我正在尝试创建一个类似reeder/sparrow的ui来处理我的应用程序的内容。目前我使用一个NSPLISTVIEW,里面有两个NSVIEW(左边的是内容列表,右边的是“检查器”)。
我想知道的是如何在标题栏上创建分隔符,它也可以作为分割视图的分隔符。
我已经在使用INAppStoreWindow子类了。
有什么想法吗?提前付款
最佳答案
我这样做的方法是添加一个nssplitview子类作为inappstorewindow的tilebarview的子视图:
// This code comes from the INAppStoreWindow readme
INAppStoreWindow *appStoreWindow = (INAppStoreWindow *)[self window];
// self.titleView is a an IBOutlet to an NSView that has been configured in IB with everything you want in the title bar
self.windowTitleBarView.frame = appStoreWindow.titleBarView.bounds;
self.windowTitleBarView.autoresizingMask = NSViewWidthSizable | NSViewHeightSizable;
[appStoreWindow.titleBarView addSubview:self.windowTitleBarView];
这两个棘手的部分是使这个拆分视图的行为类似于标题栏(即仍然允许您拖动窗口),并将标题栏中的拆分视图与窗口中的主拆分视图同步,因此对用户来说它们看起来是相同的。
要解决第一个问题,您需要做的不仅仅是在标题栏nssplitview子类中从
-mouseDownCanMovewWindow
返回yes。若您这样做,则平铺栏的任何子视图都不会响应鼠标事件。相反,请执行以下操作:@implementation MyTitleBarSplitView
- (BOOL)mouseDownCanMoveWindow
{
return NO;
}
// Code below adapted from http://www.cocoabuilder.com/archive/cocoa/219261-conditional-mousedowncanmovewindow-for-nsview.html
- (void)mouseDown:(NSEvent*)theEvent
{
NSWindow *window = [self window];
NSPoint mouseLocation = [theEvent locationInWindow];
NSRect dividerRect = NSMakeRect(NSMaxX([[[self subviews] objectAtIndex:0] frame]),
NSMinY([self bounds]),
[self dividerThickness],
NSHeight([self bounds]));
dividerRect = NSInsetRect(dividerRect, -2, 0);
NSPoint mouseLocationInMyCoords = [self convertPoint:mouseLocation fromView:nil];
if (![self mouse:mouseLocationInMyCoords inRect:dividerRect])
{
mouseLocation = [window convertBaseToScreen:mouseLocation];
NSPoint origin = [window frame].origin;
// Now we loop handling mouse events until we get a mouse up event.
while ((theEvent = [NSApp nextEventMatchingMask:NSLeftMouseDownMask|NSLeftMouseDraggedMask|NSLeftMouseUpMask untilDate:[NSDate distantFuture] inMode:NSEventTrackingRunLoopMode dequeue:YES])&&([theEvent type]!=NSLeftMouseUp))
{
@autoreleasepool
{
NSPoint currentLocation = [window convertBaseToScreen:[theEvent locationInWindow]];
origin.x += currentLocation.x-mouseLocation.x;
origin.y += currentLocation.y-mouseLocation.y;
// Move the window by the mouse displacement since the last event.
[window setFrameOrigin:origin];
mouseLocation = currentLocation;
}
}
[self mouseUp:theEvent];
return;
}
[super mouseDown:theEvent];
}
@end
业务的第二个顺序是同步这两个分离视图。使您的控制器类(可能是窗口控制器,但代码中有意义的部分)成为主内容拆分视图和标题栏拆分视图的委托。然后,实现以下两种nssplitview委托方法:
@implementation MyController
{
BOOL updatingLinkedSplitview;
}
- (CGFloat)splitView:(NSSplitView *)splitView constrainSplitPosition:(CGFloat)proposedPosition ofSubviewAt:(NSInteger)dividerIndex
{
// If already updating a split view, return early to avoid infinite loop and stack overflow
if (updatingLinkedSplitview) return proposedPosition;
if (splitView == self.mainSplitView)
{
// Main splitview is being resized, so manually resize the title bar split view
updatingLinkedSplitview = YES;
[self.titleBarSplitView setPosition:proposedPosition ofDividerAtIndex:dividerIndex];
updatingLinkedSplitview = NO;
}
else if (splitView == self.titleBarSplitView)
{
// Title bar splitview is being resized, so manually resize the main split view
updatingLinkedSplitview = YES;
[self.mainSplitView setPosition:proposedPosition ofDividerAtIndex:dividerIndex];
updatingLinkedSplitview = NO;
}
return proposedPosition;
}
- (void)splitView:(NSSplitView *)splitView resizeSubviewsWithOldSize:(NSSize)oldSize
{
// This is to synchronize the splitter positions when the window is first loaded
if (splitView == self.titleBarSplitView)
{
NSRect leftFrame = NSMakeRect(NSMinX([self.leftTitleBarView frame]),
NSMinY([self.leftTitleBarView frame]),
NSWidth([self.leftMainSplitView frame]),
NSHeight([self.leftTitleBarView frame]));
NSRect rightFrame = NSMakeRect(NSMaxX(leftFrame) + [splitView dividerThickness],
NSMinY([self.rightTitleBarView frame]),
NSWidth([self.rightMainSplitView frame]),
NSHeight([self.rightTitleBarView frame]));
[self.leftTitleBarView setFrame:leftFrame];
[self.rightTitleBarView setFrame:rightFrame];
}
}
