在“仅文本”中单击时,NSToolbarItem (setView) 中的 NSButton强制模式为“图标和标签”
我正在尝试重新创建工具栏中的 Finder、Safari 和 Transmission 等漂亮的纹理按钮。首先,我首先在 IB 等中拖入“纹理按钮”。除非用户将工具栏设置为“仅文本”模式,否则一切正常。然后,当他单击该按钮时,工具栏将自行启用“图标和标签”。我已从工具栏中删除了所有代码和委托,以确保这不是代码问题。
然后,为了确保这一点,我创建了一个新项目(根本没有代码),我可以使用一个带有 NSToolbar 的干净 NSWindow 和一个带有 NSButton 的 NSToolbarItem 来重现该问题。
通过如下代码添加 NSButton:
- (NSArray*)toolbarAllowedItemIdentifiers:(NSToolbar*)toolbar {
return [NSArray arrayWithObject:@"myToolbarMenu"];
}
- (NSArray*)toolbarDefaultItemIdentifiers:(NSToolbar*)toolbar {
return [self toolbarAllowedItemIdentifiers:toolbar];
}
- (NSToolbarItem*)toolbar:(NSToolbar*)toolbar
itemForItemIdentifier:(NSString*)str
willBeInsertedIntoToolbar:(BOOL)flag
{
if ([str isEqualToString:@"myToolbarItem"] == YES) {
NSToolbarItem* item = [[NSToolbarItem alloc] initWithItemIdentifier:str];
[item setView:[[NSButton alloc] init]];
[item setMinSize:NSMakeSize(50,50)];
[item setMaxSize:NSMakeSize(50,50)];
[item setLabel:@"Text"];
return [item autorelease];
}
return nil;
}
但这也具有相同的效果:当我在“仅文本模式”下按下带有 NSButton 的 NSToolbarItem 时,工具栏本身会强制其模式为“图标和文本”。
您是否知道我如何才能使其正常工作,或者是否有其他方法来创建 Safari 等漂亮的工具栏项目?
I am trying to recreate the nice textured buttons like Finder, Safari and Transmission have in their toolbar. First I started by just dragging in a "Texture button" in the IB and such. All works well except for when a user sets the toolbar to "Text only" mode. When he then clicks the button the toolbar will enable "Icon and Label" on it's own. I have remove alles code and delegates from the toolbar to make sure it is not a code issue.
Then, just to make sure, I created a new project (no code at all) and I can reproduce the issue with a clean NSWindow with a NSToolbar with one NSToolbarItem with a NSButton in it.
Adding the NSButtons via code like:
- (NSArray*)toolbarAllowedItemIdentifiers:(NSToolbar*)toolbar {
return [NSArray arrayWithObject:@"myToolbarMenu"];
}
- (NSArray*)toolbarDefaultItemIdentifiers:(NSToolbar*)toolbar {
return [self toolbarAllowedItemIdentifiers:toolbar];
}
- (NSToolbarItem*)toolbar:(NSToolbar*)toolbar
itemForItemIdentifier:(NSString*)str
willBeInsertedIntoToolbar:(BOOL)flag
{
if ([str isEqualToString:@"myToolbarItem"] == YES) {
NSToolbarItem* item = [[NSToolbarItem alloc] initWithItemIdentifier:str];
[item setView:[[NSButton alloc] init]];
[item setMinSize:NSMakeSize(50,50)];
[item setMaxSize:NSMakeSize(50,50)];
[item setLabel:@"Text"];
return [item autorelease];
}
return nil;
}
But this also has the same effect: when I press a NSToolbarItem with a NSButton in it in "Text only mode" the toolbar itself forces it's mode to "Icon and Text".
Do you have any idea how I can make it work correctly or perhaps have an alternative to creating the nice looking toolbaritems like Safari etc have?

您需要向每个具有自定义视图的 NSToolbarItem 添加菜单表示。在分配 NSToolbarItem 的行下方添加以下内容:
只要目标有效,您的项目就应保留为纯文本按钮;否则他们将被禁用。请参阅 设置工具栏项目的表示。
通常,您还需要在目标中实现 validateToolbarItem: ,但对于自定义视图项,您需要重写 validate: 来执行适当的操作。请参阅 验证工具栏项目。
You need to add a menu representation to each NSToolbarItem that has a custom view. Below the line where you allocate the NSToolbarItem add this:
As long as the target is valid your items should stay as text-only buttons; otherwise they will be disabled. See Setting a Toolbar Item's Representation.
Normally you would also need to implement validateToolbarItem: in your target, but for custom view items you instead need to override validate: to do something appropriate. See Validating Toolbar Items.
