How to drag and drop file between maximized windows in Awesome WM ?

Hello,
I am newbie to awesome WM. I am a web developer and usually need to edit files after downloading from FTP. I am using filezilla for FTP and sulblime text 2 for coding.
How can I drag file from filezilla and drop into sublime window for editing when both windows are maximized? Is it possible? Same way sometimes I also need to drag file from nautilus to filezilla for uploading to FTP server?
I would be thankful if somebody can guide me to make it possible.
Thanks.

I have a similar problem in FLuxbox.
I can not drag a file from Thunar to any aplication.
I can "half solve" this problem in this manner:
Drag a file from a ubication, press ALT + TAB to switch between programs and then drop it inside.
My problem is that Fluxbox not change from one window to another when you put a file over the taskbar. I do not know if Awesome WM can switch between applications using ALT + Tab but it is the idea.
Luck with it.
No awesome wm can't switch between applications when file is dragged using ALT + Tab or MOD4 + Tab and that's the problem.

Drag and Drop images between two listviews

I need a help for listview drag n drop opretion on winform. where listview1 hold the images and i want to drag images from listview1 to listview2
and then when i click any button i want all paths of Images which is in the listview2. and also i want to set the image size on listview2. Please help me.

Hi Ajay Kumar,
According to your description, you'd like to drag and drop listviewitems between two listviews.
Here is my example for dropping items between listviews. You could add one imageList control to your form.
public Form1()
InitializeComponent();
this.listView2.AllowDrop = true;
this.listView1.AllowDrop = true;
this.listView2.View = System.Windows.Forms.View.LargeIcon;
this.listView2.DragDrop += new System.Windows.Forms.DragEventHandler(this.OnDragDrop);
this.listView2.DragEnter += new System.Windows.Forms.DragEventHandler(this.OnDragEnter);
this.listView1.ItemDrag += new System.Windows.Forms.ItemDragEventHandler(this.OnItemDrag);
private void Form1_Load(object sender, EventArgs e)
DirectoryInfo dir = new DirectoryInfo(@"D:\Material\Emoticons");
foreach (FileInfo file in dir.GetFiles())
try
this.imageList1.Images.Add(Image.FromFile(file.FullName));
catch
Console.WriteLine("This is not an image file");
this.listView1.View = View.LargeIcon;
this.imageList1.ImageSize = new Size(32, 32);
this.listView1.LargeImageList = this.imageList1;
this.listView2.LargeImageList = this.imageList1;
//or
//this.listView1.View = View.SmallIcon;
//this.listView1.SmallImageList = this.imageList1;
for (int j = 0; j < this.imageList1.Images.Count; j++)
ListViewItem item = new ListViewItem();
item.ImageIndex = j;
this.listView1.Items.Add(item);
private void OnItemDrag(object sender, System.Windows.Forms.ItemDragEventArgs e)
DoDragDrop(e.Item, DragDropEffects.Move);
private void OnDragEnter(object sender,
System.Windows.Forms.DragEventArgs e)
if (!e.Data.GetDataPresent(typeof(ListViewItem)))
e.Effect = DragDropEffects.None;
return;
var items = (ListViewItem)e.Data.GetData(typeof(ListViewItem));
if (items == null)
e.Effect = DragDropEffects.None;
else
e.Effect = DragDropEffects.Move;
private void OnDragDrop(object sender, System.Windows.Forms.DragEventArgs e)
ListViewItem items = (ListViewItem)e.Data.GetData(typeof(ListViewItem));
if (items != null)
this.listView2.Items.Add((ListViewItem)items.Clone());

RE : Drag and Drop operations between two outlinefields

Hi,
Has any one tried the drag and drop operations between two Outline widgets ina
window.Any help appreciated.
Thanks
balsubHi Balsub,
Here are some lines which can help you :
First of all, your 2 OutLineFields must be in a draggable state.
In the event loop of your window, you have to listen to the event
ObjectDrop
on the 2 OutLineFields :
When Self.<MyOutLine1>.ObjectDrop(SourceX = SourceX,
SourceY = SourceY,
SourceField = SourceField,
TargetX = TargetX,
TargetY = TargetY,
TargetField = TargetField) do
When Self.<MyOutLine2>.ObjectDrop(SourceX = SourceX,
SourceY = SourceY,
SourceField = SourceField,
TargetX = TargetX,
TargetY = TargetY,
TargetField = TargetField) do
Then, when you receive this event, the LocateNode() method will give you
the DisplayNode which is beeing dragged :
(assume that your OutLineFields are mapped to the class named :
ClassOutLine,
and Col is an Integer which is not important here)
TheSourceLine : ClassOutLine;
Col : Integer;
TheSourceLine = (ClassOutLine)((OutLineField)(SourceField).LocateNode(X
= SourceX,
Y = SourceY,
Column = Col));
If you want to remove this line from the Source OutLineField :
TheSourceLine.Parent = Nil;
TheSourceLine.UpdateFieldFromData();
If you want to insert this line at the end of the Target OutLineField :
TheSourceLine.Parent = (OutLineField)(TargetField);
TheSourceLine.UpdateFieldFromData();
And if you want to insert this line before or after the Target line of
the Target OutLineField :
TheTargetLine : ClassOutLine;
TheTargetLine = (ClassOutLine)((OutLineField)(TargetField).LocateNode(X
= TargetX,
Y = TargetY,
Column = Col));
TheTargetLine.PrevSibling = TheSourceLine; // Insert the source line
before the target line
or
TheTargetLine.NextSibling = TheSourceLine; // Insert the source line
after the target line
TheTargetLine.UpdateFieldFromData();
I hope this help you !

There is no configuration for it. It should work.
Can you try it in a different user account. If it works in a different account, then it is likely something in your current user account that is messed up. If it doesn't work in another user account, then it is likely something with Mail, itself.
You could try downloading and installing the 10.6.7 combo update. That may repair what is wrong.

How to drag and drop files in Time Machine Capsule?

Hi, all
I have recently bought a Time Machine 2 TB. I have backed up my MacBook Air over the Time Machine. I was trying to copy or drag and drop files in the time capsule, but it wont allow me. It Neither does allow me to create any new folders in the Airport Time Machine. If i try to drag and drop files in it, it says, click to Authenticate, however, there is no place or tab to authenticate. I am the administrator.
Please advise.
Thanks

It sounds like you are trying to copy / paste files to the Time Capsule Finder icon, when you should be copying / pasting to the drive on the Time Capsule, which is named "Data" unless you have changed it.
Open any Finder window and look for the Time Capsule icon under the Shared heading on the left side of the window
Click on the Time Capsule, which will display a folder to the right named Data, unless you have changed the name of the drive
Double-cllick on Data to mount the drive on the desktop
You can drag / drop or copy / paste files onto the drive icon, or open the drive and drag files into the open window.
The first time that you do this, you may be asked for the Time Capsule device or disk password.

How do I drag and drop files between computers when using Home Sharing in ITunes?

How can I drag music files between computers while using Home Sharing? An older version of ITunes had a Home Sharing icon in the column browser near the playlist so it was easy to drag and drop.

Hello cacalenni,
Thanks for using the Apple Support Communities. I understand that you wish to learn how to import songs using Home Sharing in the new iTunes. The following resource should assist you in doing so:

I can't seem to drag and drop files between my hardrives?

They are both formatted MS-DOS (FAT), I can only drag and drop from the hardrives to the desktop not the other way around or between the two? Thanks

Thankyou, I go between a microsoft and mac and was told that this format would work for that, what format would you suggest?
This depends on what you mean, can you provide more detail when you say, "I go between a microsoft and mac"? Please be descriptive so I can't leave anything up to assumption.

How to Drag and Drop in between Stacks?

I have a folder with various stacks and single images that I would like to sort manually. It seems impossible to drag and drop an image in between two stacks. It always ends up stacked with one or the other. I am being very careful to be sure that neither stack shows a border around it or is lighter than the other. But it makes no difference. Even if I expand both stacks, I can't drop an image in between. I have to completely UNSTACK the images, drag and then RE-STACK. Am I missing something??(running LR 2.4 on OSX 10.5.8)

Yeah, it's a bit tricky, messing with stacks and drag-and-drop.
Try going the other way round: drag and drop your stack (by selecting all images of the stack) instead of your single image, sometimes it helps (depending on the situation). The Remove from Stack command also helps to extract a single image from a stack without breaking and re-stacking.

How to drag and drop image between Windows platform and VM

Thanks.

Hi Deer2000,
There are several things you need to do first. You need a Transferable that can provide the image data in a format that the application likes. You will not be able to drop a serialized ImageIcon onto a native app for example. Most won't accept a binary stream even if you declare it's MIME type (e.g. image/jpeg) either.
You need to know what the native "clipboard" formats are. For example on Win32, DIB (device independent bitmap) and BITMAP are clipboard image formats. Learn the format and write an InputStream the can provide it. Then add your stream to a FlavorMap.
What is a FlavorMap and why do I need one?
Most native apps don't understand MIME types for data transfer. They have their own "clipboard" types. Java DataFlavors are based on MIME types. In order to provide a mapping between the win32 format TEXT and MIME types text/plain;charset=ascii you create a FlavorMap. Actually the default system flavormap does this type for you.
An easy way to add mappings is to edit $JDKHOME/jre/lib/flavormap.properties. For our custom image stream we've added the following entry:
DIB=image/x-win-bmp;class=com.rockhoppertech.dnd.datatransfer.BitmapInputStream
Other Win32 clipboard formats are:
WAVE
RIFF
PALETTE
ENHMETAFILE
METAFILEPICT
DIB
TIFF
Or please refer this URL, which gives a good idea about drag and drop in Java

I hope this will help you.

Can't drag and drop files between spaces in lion osx

since upgrading to lion osx, i've noticed that i can't drag a pic, for example, from safari and drop it into a chat box in ichat. used to drag pics, web addresses, text, etc across spaces all the time in snow leopard but i don't seem to be able to do it in lion. does anyone else have this problem or am i missing something?

You have many issues with your and your wife's machine(s). Everything you've posted works here. Reinstall Snow Leopard, repair permissions, and see if that fixes things.

How to drag and drop tab nodes between tab panes

I'm working on example from this tutorial( Drag-and-Drop Feature in JavaFX Applications | JavaFX 2 Tutorials and Documentation ). Based on the tutorial I want to drag tabs between two tabs. So far I managed to create this code but I need some help in order to finish the code.
Source
tabPane = new TabPane();
Tab tabA = new Tab();
   Label tabALabel = new Label("Main Component");
tabPane.setOnDragDetected(new EventHandler<MouseEvent>()
            @Override
            public void handle(MouseEvent event)
                /* drag was detected, start drag-and-drop gesture*/
                System.out.println("onDragDetected");
                /* allow any transfer mode */
                Dragboard db = tabPane.startDragAndDrop(TransferMode.ANY);
                /* put a string on dragboard */
                ClipboardContent content = new ClipboardContent();
                content.put(DataFormat.PLAIN_TEXT, tabPane);
                db.setContent(content);
                event.consume();
What is the proper way to insert the content of the tab as object? Into the tutorial simple text is transferred. How I must modify this line content.put(DataFormat.PLAIN_TEXT, tabPane);?
And what is the proper way to insert the tab after I drag the tab:
Destination
tabPane.setOnDragDropped(new EventHandler<DragEvent>()
            @Override
            public void handle(DragEvent event)
                /* data dropped */
                /* if there is a string data on dragboard, read it and use it */
                Dragboard db = event.getDragboard();
                boolean success = false;
                if (db.hasString())
                    //tabPane.setText(db.getString());
                    Tab tabC = new Tab();
                    tabPane.getTabs().add(tabC);
                    success = true;
                /* let the source know whether the string was successfully
                 * transferred and used */
                event.setDropCompleted(success);
                event.consume();
I suppose that this transfer can be accomplished?
Ref javafx 2 - How to drag and drop tab nodes between tab panes - Stack Overflow

I would use a graphic (instead of text) for the Tabs and call setOnDragDetected on that graphic. That way you know which tab is being dragged. There's no nice way to put the Tab itself into the dragboard as it's not serializable (see https://javafx-jira.kenai.com/browse/RT-29082), so you probably just want to store the tab currently being dragged in a property.
Here's a quick example; it just adds the tab to the end of the current tabs in the dropped pane. If you wanted to insert it into the nearest location to the actual drop you could probably iterate through the tabs and figure the coordinates of each tab's graphic, or something.
