REg : DateExComboBox - Color Issue & Min Date and Max Date

[dineshddk]

Hi Team,

1. I am using the "Date Ex Combo Box" sample. I'm unable set the Foreground and Background Color for Combo box "down arrow button". Please refer the attached screenshot.


2. I attached the sample program extending the "Date Ex Combo Box" class.
If I set the "Minimum Date" & "Maximum Date" for the Date Model but it fails to set Max and Min Limit. (But the arrow buttons are still Enable to select behind / beyond the date).


FYI: If the class is not extended, the date limits are working fine.

But I'm unable to set the user defined color for the date 1-31, week column and other colors as extended in user defined class.

Could you please suggest is there any method to set the user defined color for the date and down arrow buttons, minimum / maximum date. ?

1, Please delegate the getDateModel() to DateChooserPanel so that the DateChooserPanel could know the min/max date setting in the DateModel. The modified class is attached FYI.
2, Please create the button by overriding DateExComboBox#createButtonComponent() so that you could get full control of the foreground/background of the button. The modified code is also included in the attached classes FYI.

Thanks,

Hello,

Also, I have an issue about ExCombobox's background. I need to set background for ListExCombobox, TreeExCombobox, MonthExCombobox, ...

Could you please help me? I've tried combobox.setBackground(Color.x); however, it doesn't work.

Thank you!

Code: Select all

        ExComboBox comboBox = ...
        comboBox.setEditable(true);


You can set the editorComponent color. However I believe Windows uses native code to draw the text field so you can't set the background. Foreground works but not background.

Code: Select all

        fontComboBox.getEditor().getEditorComponent().setForeground(Color.GREEN);
        fontComboBox.getEditor().getEditorComponent().setBackground(Color.RED);

Thank you for your concern. I tried and as you said I can just be able to change foreground color. Instead of this solution, I tried to set UI. I can change the color of combos. However, this time when I clicked them, "Exception in thread "AWT-EventQueue-0" java.lang.NegativeArraySizeException" exception appears.

What did you do exactly? The complete code?

I was trying to change UI. Finally, I solved the problem. Colors are changed, also panels are working well.
The code was like this;

"UIDefaults defaults = UIManager.getDefaults();
defaults.put("ExComboBoxUI", "com.jidesoft.plaf.basic.BasicExComboBoxUI");"

Thank you for your support! Best regards.
