I have a basic GUI (plain Jframe with a button) and I have changed the look and feel using Nimrod. The new l&f is a dark theme which I change at runtime.
However, when the GUI is run, for a very brief moment, the GUI has a bright background, and then the new dark l&f is then applied.
I assume what is causing this brief flash of brightness is that at runtime, the default l&f is showing briefly, just before the new one is being applied.
It’s only a fraction of a second, but it’s noticeable and quite annoying as it looks untidy.
It doesn’t seem to happen if I change the l&f after runtime with a button.
So, does anyone else have any experience with this? Is there a possible workaround for this? Hide the JFrame until the new l&f is applied?
Here’s my code if that helps:
public static void main(String[] args)
{
setTheme();
NewJFrame njf = new NewJFrame();
njf.setLocationRelativeTo(null);
njf.setTitle("My First Swing Application");
njf.pack();
njf.setVisible(true);
}
static void setTheme()
{
NimRODTheme nt = new NimRODTheme();
nt.setPrimary1( new Color(0,51,153));
nt.setPrimary2( new Color(0,92,143));
nt.setPrimary3( new Color(0,102,153));
nt.setSecondary1( new Color(31,31,31));
nt.setSecondary2( new Color(41,41,41));
nt.setSecondary3( new Color(51,51,51));
nt.setWhite( new Color(0,0,0));
nt.setBlack( new Color(255,255,255));
nt.setMenuOpacity(195);
nt.setFrameOpacity(180);
NimRODLookAndFeel NimRODLF = new NimRODLookAndFeel();
NimRODLF.setCurrentTheme (nt);
try
{
UIManager.setLookAndFeel(NimRODLF);
}
catch(Exception e)
{
}
}
Also, if nimrod is needed, you can get it here: http://www.mediafire.com/?l9pytbooenmemgc
Any help at all is greatly appreciated.
