				@Override
				public String hoverHTML(Object value, ListGridRecord record, int rowNum, int colNum) {
					String descStr = record.getAttribute("information");
					if (descStr == null)
						descStr = "[no information]";
					return descStr;
				}
			});
			scientificName.setHoverDelay(100);
			scientificName.setShowHover(true);

			ListGridField lifeSpan = new ListGridField("lifeSpan");
			ListGridField status = new ListGridField("status");
			ListGridField diet = new ListGridField("diet");
			ListGridField information = new ListGridField("information");

			setAutoFetchData(false);
			setCanHover(true);
			// setHoverWidth(1600);
			setFields(commonName, scientificName, lifeSpan, status, diet, information);
			setSort(new SortSpecifier[] { new SortSpecifier(lifeSpan.getName(), SortDirection.ASCENDING),
					new SortSpecifier(diet.getName(), SortDirection.DESCENDING) });
			fetchData();
		}
	}

}

See hoverWidth for field commonName. Also, if you set a different hoverWidth on the ListGrid-level, the ListGridField-hoverWidth is unused/overwritten.
