NSColorPanel阻塞鼠标向上事件 [英] NSColorPanel blocking mouse up events

问题描述

我使用的NSColorWell设置为不断更新。我需要知道用户何时完成从颜色面板中的颜色选择器编辑控件（鼠标向上）。

I am using a NSColorWell which is set to continuously update. I need to know when the user is done editing the control (mouse up) from the color picker in the color panel.

我安装了一个事件监视器，并成功接收鼠标移动和鼠标移动的消息，但是NSColorPanel似乎阻止了鼠标。

I installed an event monitor and am successfully receiving mouse down and mouse moved messages, however NSColorPanel appears to block mouse up.

底线是，我想将最终选择的颜色添加到我的撤消堆栈，而不会在用户选择他们的选择时生成所有中间颜色。

The bottom line is that I want to add the final selected color to my undo stack without all the intermediate colors generated while the user is choosing their selection.

是否有一种方法来创建自定义NSColorPanel并替换共享面板的想法覆盖其mouseUp和发送消息？

Is there a way of creating a custom NSColorPanel and replacing the shared panel with the thought of overriding its mouseUp and sending a message?

在我的研究中，这个问题

In my research this issue has been broached on a few occasions, however I have not read a successful resolution.

推荐答案

在界面生成器中，选择您的颜色，然后取消选中属性检查器中的连续复选框。另外，在 applicationDidFinishLaunching：方法或 awakeFromNib 方法中适当地添加以下代码行：

In the Interface Builder, select your color well, and then uncheck the Continuous checkbox in the Attributes Inspector. Additionally, add the following line of code somewhere appropriate like in the applicationDidFinishLaunching: method or awakeFromNib method:

[[NSColorPanel sharedColorPanel] setContinuous:NO];

换句话说，共享颜色面板和颜色需要连续设置为 NO ，以便正常工作。

In other words, both the shared color panel and your color well need to have continuous set to NO in order for this to work properly.
