Hi all,
I¹m very confused.... I¹ve hunted through the Apple lists and Googled, and
I can¹t seem to find a way to save the split view divider positions when my
app quits, and then restore them when I re-launch.
I have three dividers, creating four panes in a window. One vertical
divider divides the right and left sections, and then each one of those
sections has a horizontal divider creating a top and bottom section. There
are scroll/table views in each of the four panes.
I tried every permutation of "bounds" and "size" by script -- I can save &
set the position of the vertical divider this way, but only after it is done
exactly four times... Mirroring what another poster described here, it
looks rather odd. However, I can't seem to set the position of the
horizontal dividers at all that way.
I followed the advice of this post:
http://lists.apple.com/archives/applescript-studio/2002/Nov/msg00116.html
...and created the appropriate files. First I tested this with the left
horizontal divider -- it worked! But a subsequent identical call method for
the right horizontal divider failed...?
So what to do with the vertical divider, as this post was for horizontal
only? I went to this post:
http://lists.apple.com/archives/applescript-studio/2002/Nov/msg00146.html
...and tried to create the method as indicated, with a "vertical" boolean
that would indicate to the function which type of divider was being passed.
No love.
Here are my Cocoa-illerate attempts to apply the advice of the 2nd post:

@implementation NSApplication (ASKAsplit)
/*Split view saving and restoring*/
- (NSString *) splitViewPosition: (NSSplitView *) splitView vertical: (BOOL)
vertical
{
NSArray *subViews = [splitView subviews];
int lenFirst, lenSecond;
if (vertical) {
lenFirst = [[subViews objectAtIndex: 0] frame].size.width;
lenSecond = [[subViews objectAtIndex: 1] frame].size.width;
} /*if*/
else {
lenFirst = [[subViews objectAtIndex: 0] frame].size.height;
lenSecond = [[subViews objectAtIndex: 1] frame].size.height;
} /*else*/
return [NSString stringWithFormat: @"%i %i", lenFirst, lenSecond];
}
- (void) setSplitViewPosition: (NSSplitView *) splitView position: (NSString
*) s
{
NSArray *subViews = [splitView subviews];
NSRect newBounds;
float dividerWidth = [splitView dividerThickness];
NSView *viewZero = [subViews objectAtIndex: 0];
NSView *viewOne = [subViews objectAtIndex: 1];
NSArray *stringComponents = [s componentsSeparatedByString: @" "];
int valueZero, valueOne;
valueZero = [[stringComponents objectAtIndex: 0] intValue]; valueOne =
[[stringComponents objectAtIndex: 1] intValue];
int topSize = valueZero;
int bottomSize = valueOne;
if ((topSize + bottomSize + dividerWidth) != [splitView frame].size.height)
topSize = [splitView frame].size.height - dividerWidth - bottomSize;
newBounds = [viewZero frame];
newBounds.size.height = topSize; // leftSize for vertical divider
newBounds.origin.y = 0;
[viewZero setFrame: newBounds];
newBounds = [viewOne frame];
newBounds.size.height = bottomSize; // rightSize for vertical divider
newBounds.origin.y = topSize + dividerWidth; // leftSize for vertical
[viewOne setFrame: newBounds];
}
@end
==================================================
But when I try to call the method to save the position:
set splitHorizLeftString to call method "splitViewPosition:" with parameters
{theLeftView, false}
I get nothing.
Can anyone please help me see where I'm going wrong?
Thanks,
Graham Jones.
