WrapLayout | 自动换行布局，水平排列子项，并自动换行，支持不等长不等宽子项，且可以设置垂直间距与水平间距及子项对齐模式。

I use WrapLayout which extends FlowLayout

Now, I have this GUI:

What I want is this:

I tried some things like: label.setVerticalAlignment(JLabel.TOP); but the layout does not seem to respect it. I guess this behavior is inherited from FlowLayout?

Full code:

I have 3 adjacent JPanels that each use WrapLayout to display a variable number of 1x16 grids.

It works great for the panel which contains the most 1x16 grids, however, the other two panels' dimensions seem to be determined by the panel that contains the most 1x16 grids. If, for example, panels 1 and 2 have only one 1x16 grid respectively, but panel 3 has ten 1x16 grids spread across two rows, then panel 1 and 2 both have a 1x16 grid-sized empty space beneath their respective 1x16 grids.

I basically want to get each panel's resizing to operate independently of the other panels. I've looked through camickr's src code for WrapLayout and can't quite work out what I should change to get the desired result.

In terms of code, it's tricky to know how to include a succinct and instructive section, as the code is quite spread out and I'm not sure what part is causing this issue. I'm just setting the panels' layout as a left-justified WrapLayout.

I've included an image below which might provide some context. The image shows part of two of the three JPanels (coloured cyan) and the accompanying title JLabel for one of those JPanels (coloured green). The 1x16 grids on each panel are managed using camickr's WrapLayout. All three cyan JPanels are contained within a larger display JPanel that has then been packed into a JScrollPane (hence the grey scroller to the right of the image).

Any help would be really appreciated.

Here's another image I created that shows the issue a little more clearly. The third panel in the image wraps to a new row to display all the 1x16 grids that it contains, and in so doing, doubles the height of the other two panels, despite them not needing to resize.

Here's how I want the GUI to display:

In my Nativescript Vue application changed from tns-core-modules to @nativescript/core and now I'm facing some issues. I created a Modal Service similar to this video. There I used the import :

I builds a mobile application which shows a vertical column of items when in each line there are 2 items. for this i use WrapLayout to break line after every two items. The problem is that when i have only single item left i want it to be on the right side of the column, but the default is the left. How can i change that?

I'm using JPanel with a default FlowLayout layout manager. I think in case the application window was resized and there is not enough width to show all components in JPanel in one row, some components will be moved to another row(s).

This assumption is based on the documentation:

If the horizontal space in the container is too small to put all the components in one row, the FlowLayout class uses multiple rows.

It works in some cases. For example, while using this code and decreasing window width, buttons will be located on different rows:
