but when i'mm trying to drag the window it doesn't drag it
i tried a simpler class with jnothing that works fine but when i call this window it doesn't drag
StatusWindow statusWindow = null;
void Start(){
statusWindow = new StatusWindow();
}
public Rect windowRect = new Rect(20, 20, 120, 50);
void OnGUI() {
windowRect = GUI.Window(0, windowRect, DoMyWindow, "My Window");
statusWindow.Draw (100, 100, 100, 100);
}
void DoMyWindow(int windowID) {
GUI.Button(new Rect(10, 20, 100, 20), "Can't drag me");
GUI.DragWindow();
}
If anyone who knows much about Unity GUI can help that would be great

I have a Listview and Click Events in the respective listItems and need to get result back from the click events and populate on the List.
My BaseAdapter class is
public class RemnantListAdapter : BaseAdapter<InventorySlabs>
{
private PartialInventory context;
private List<InventorySlabs> RemnantList;
public RemnantListAdapter(PartialInventory partialInventory, List<InventorySlabs> remnantList)
{
this.context = partialInventory;
this.RemnantList = remnantList;
}
public override InventorySlabs this[int position]

public override long GetItemId(int position)
{

}
public override int ViewTypeCount
{
get
{
return Count;
}
}
public override int GetItemViewType(int position)
{
return position;
}
private class remnantHolder : Object
{
public Button EditRemnant1;
public TextView Remnant1 = null;
public TextView Rem_StockNMaterial1 = null;
public TextView Rem_Dimensions1 = null;
public TextView Rem_Status1 = null;

public override View GetView(int position, View convertView, ViewGroup parent)

MainActivity.SaveLogReport(className, methodName, ex);
}
convertView.Tag = holder;
}
else
{
holder = (remnantHolder)convertView.Tag;
}
return convertView;
}
public void ActivityResult(int requestCode, Result resultCode, Intent data)
{
switch (requestCode)
{
case 1:
if (data != null)
{
try

In my Main Activity
I am calling the Result as
protected override void OnActivityResult(int requestCode, Result resultCode, Intent data)
{
remnantListAdapter.ActivityResult(requestCode, resultCode, data);
}
After editing the details in Edit view of the ListItem and close the Popup, I am not knowing how to Pass the Values to the Holder to Update in Listview.
You could pass the positon to the new activity in the click event and pass it back with the result intent.
For example:
holder.EditRemnant1.Click += delegate (object sender, System.EventArgs args)
{
if (remnantModel != null)
{
Intent intent = new Intent(context, typeof(EditRemnant));
intent.PutExtra("OpenPopType", 2);
intent.PutExtra("SlabNo", remnantModel.ExtSlabNo);
intent.PutExtra("Position", position );
context.StartActivityForResult(intent, 1);
}
};
And in the new activity:
protected override void OnCreate(Bundle savedInstanceState)
{
Intent intent = Intent;
var position =intent.GetIntExtra("Position", -1);
base.OnCreate(savedInstanceState);
Intent data = new Intent();
String text = "extSlabNo";
data.PutExtra("extSlabNo", text);
data.PutExtra("remWidth", 10);
data.PutExtra("remHeight", 20);
data.PutExtra("Position", position);
SetResult(Result.Ok, data);
}
Then you could modify the data in the adapter according to the positon value:
public void ActivityResult(int requestCode, Result resultCode, Intent data)
{
switch (requestCode)
{
case 1:
if (data != null)
{
try
{
string remSlab = data.GetStringExtra("extSlabNo");
int position = data.GetIntExtra("Position", -1);
if (remSlab != null && position >= 0)
{
RemnantList[position].Width = data.GetIntExtra("remWidth", -1);
RemnantList[position].Height = data.GetIntExtra("remHeight", -1);
NotifyDataSetChanged();
}
}
catch (Exception ex)
{
var method = System.Reflection.MethodBase.GetCurrentMethod();
var methodName = method.Name;
var className = method.ReflectedType.Name;
MainActivity.SaveLogReport(className, methodName, ex);
}
}
break;
}
And reset the adapter in MainActivity OnActivityResult() method :
public class MainActivity : AppCompatActivity
{
RemnantListAdapter remnantListAdapter;
ListView listView;
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
SetContentView(Resource.Layout.activity_main);
List<InventorySlabs> remnantList = new List<InventorySlabs>();
for(var i = 0; i < 10; i++)
{
InventorySlabs inventorySlabs = new InventorySlabs();
inventorySlabs.Depth = i.ToString();
inventorySlabs.ExtSlabNo = i.ToString();
inventorySlabs.Finish = "Finish" + i.ToString();
inventorySlabs.Height = 200;
inventorySlabs.SellName = "SellName" + i.ToString();
inventorySlabs.Status = "Status" + i.ToString();
inventorySlabs.Width = 400;
remnantList.Add(inventorySlabs);
}
listView = FindViewById<ListView>(Resource.Id.listView1);
remnantListAdapter = new RemnantListAdapter(this, remnantList);
listView.Adapter = remnantListAdapter;
}
protected override void OnActivityResult(int requestCode, [GeneratedEnum] Result resultCode, Intent data)
{
remnantListAdapter.ActivityResult(requestCode, resultCode, data);
listView.Adapter = remnantListAdapter;
}
}

I have two applications, sending messages asynchronously in both directions. I am using sockets of type ZMQ.DEALER on both sides. The connection status is additionally controlled by heartbeating.
I have now problems to get the connection reliably recovering after connection problems (line failure or application restart on one side). When I restart the applicaton on the server side (the side doing the bind()), the client side will not always reconnect successfully and then needs to be restarted, especially when the local buffer has reached the HWM limit.
I did not find any other way to make the connection recovery reliable, other than resetting the complete ZMQ.Context in case of heartbeat failures or if send() returned false. I will then call Context.term() and will create Context and Socket again. This seemed to work fine in my tests. But now I observed occasional and hangups inside Context.term(), which are rare and hard to reproduce. I know, that creating the Context should be done just once at application startup, but as said I found no other way to re-establish a broken connection.
I am using JeroMQ 0.3.4. The source of a test application is below, ~200 lines of code.
Any hints to solve this are very much appreciated.

I have a custom class as follows which works fine, the button grows/shrinks to accomodate the text and the bg image changes on a click.
Probem I want to solve is how to "fadeIN" one or other image when clicked/notClicked is called
Here is my code
public ExpandingOvalButton(String text) {
if (text.length() > 15) {
label.getElement().getStyle().setFontSize(20, Unit.PX);
} else {
label.getElement().getStyle().setFontSize(30, Unit.PX);
}
int width = 120;
initWidget(panel);
label.setText(text);
// width = width + (text.length() * 8);
String widthStr = width + "px";
image.setWidth(widthStr);
image.setHeight("100px");
button = new PushButton(image);
button.setWidth(widthStr);
button.setHeight("50px");
panel.add(button, 0, 0);
panel.add(label, 18, 14);
}
public void isClicked()
{
image.setUrl("images/rectangle_green.png");
}
public void unClicked()
{
image.setUrl("images/rectangle_blue.png");
}
#Override
public HandlerRegistration addClickHandler(ClickHandler handler) {
return addDomHandler(handler, ClickEvent.getType());
}
public void setButtonEnabled(boolean enabled) {
// panel.setVisible(enabled);
// this.label.setVisible(enabled);
this.button.setVisible(enabled);
}
Here's a general utility class to fade any element:
public class ElementFader {
private int stepCount;
public ElementFader() {
this.stepCount = 0;
}
private void incrementStep() {
stepCount++;
}
private int getStepCount() {
return stepCount;
}
public void fade(final Element element, final float startOpacity, final float endOpacity, int totalTimeMillis) {
final int numberOfSteps = 30;
int stepLengthMillis = totalTimeMillis / numberOfSteps;
stepCount = 0;
final float deltaOpacity = (float) (endOpacity - startOpacity) / numberOfSteps;
Timer timer = new Timer() {
#Override
public void run() {
float opacity = startOpacity + (getStepCount() * deltaOpacity);
DOM.setStyleAttribute(element, "opacity", Float.toString(opacity));
incrementStep();
if (getStepCount() == numberOfSteps) {
DOM.setStyleAttribute(element, "opacity", Float.toString(endOpacity));
this.cancel();
}
}
};
timer.scheduleRepeating(stepLengthMillis);
}
}
Calling code for instance:
new ElementFader().fade(image.getElement(), 0, 1, 1000); // one-second fade-in
new ElementFader().fade(image.getElement(), 1, 0, 1000); // one-second fade-out
You could use GwtQuery. It provides fadeIn & fadeOut effects (and many other JQuery goodies), it is cross-browser compatible and seems to be pretty active.
I'm a beginner in BlackBerry programming, I need to replace in my application the default menu (when you press the menu button) by a custom menu, horizontal. The best to describe is I want the same result as the WeatherEye application for BlackBerry...
alt text http://www.blackberrybing.com/resource/pics/201002/WeatherEye-OS-45.jpg
I know how to create the default menu, but this one I have no idea!
Thank you,
What you will need to do is:
create SizebleVFManager (contentManager) as an extension of VerticalFieldManager
set display width and height = (display height - menu height) size to contentManager
add contentManager to screen
create HorizontalFieldManager (menuManager)
create BitmapButtonField (menuButton) as an extension of ButtonField
set FieldChangeListeners to menuButtons
add menuButtons to menuManager
add menuManager to screen
Sample of SizebleVFManager :
class SizebleVFManager extends VerticalFieldManager
{
int mWidth = 0;
int mHeight = 0;
public SizebleVFM(int width, int height, long style) {
super(style);
mWidth = width;
mHeight = height;
}
public SizebleVFM(int width, int height) {
mWidth = width;
mHeight = height;
}
public int getPreferredWidth() {
return mWidth;
}
public int getPreferredHeight() {
return mHeight;
}
protected void sublayout(int width, int height) {
width = getPreferredWidth();
height = getPreferredHeight();
super.sublayout(width, height);
setExtent(width, height);
}
}
...
SizebleVFManager contentManager =
new SizebleVFManager(Display.getWidth(), Display.getHeight(),
VERTICAL_SCROLL|VERTICAL_SCROLLBAR);
See also
sample of BitmapButtonField and Toolbar
PS though its better to use standard menu...
UPDATE
If you want to disable default menu functionality, cancel MENU keydown:
protected boolean keyDown(int keycode, int time) {
if(Keypad.KEY_MENU == Keypad.key(keycode))
{
return true;
}
else
return super.keyDown(keycode, time);
}
UPDATE
I've installed that wonderful weather application and understood this sample may be more alike with several improvements:
use CyclicHFManager as an extension of HorizontalFieldManager
show/hide menuManager on Menu button click
CyclicHFManager is a manager which will keep focus on the same place visually and run all fields over, in cycle. Like in BlackBerry - Custom centered cyclic HorizontalFieldManager
class CyclicHFManager extends HorizontalFieldManager {
int mFocusedFieldIndex = 0;
boolean mCyclicTurnedOn = false;
public void focusChangeNotify(int arg0) {
super.focusChangeNotify(arg0);
if (mCyclicTurnedOn) {
int focusedFieldIndexNew = getFieldWithFocusIndex();
if (focusedFieldIndexNew != mFocusedFieldIndex) {
if (focusedFieldIndexNew - mFocusedFieldIndex > 0)
