I'm trying to write a kanban board. But if there are two and more stickers in one column, often the JToolBar with buttons will be shown only if you click on a sticker in this column for the firs time. I thought that there were some problems with coordinates, but I didn't found it. The StickerListener responds th event, even prints "условие работает" if coordinates are correct, but the JToolBar remainds invisible.

The problem is in the control flow of the StickerListener.mouseClicked(): you search the stickers to find the one that has been clicked.
Due to the if / else you reset the toolbar for every sticker that has not been clicked, meaning that your code only works if you clicked on the last sticker (in order of iteration).
Your code will work if you move the code from the else part before the loop (so that it executes only once):
