How to set padding between columns of a JavaFX GridPane?
提问by Click Upvote
I'm trying to show a 2-column grid in a javaFx program. This is how I'm setting up the grid:
我正在尝试在 javaFx 程序中显示一个 2 列网格。这就是我设置网格的方式：
GridPane grid = new GridPane();
ColumnConstraints column1 = new ColumnConstraints();
column1.setPercentWidth(50);
ColumnConstraints column2 = new ColumnConstraints();
column2.setPercentWidth(50);
grid.getColumnConstraints().addAll(column1, column2);
Here's the problem. I want to show a small space between where one column ends, and the other starts. However, the columns are showing up as glued to one another.
这就是问题所在。我想在一列结束的地方和另一列的开始之间显示一个小空间。但是，这些列显示为彼此粘合。
Here's a screenshot:
这是一个屏幕截图：
Here each column contains the 'item name' and 'process, edit, delete' buttons.
这里的每一列都包含“项目名称”和“处理、编辑、删除”按钮。
You can see how the columns are glued together. I want them to instead have some space between them.
您可以看到列是如何粘合在一起的。我希望它们之间有一些空间。
How can I solve this?

For better appearance you can use a mix of:
为了获得更好的外观，您可以混合使用：
grid.setHgap(10); //horizontal gap in pixels => that's what you are asking for
grid.setVgap(10); //vertical gap in pixels
grid.setPadding(new Insets(10, 10, 10, 10)); //margins around the whole grid
//(top/right/bottom/left)

In addition to assylias's answer, you can configure the margin for any given node within the grid:
除了 assylias 的答案，您还可以为网格中的任何给定节点配置边距：
GridPane.setMargin(node, new Insets(5, 10, 5, 10));
GridPane.setMarginjavadoc:
GridPane.setMarginjavadoc：
Sets the margin for the child when contained by a gridpane. If set, the gridpane will lay it out with the margin space around it. Setting the value to null will remove the constraint.
当被网格窗格包含时，设置子项的边距。如果设置，gridpane 将用它周围的边距空间进行布局。将该值设置为 null 将删除约束。
Eventually (post Java 8), JavaFX may allow you to set a margin around any node, not just those in a GridPane.
最终（Java 8 之后），JavaFX 可能允许您在任何节点周围设置边距，而不仅仅是 GridPane 中的那些。
