Adding and removing components from a container in Java
I would like to have class extending JLabel or JPanel added to my frame. To this panel or label I would like to add 6 JLabels, when created. I would also like to have a button wich would remove all the 6 Labels from the ancestor label or panel.
I am facing problem with both adding and removing. Upon addition and removal, the 6 components don't behave as they should. When I try to add them (they have built-in MouseListener which change their background when entered) they do not appear untill I enter them with my mouse. When I I am trying to remove them (by method .remove or .removeAll()) they stay as they were.
I used methods
public void render() {
for(int i = 0 ; i < 6 ; i++) {
particularLabel[i].setBounds(0, 50*i, 280, 50);
this.add(particularLabel[i]);
}
}
and
public void renderEmpty() {
for(int i = 0 ; i < 6 ; i++) {
this.removeAll();
}
}
Is there a way to make these labels visible in my program? And is there a way to successfully get rid of them?

1) For better help sooner, post a Minimal, Complete, and Verifiable example or Short, Self Contained, Correct Example. 2) Java GUIs have to work on different OS', screen size, screen resolution etc. using different PLAFs in different locales. As such, they are not conducive to pixel perfect layout. Instead use layout managers, or combinations of them along with layout padding and borders for white space.

1) For better help sooner, post a Minimal, Complete, and Verifiable example or Short, Self Contained, Correct Example. 2) Java GUIs have to work on different OS', screen size, screen resolution etc. using different PLAFs in different locales. As such, they are not conducive to pixel perfect layout. Instead use layout managers, or combinations of them along with layout padding and borders for white space.
