Patrick, I just noticed tonight that horizontal scrolling is not working in the "Fields" spreadsheet view in the CSV/Text Import window in Calc (the part that shows you a preview of what your data will look like as you change the separators, etc.
10.5.2/Intel/trackpad

It does not appear to me that mouse scrolling is supported in those fields by the OOo code. Note that I have not changed the OOo code with this feature. Instead, I merely post horizontal mouse wheel events to the OOo event queue. Most OOo controls will react to it, but some most likely will ignore scrolling events.

Fun  
Thanks for checking.

Testing test-5, I had 3 instances (out of around 25) of a vertical mouse action interloping when I was scrolling right with my trackpad, and that seems to depend on positioning of the fingers on the trackpad itself - implying that it really does seem to matter that I'm left-handed!
If the right fingertip is below the left in terms of y-value on the trackpad, it's more likely to trigger a vertical down-scroll whilst right horizontal scrolling. It would appear that the inbuilt intelligence for the trackpad allows for diagonal scrolling, and is more likely to trigger this is the fingertips are placed diagonally with respect to each other and the trackpad gesture is not completely horizontal.

Your logic is correct: dialogonal scrolling is allowed and supported by NeoOffice.
With the scrollpad or a mouse trackball, NeoOffice will get both mouse scroll events with both X and Y coordinate changes and our code will respond to both.

Just curious, I am a Java developer, how did you do this? |

We modified native Cocoa code. Specifically, we subclassed the Cocoa NSWindow class' sendEvent: selector and to manually post custom mouse wheel events to the Java event queue.
Since NeoOffice loads Java in process using C code, we can install custom Cocoa subclasses before Java is loaded. However, I am not so sure that this would work as reliably if done using JNI after Java has been loaded.

Hi,
I was just implementing the new multitouch features of the current MB pro/ MB Air in one of my programs as I ran across this thread.
It's pretty simple, if You can grab the NSEvents - and once You start using them, You don't want to miss'em. Guestures are a little like magic .
I think magnifiy for zoom an swipe for pageup/pagedown would be cool.
Here two obj-c code snippets for inspiration:
for a NSView:
| Code: |
- (void)magnifyWithEvent:(id)fp8
{
//[fp8 deltaZ]
}
- (void)swipeWithEvent:(id)fp8
{
//[fp8 deltaX] => horizontal swipe (+/- 1.0)
//[fp8 deltaY] => vertical swipe (+/- 1.0)
}
- (void)rotateWithEvent:(id)fp8
{
//[fp8 rotation]
}
|
or if you grab it at the root (i.e. subclassing NSApp's sendEvent):
| Code: |
- (void) sendEvent:(NSEvent *)anEvent
{
switch ([anEvent type]) {
case 18: //rotate
//[anEvent rotation]
break;
case 30: //magnify
//[anEvent deltaZ]
break;
case 31: //swipe
//[anEvent deltaX] => horizontal swipe (+/- 1.0)
//[anEvent deltaY] => vertical swipe (+/- 1.0)
break;
default:
[super sendEvent:anEvent];
}
}
