Hi,
I am creating my own widgets library using gwt 2.5 for my application to be
used.But facing issues while creating this widget component.Widgets
creation will be like this-textbox with label,checkbox with label,datebox
with label,radio button with label.Here label field is common for all
widget creation.
See the below code,
/*basebox code which will create the default label with corresponding
component(widget)*/
public abstract class BaseBox extends FlowPanel{
protected Widget box;
private String title;
private String name;
Widget labelWidget;
private LabelBoxField boxLabel;
public BaseBox(String name){
this.name=name;
addMembers(name);
}
protected void addMembers(final String name) {
this.name = name;
box = createBox(name);
}
protected abstract Widget createBox(String name);
public void setTitle(String title) {
this.title=title;
labelWidget = createLabel(title);
}
/*code for creating label*/
protected Widget createLabel(final String title) {
if (title == null || title.isEmpty()
|| title.equals(Constants.EMPTY_STRING)) {
this.boxLabel = new LabelBoxField();
} else {
if (getIsHintButtonRequired()) {
this.boxLabel = new LabelBoxField(title,
getIsHintButtonRequired(),getRequired());
} else {
this.boxLabel = new LabelBoxField(title,getRequired());
}
}
boxLabel.setHorizontalAlignment(HasHorizontalAlignment.ALIGN_RIGHT);
return boxLabel;
}
public void showTitle(Boolean showTitle){
this.showTitle=showTitle;
}
/*this method will render the component before adding it to
main-panel----should not call this method implicitly*/
public void redraw(){
addStyleName(ROW_FLUID);
if(showTitle){
((LabelBoxField)labelWidget).getBoxLabel().setVisible(true);
}else{
if(labelWidget!=null){
((LabelBoxField)labelWidget).getBoxLabel().setVisible(false);
}
}
if(labelWidget!=null){
labelWidget.addStyleName(getStyleName(labelOrientation));
}
box.addStyleName(getStyleName(labelOrientation));
if(showTitle){
add(labelWidget);
}
add(box);
}
/**code for textbox which extends Basebox*/
public class TextItemBox extends BaseBox {
public TextItemBox(String name) {
super(name);
}
@Override
protected Widget createBox(String name) {
TextBox box = new TextBox();
box.setName(name);
return box;
}
}
/*code which create textbox and added to main-panel*/
TextBox txt=new TextBox("txtItem");
txt.setTitle("Enter the Name to Display");
txt.showTitle(false);
hp.add(txt);
First we create the widget by calling new TextBox() and we set the
properties like(setTitle,showAlignment,etc).After setting this property how
do we render the component again.Like for example in smartgwt after
creating the widget we set the properties,widgets render by itself without
calling any specific methods like redraw().How can this be achieved in
GWT?Please give suggestion?
