我使用Ext-GWT在小部件上設置了邊界佈局。有沒有辦法可以自動設置「分割」位置?原因是,如果用戶調整頁面上的控件(不一定是分割控件所在的父控件),我想將分割值設置爲特定的百分比值(如30%)。如何才能做到這一點?如何以編程方式在GXT中設置BorderLayout的分割位置?
這裏的現有代碼:
import com.extjs.gxt.ui.client.Style.LayoutRegion;
import com.extjs.gxt.ui.client.util.Margins;
import com.extjs.gxt.ui.client.widget.ContentPanel;
import com.extjs.gxt.ui.client.widget.LayoutContainer;
import com.extjs.gxt.ui.client.widget.layout.BorderLayout;
import com.extjs.gxt.ui.client.widget.layout.BorderLayoutData;
import com.google.gwt.user.client.Element;
public class BorderLayoutExample extends LayoutContainer {
setSplitPositionTo(float percentage) {
// TODO: How to do this?
}
protected void onRender(Element target, int index) {
super.onRender(target, index);
final BorderLayout layout = new BorderLayout();
setLayout(layout);
setStyleAttribute("padding", "10px");
ContentPanel west = new ContentPanel();
ContentPanel center = new ContentPanel();
//uncomment this section if you dont want to see headers
/*
* west.setHeaderVisible(false);
* center.setHeaderVisible(false);
*/
BorderLayoutData westData = new BorderLayoutData(LayoutRegion.WEST, 150);
westData.setSplit(true);
westData.setCollapsible(true);
westData.setMargins(new Margins(0,5,0,0));
BorderLayoutData centerData = new BorderLayoutData(LayoutRegion.CENTER);
centerData.setMargins(new Margins(0));
add(west, westData);
add(center, centerData);
}
}
