Java – how to make a cell non editable based on another cell value in an editable grid in GXT
•
Java
Hi, I'm using GXT 2.2 3. Create an editable grid I created the following:
List<String> eventList=new ArrayList<String>();
eventList.add("Mark/Modify Attendance");
eventList.add("Remove Attendance");
eventList.add("Modify Roster");
eventList.add("Mark OD");
eventList.add("Forgot To Checkin");
eventcombo = new SimpleCombo@R_510_2419@<String>();
eventcombo.setEmptyText("");
eventcombo.setTriggerAction(TriggerAction.ALL);
// EventCombo.setSelection(eventList);
CellEditor eventComboEditor = new CellEditor(eventcombo) {
public Object preProcessValue(Object value) {
if (value == null) {
return value;
}
return eventcombo.findModel(value.toString());
}
public Object postProcessValue(Object value) {
if (value == null) {
return value;
}
return ((ModelData) value).get("value");
}
};
eventcombo.setForceSelection(true);
eventcombo.setEmptyText("");
eventcombo.setTriggerAction(TriggerAction.ALL);
eventcombo.add(eventList);
ColumnConfig eventcolumn = new ColumnConfig();
eventcolumn.setId("event");
eventcolumn.setHeader("Event");
eventcolumn.setWidth(145);
eventcolumn.setMenuDisabled(true);
eventcolumn.setSortable(false);
/* */
// column.setEditor(new);
eventcolumn.setEditor(eventComboEditor);
configs.add(eventcolumn);
//rosterInOut-10
ColumnConfig rosterInOutcolumn = new ColumnConfig();
rosterInOutcolumn.setId("rosterInOut");
rosterInOutcolumn.setHeader("Old Roster");
rosterInOutcolumn.setWidth(70);
rosterInOutcolumn.setMenuDisabled(true);
rosterInOutcolumn.setSortable(false);
configs.add(rosterInOutcolumn);
Rostercombo = new SimpleCombo@R_510_2419@<String>();
CellEditor editor1 = new CellEditor(Rostercombo) {
public Object preProcessValue(Object value) {
if (value == null) {
return value;
}
return Rostercombo.findModel(value.toString());
}
public Object postProcessValue(Object value) {
if (value == null) {
return value;
}
return ((ModelData) value).get("value");
}
};

return new ColumnModel(configs);
Now I want to set the checkindate, checkintime, checkoutdate and checkouttime column cells to noneditable or disable values based on the value of the eventcombo box
How to do this in the listener of eventcombo Please give me some advice
I try the following code to disable and enable cells, but it disables cell fines But when disabled, if I choose another one, it won't be enabled again
Listener gt; gridAfterEditListener = new Listener>(){
@Override
public void handleEvent(GridEvent<AttendanceCaseCreationModel> be) {
AttendanceCaseCreationModel data = be.getModel();
String val = data.get("event");
if(val.equalsIgnoreCase("Remove Attendance")){
data.set("checkinDate","");
grid.getColumnModel().getColumnById("checkinDate").getEditor().disable();
grid.getStore().update(data);
grid.getView().refresh(true);
}
else {
data.set("checkinDate","");
grid.getColumnModel().getColumnById("checkinDate").getEditor().enable();
grid.getStore().update(data);
grid.getView().refresh(true);
}
}
};
grid.addListener(Events.AfterEdit,gridAfterEditListener);
Please suggest how to solve this problem
Solution
Consider disabling and enabling cells. I just hide and use CSS to display cells The following is my code, which can help me meet this requirement
GridCellRenderer<AttendanceCaseCreationModel> checkinRenderer=new GridCellRenderer<AttendanceCaseCreationModel>() {
@Override
public Object render(AttendanceCaseCreationModel model,String property,ColumnData config,int rowIndex,int colIndex,ListStore<AttendanceCaseCreationModel> store,Grid<AttendanceCaseCreationModel> grid) {
String color="pink";
if(eventcombo.getValue()!=null){
if(eventcombo.getRawValue().equalsIgnoreCase("Forgot To Checkin") ||
eventcombo.getRawValue().equalsIgnoreCase("Mark/Modify Attendance")){
color="pink";
}
else{
config.style=config.style+ ";visibility: hidden;";
}
}
config.style=config.style+ ";background-color:" + color + ";";
config.style=config.style+ ";display: block;";
Object value = model.get(property);
return value;
}
};
