Rush,
I tried this but unfortunately it doesn't seem to be getting called. As
I said, my custom-rolled event loop is a little odd and I think it's
swallowing events somewhere. Here's what I'm seeing:
1.) I click on my download link.
2.) I get several calls to decidePolicyForNavigationAction:
4.) I get a call to decidePolicyForMIMEType:
5.) If webview can't display it, I tell it to ignore it and handle the
download manually.
5.) My WebView freezes. I no longer get any events. I can close the
window and move it around and that works fine...so it would seem my
event loop is still processing events. Is WebKit doing something strange
with the view when a download is encountered? Where should I be
intercepting the download so I can handle it myself?
Thanks for your help!
Josh

Hi Josh,
I don't know about the second one, but I have dealt with file selection
from within my WebView. You need to implement the WebUIDelegate method
- (void)webView:(WebView *)sender
runOpenPanelForFileButtonWithResultListener:(id<WebOpenPanelResultListen
er>)resultListener
Here's mine, for what it's worth:
- (void)webView:(WebView *)sender
runOpenPanelForFileButtonWithResultListener:(id<WebOpenPanelResultListen
er>)resultListener
{
NSOpenPanel *panel = [NSOpenPanel openPanel];
int i = [panel runModalForDirectory:NSHomeDirectory()
file:nil
types:nil];
if (i == NSOKButton)
{
[resultListener chooseFilename:[[panel filenames]
objectAtIndex:0]];
}
}
Remember to register as the delegate by sending
[myWebView setUIDelegate:self]
in your window controller.
