javascript – 卡布奇诺 – CPSplitView固定子视图的大小

2023年2月4日 197次阅读

我有一个继承自CPSplitView的GridNode类,用于包装GridELement类型的对象. GridNode的每个连续拆分将其划分为两个新的GridNode(包含使用其父级调整大小的GridElements).

另一个类 – GridToolbar继承自GridElement.它应该基本上与GridElement具有相同的行为,尽管大小不应自动更改(因为容器已调整大小),但仅在用户拖动拆分器之后.

问题是,即使我将AutoresizingMask设置为特定方向(因为工具栏可以是垂直或水平),它仍然会在它们中调整大小.

有什么建议我可以采取哪些措施来防止这种情况发生？

GridNode.j的来源：

@implementation GridNode : CPSplitView
{
}

- (id)initWithFrame:(CGRect)aFrame
{
  self = [super initWithFrame:aFrame];

  if(self)
  {
    [self setAutoresizingMask:CPViewWidthSizable | CPViewHeightSizable ];
    [self setBackgroundColor:[CPColor colorWithHexString:"EEEEEE"]]
  }

  return self;
}

- (void)split:(id)sender
{
  var parent = [sender superview];

  var gridNode = [
    [GridNode alloc]
    initWithFrame:CGRectMake(
      0, 0,
      CGRectGetWidth([parent bounds]),
      CGRectGetHeight([parent bounds])
    )
  ];
  [gridNode setVertical:(CGRectGetWidth([gridNode bounds]) >= CGRectGetHeight([gridNode bounds]) ? YES : NO)]

  var element = [
    [GridElement alloc]
    initWithFrame:CGRectMake(
      0, 0,
      CGRectGetWidth([parent bounds]),
      CGRectGetHeight([parent bounds])
    )
  ];

  [self replaceSubview:parent with:gridNode];

  [parent setBtnTarget:gridNode];
  [element setBtnTarget:gridNode];

  [gridNode addSubview:parent];
  [gridNode addSubview:element];
}

- (void)addBar:(id)sender
{
  var parent = [sender superview];

  var gridNode = [
    [GridNode alloc]
    initWithFrame:CGRectMake(
      0, 0,
      CGRectGetWidth([parent bounds]),
      CGRectGetHeight([parent bounds])
    )
  ];
  [gridNode setVertical:(CGRectGetWidth([gridNode bounds]) >= CGRectGetHeight([gridNode bounds]) ? YES : NO)]

  var isVertical = [gridNode isVertical];
  var toolbar = [
    [GridToolbar alloc]
    initWithFrame:CGRectMake(
      0, 0,
      CGRectGetWidth([parent bounds]),
      CGRectGetHeight([parent bounds])
    )
    vertical: isVertical
  ];

  [parent setBounds:CGRectMake(
    isVertical ? 32 : 0, isVertical ? 0 : 32,
    CGRectGetWidth([gridNode bounds]) - (isVertical ? 32 : 0),
    CGRectGetHeight([parent bounds]) - (isVertical ? 0 : 32)
  )];

  [self replaceSubview:parent with:gridNode];

  [parent setBtnTarget:gridNode];
  [toolbar setBtnTarget:gridNode];

  [gridNode addSubview:toolbar];
  [gridNode addSubview:parent];
}

@end

GridElement.j的来源：

@implementation GridElement : CPView
{
  CPButton btnSPlit;
  CPButton btnToolbar;
}

- (id)initWithFrame:(CGRect)aFrame
{
  self = [super initWithFrame:aFrame]

  if (self)
  {
    [self setAutoresizingMask:CPViewWidthSizable | CPViewHeightSizable ];
    [self setBackgroundColor:[CPColor colorWithCalibratedRed:Math.random() green:Math.random() blue:Math.random() alpha:1.0]];

    btnSPlit = [
        [CPButton alloc]
        initWithFrame:CGRectMake(0,0,128,24)
    ];

    [btnSPlit setAutoresizingMask:CPViewMinXMargin | CPViewMaxXMargin | CPViewMinYMargin | CPViewMaxYMargin];
    [btnSPlit setFrameOrigin:CGPointMake((CGRectGetWidth([self bounds]) - CGRectGetWidth([btnSPlit frame])) / 2.0,
                        (CGRectGetHeight([self bounds]) - CGRectGetHeight([btnSPlit frame])) / 2.0 - 15)];
    [btnSPlit setTitle:"split me!"];

    [btnSPlit setAction:@selector(split:)];

    [self addSubview:btnSPlit]

    btnToolbar = [
        [CPButton alloc]
        initWithFrame:CGRectMake(0,0,128,24)
    ];

    [btnToolbar setAutoresizingMask:CPViewMinXMargin | CPViewMaxXMargin | CPViewMinYMargin | CPViewMaxYMargin];
    [btnToolbar setFrameOrigin:CGPointMake((CGRectGetWidth([self bounds]) - CGRectGetWidth([btnToolbar frame])) / 2.0,
                        (CGRectGetHeight([self bounds]) - CGRectGetHeight([btnToolbar frame])) / 2.0 + 15)];
    [btnToolbar setTitle:"split me!"];

    [btnToolbar setAction:@selector(addBar:)];

    [self addSubview:btnToolbar]
  }

  return self;
}

- (void)setBtnTarget:(id)aTarget
{
  [btnSPlit setTarget:aTarget];
  [btnSPlit setTitle:"split "+aTarget._UID]
  [btnToolbar setTarget:aTarget];
  [btnToolbar setTitle:"toolbar "+aTarget._UID]
}

@end

GridToolbar.j的来源：

@implementation GridToolbar : GridElement
{
  CPButtonBar btnBar;
}

- (id)initWithFrame:(CGRect)aFrame vertical:(BOOL)isVertical
{
  self = [super initWithFrame:CGRectMake(
    0,0,
    isVertical == NO ? aFrame.size.width : 32,
    isVertical == YES ? aFrame.size.height : 32
  )]

  if(self)
  {
    isVertical == YES ? [self setAutoresizingMask:CPViewWidthSizable] : [self setAutoresizingMask:CPViewHeightSizable];
    [self setBackgroundColor:[CPColor blackColor]];

    btnBar = [
      [CPButtonBar alloc]
      initWithFrame:CGRectMake(
        0,0,
        CGRectGetWidth([self bounds]),
        CGRectGetHeight([self bounds])
      )
    ];
  }

  return self;
}

@end

最佳答案 我收到了一个有用的建议
here.创建我自己的委托,在拖动分隔符时根据固定值集自动调整GridNode子视图的大小是我必须做的.
