2 things.

  1. How do I get the alias of the image someone drops in?

  2. How do I set the image using resources?

I tried image() and setImage_() but I can’t do anything but set the default in IB.

Hi,

1.) You have to implement the drag&drop event handlers

2.) create an NSImage with initWithContentsOfFile:, the file path can be specified with the method pathForResource:ofType: of NSBundle

#3

Deal with 2 first.

valwiniconpic's setImage_(pathForResource_ofType_("AlertStopIcon","icns"))

gets:

2009-09-30 15:24:25.523 Dialog Maker[408:a0f] *** -[Dialog_MakerAppDelegate pathForResource:ofType:]: unrecognized selector sent to object <Dialog_MakerAppDelegate @0x2002dc060: OSAID(4)>
2009-09-30 15:24:25.530 Dialog Maker[408:a0f] *** -[Dialog_MakerAppDelegate subiconpic:]: *** -[Dialog_MakerAppDelegate pathForResource:ofType:]: unrecognized selector sent to object <Dialog_MakerAppDelegate @0x2002dc060: OSAID(4)> (error -10000)

#4

pathForResource returns a string path, but setImage expects an NSImage

Take a look at this thread

#5

PS: You can’t initialize a NSImage directly with an .icns file using initWithContentsOfFile:, but there is a work around

NSImage *iconImage = [[NSWorkspace sharedWorkspace] iconForFile:@"/path/to/file.icns"];
#6 
log "3"
set newImage to NSImage's alloc()'s initWithContentsOfFile_(pathForResource_ofType_("AlertStopIcon", "icns"))
log "3.1"
valwiniconpic's setImage_(newImage)
log "3.2"

It logs this error:

#7

If the image is in the bindle, you can also do it this way:

		tell class "NSImage" of current application to set thePic to imageNamed_("Chart.icns")
		imageWell's setImage_(thePic)
#8

How come that works and the other one didn’t? Oh well it’s working brilliantly, thanks. I need a way now to set the well with an icon file from anywhere in the system (with value returned from

choose file of type {"com.apple.icns"}

) , I’m guessing your method won’t work.

#9

The problem was in pathToResource_ofType_ – you were trying to use a class method without reference to the NSBundle class.

Like this:

set posPath to POSIX path of (choose file)
		set newImage to NSImage's alloc()'s initWithContentsOfFile_(posPath)
		imageWell's setImage_(newImage)

Thanks, but just as I saw the panel post I changed my mind (sorry XD :lol:)

How can I put a Finder window inside one of those ‘panels’? I looked at browser view but I’m not sure about it all.

:slight_smile:

#11

What do you mean by a “Finder window”?

#12

Like save panels that come down like in TextEdit.

#13

There are classes like NSOpenPanel and NSSavePanel, which include everything

#14

OK how do I go about that then?

#15

OK I have put in a choose file instead, but now all I need to implement it is the way to get the file location from the well’s image, whether my app chose the image or it was dragged in.

#16

The image doesn’t record the location of the original; you’ll need to store it yourself when you create the image.

#17

I already have IBActions for dragging and choosing, by me writing ‘choosing’ just there I remembered something, so now getting the icon on choose file is sorted so now what I need to know is how to get the alias of an image dragged in.

:slight_smile:

#18

Bump. Please reply to my recent question about drag and drop.

#19

You’re going to have to override the drag-and-drop code so you can catch the path. Not exactly straight forward.

#20

This post shows how to accomplish this.

Make sure to read the documentation for registerForDraggedTypes since those have
changed in 10.6.
