drag&drop from outside dows not mark target

pila · Post by **pila** » 2003 Sep 04, 15:48

When i try to drag&drop something from e.g. desktop to x2 folder pane, it does not show in bold the target active folder.

It reacts well otherwise, it will open subfolders, but wil not show what is current target.

surely the target folder is hilighted though (?)
the bold item doesn't really mean much other than the last folder that had the focus

No, nothing is highlited. That is my problem. Only the last used folder is bolded.

Let's compare the experiences:

1. As soon as I make a new selection, the previously visited folder loses active focus (blue highlighting): only a dotted line is shown around it (you can turn that into proper "focus" by pressing the SpaceBar.)

2. I select some files/folders and then drag them to a folder which is in the opposite pane (or sometimes even the same pane). When I hover the mouse pointer over the target folder, it always highlights it (makes it dark blue).

This happens even in case of the target being a zip folder.

I use details view with single-click activation; with Win NT4/2k.

Essentally nothing new in what is described here, but what's the difference in your settings/observations/OS?

Post by **nikos** » 2003 Sep 09, 09:44

perhaps we have a terminology issue here
what i (&narayan) mean by "hilighted" is a change in the background color that indicates either selected or drop target states.

pila, what do you mean by "bolding"? Are you referring to the single item in the tree that is printed in bold font? Then see my earlier response

if you don't get targets hilighted (in my use of the word) then the objects you are trying to drag will not be accepted by the item/folder under the mouse cursor

P.S. Another thing you can try is watch the dbmon output while you are dragging over the various folders. If the folder is receptive it will say so in the debug output window

narayan · Post by **narayan** » 2003 Sep 09, 12:07

it will open subfolders, but will not show what is current target.

Probably you are trying to drop your selection in the tree? Because a drag-n-drop won't open subfolders when you hover mouse in folfder pane; but the tree would.

But even there the x2 shows the target folder in dark blue.

BTW Nikos, I found another problem while trying pila's problem: if you hover the selection over a removable drive (in the tree), x2 pops up an error message "Drive is not accessible: the device is not ready" and freezes. The mouse pointerturns into hourglass.

I have to terminate x2 using Windows Task Manager.

Here's the log:

i tried hovering over an empty floppy label and sure enough the error box came up, but after hitting ESC it went away and the drag was aborted. So no freezing for me.

BTW pila, these are the lines in the dbmon output you should be looking for when targeting folders in the tree (i was talking about them earlier):

156: InShellDragLoop = 1
156: TREE: drop target = 'D:\temp'
156: TREE: drop target = 'D:\Temp for zip'

Nikos, I have tried what narayan has quoted and hovered a file over the a:\ drive and got x2 to freeze. Here is the debug report. It will not let me press Escape to clear the error, and I have to go through the task manager to shut down x2.

serves you right for using a backwards OS like NT4

i think narayan is using the same, here's the common clue
i tried on w2000

what if you use the keyboard (arrows+enter key) to dismiss the error dialog without releasing the mouse? It's a bit of hand-juggling but I'm just curious!

anyway i think i know how to stop these dialogs popping up, will do for the next build

vserghi · Post by **vserghi** » 2003 Sep 10, 08:22

Hey don't blame me about the OS, blame my company. As it happens I was one of the last to be given a PC with WinNT. Were all gradually moving over to Win2k. Anyway isn't Win2K/WinXP based on the NT kernel? So does that make Win2k backward also?

Your method works fine. I can cancel the request and x2 continues as normal.

Post by **nikos** » 2003 Sep 10, 10:05

after a little bit of struggle i can report that the issue is fixed even for NT4!
now i'm going back to the find command internals

pila · Post by **pila** » 2003 Sep 10, 11:19

1. I open x2. Active folder is in blue square and bold
2. I drag an icon from the desktop over the x2 folders pane. BLue square dissapears from the active folder in the folders pane, it remains only Bold.
3. Moving dragged icon over the folders at the fodlers pane, I have no indication where it will be moved if I drop it.

I use Win2k and x2 v42

narayan · Post by **narayan** » 2003 Sep 10, 12:24

There are two differences from what you describe:

1. When I make a selection, blue highlight goes from the previously visited folder (this part is same as what you observed). But the difference is that there is no Bolding. In fact, I can't see any "bolding" in frolder panes at all. (I can see it in tree, but the bold node is NOT the current node in the active pane. Is this a bug??)

I may not be able to see bold letters because of my selection of small fonts- I don't know.

2. When I move the selection to any destination folder (including zips), the corresponding folder gets blue highlight (as Nikos and I described earlier).

In my case, x2 behaves identically in Win NT4 and 2k.

Post by **nikos** » 2003 Sep 10, 12:31

pila, please see the dbmon output while you are dragging over the tree as explained further up. Do you see any messages indicating that the tree is reacting either negative or positive?

another thing you can try: does this happen no matter what you drag or only for some items?

(i take it that the hilight problem doesn't occur when you drag items from within x2 and not from the desktop ?)

vserghi · Post by **vserghi** » 2003 Sep 10, 12:42

Could he be describing the fact that the tree does not follow the active pane. If I change folders within a pane, the tree will remain on its last active drive. If Alt+T is pressed the tree will highlight and make bold the curent folder in the active pane.

If he does indeed drag a file from the desktop (or folder) to a folder in the tree, the folder in which the file was copied is not highlighted. If a mistake was made, such as a slip of the finger on the mouse, then the location of the file is lost unless a search is performed.

Am I correct in this pila?
