The issue described involves unexpected behaviour of a Java application's graphical user interface (GUI) when the window is resized. Resize the window causes the behaviour of certain JButton components to change, including the text and colour of the button.
To understand the problem, it's essential to examine the code and identify any dependencies between the window's size and the behaviour of the JButton components. The problem may lie in the way the components are laid out or in the way their properties are managed.
The provided code uses a ComponentAdapter to detect changes in the size of the DrawingArea component. When the size changes, the following actions are triggered:
These actions are undoubtedly intended to ensure that the timer starts when the window is resized. However, the code does not handle the resizing of other components, such as the JButton components.
The unexpected behaviour is likely caused by the way the JButton components are laid out and how their properties are managed. When the window is resized, the layout manager may be rearranging the components, which could affect their properties. For example, the text on the buttons may be truncated or the colours may change.
To address the issue, consider the following suggestions:
Here's an example implementation that uses a GridBagLayout to manage the layout and ensures that the JButton components retain their desired properties:
