How can I eliminate the lines in TreeView while keeping all arrows

只谈情不闲聊 提交于 2021-01-06 03:48:09
问题 I have a TreeView which I am skinning using the SetWindowsTheme() pinvoke, however I am unable to remove the tree lines that appear. I do not wish to do 'Owner' drawn as I believe that would be the equivalent of taking an 18-wheeler truck to deliver one taco (overkill). What is a clean, quick way to eliminate the Tree forks while keeping the expansion arrows. (I need to keep the arrows on the root nodes as well) should look like : 回答1: Try this: yourTreeView.ShowLines = false; yourTreeView

问题 I'm playing around with the d3 js tree layout. I was following this example. I was trying to add class attribute to each of the node. How can i add one class to the root node and a different class to children node. var treeData = [{ "name": "Top Level", "parent": "null", "children": [{ "name": "Level 2: A", "parent": "Top Level", "children": [{ "name": "Son of A", "parent": "Level 2: A" }, { "name": "Daughter of A", "parent": "Level 2: A" }] }, { "name": "Level 2: B", "parent": "Top Level" }]

JavaFX 2 TreeView Styling - lines from parents to children

落爺英雄遲暮 提交于 2020-12-30 02:22:45
问题 I have a pretty big structure of data, which I want to show in the TreeView. When a lot of branches and sub-branches are opened, it's not clear what belongs to what. Is there a way (CSS?) how to style the TreeView, so it will be showing the lines from parents to children like in Swing? Thank you for any ideas... 来源: https://stackoverflow.com/questions/33297616/javafx-2-treeview-styling-lines-from-parents-to-children

为什么 Linux 的 htop 命令完胜 top 命令

在 Linux 系统中,top 命令用来显示系统中正在运行的进程的实时状态,它显示了一些非常有用的信息,比如 CPU 利用情况、内存消耗情况,以及每个进程情况等。但是,你知道吗?还有另外一个命令行工具 'htop',它与传统的 top 命令功能一样,但它有更加强大的功能及能显示更多的信息。这篇文章,我们会用实例来讨论这个 'htop' 命令。 Linux 中的 htop 命令 下面是从 htop 的手册页摘抄下来的相关描述: 它类似于 top 命令,但可以让你在垂直和水平方向上滚动,所以你可以看到系统上运行的所有进程,以及他们完整的命令行。 可以不用输入进程的 PID 就可以对此进程进行相关的操作 (killing, renicing)。 首先明白它的输出 htop 命令以直观的格式来显示信息。下面是 HTOP 的输出快照: htop 如果你观察窗口的左上角部分,你会看到显示的是 CPU 负载、内存消耗及交换空间的实时信息,右上角包含的是任务、线程、平均负载及系统运行时间的信息。 平均负载部分提供了三个数字,这仅仅表示的是过去的5分钟、10分钟和15分钟系统的平均负载而已,在单核的系统中,平均负载为1表示的是百分之百的 CPU 利用率。最后,运行时间 (uptime)标示的数字是从系统启动起到当前的运行总时间。 下面,我们将用例子来进一步讨论这个命令。 1. 用 F2 键编辑配置
