Multiple drag and drop element without Interoperability

$

Hi all, I have a problem with my drag and drop. I'm not sure if it's an intended design or not but I didn't see anything about this on forums or javadoc. If you put, let's say, 2 listbox on a page. On both listbox you implement the drag and drop to reorder the list box. If you take the element from 1 listbox and hover it on the other listbox, you will have a green check mark to the left because the listbox is "droppable". But you don't want it to be there. Is there any way to check a onDrag or onOver event to check if it can actually be droppable by the good element? Thanks

Can't cause update of component visiblity in Window based on changed boolean property

$
0
0
For this example, I have a window that displays connection status. Either connected or disconnected. When I press the connect button I want the visibility of one groupbox of components to hide and another to appear. The actual implementation is more complex, but here is a trimmed down example. I'm hoping / guessing I'm missing something simple in configuring my bindings or @NotifyChange() calls. When the window is displayed it shows a Disconnected message and a connect button. Pressing the connect button calls through to the connect() command and the connected properties value gets updated from false to true. (I can see this through the debugger) However the view does not update to hide the upper groupbox and display the lower groupbox. The label that is @bind(vm.connected) does not update either. If I change the initial value of connected from false to true, then the first groupbox is hidden and the second group box is displayed on initial viewing, however it will not swap back. What am I missing? Help much appreciated. Thanks, Derek Zul file: View Model: package test; import org.zkoss.bind.annotation.Command; import org.zkoss.bind.annotation.NotifyChange; public class TestVM { boolean connected = false; public boolean isConnected() { return connected; } public void setConnected(boolean connect) { this.connected = connect; } @NotifyChange("connected") @Command public void connect() { setConnected(true); } @NotifyChange("connected") @Command public void disconnect() { setConnected(false); } }

Extend Grid in Java

I'm trying to expand a Grid in Java but I'm being unsuccessful. I've crated a zul template that looks like this: and my Java class looks like this: public class ShotDescriptionGrid extends Grid implements IdSpace { /** * */ private static final long serialVersionUID = 1L; @Wire Label vaccineLabel; @Wire Textbox vaccineName; @Wire Label lotLabel; @Wire Textbox lotValue; @Wire Label dateLabel; @Wire Textbox dateValue; @Wire Label reactionsLabel; @Wire Textbox reactionsText; @Wire Label observationsLabel; @Wire Textbox observationsText; /** * */ public ShotDescriptionGrid(String vaccineLabel, String vaccineName, String lotLabel, String lotValue, String dateLabel, String dateValue, String reactionsLabel, String reactionsText, String observationsLabel, String observationsText) { Executions.createComponents("/WEB-INF/grids/descriptionShots.zul", this, null); Selectors.wireVariables(this, this, null); Selectors.wireEventListeners(this, this); setHeight("100%");setWidth("100%"); setStyle("overflow:auto;"); this.vaccineLabel.setValue(vaccineLabel); this.vaccineName.setValue(vaccineName); this.lotLabel.setValue(lotLabel); this.lotValue.setValue(lotValue); this.dateLabel.setValue(dateLabel); this.dateValue.setValue(dateValue); this.reactionsLabel.setValue(reactionsLabel); this.reactionsText.setValue(reactionsText); this.observationsLabel.setValue(observationsLabel); this.observationsText.setValue(observationsText); } Besides the obvious extensive parameters in the constructor (this was a basic approach to see if it'd work) problem my variables aren't being wired in the component. Am I doing something wrong or I can't extend a Grid in Java? Thanks for help.

Zk Any Interface with setModel method

I have a method with a lot of bussiness logic and the first parameter is a Combobox i need the exact same logic but now with a chosen box i think if combobox and chosenbox would share a interface with setModel method would solve my problem something like public interface ModelAble { public void setModel(ListModel> model); } Would solve my problem using ModelAble in my model and Combobox and Chosenbox would work very easy but any interface works for both? i need setModel method because is the way i put the data into both Components any workaround.

I have look many documentation about "Upload Multiple Files at Once", but all I can find is telling me: Repeatedly select files, and then upload once. I wonder in ZK how can I select multiple files just one time( meaning one opration, without repeatedly ), and then upload those files at once. Thank you. I really need to find out this answer.
