Hi all,

I'm using DOM parser for parsing the xml file in my code and I have been developed a UI such a way that if user edits the data that should rewrite to the xml file.Here,I'm able to write the all the contents back to the xml file but the schema I have written is mentioned statically in my code.

How can i read the xml schema from xml so that the schema i can rewrite to xml after editing the text in UI.Any suggestions please.

Hi all,

I have developed swing based java application. I have overwritten most of the paintComponent methods for customizing look and feel.

I have 3 xml files, First file consists of background colors(like 123,123,123), foreground colors of various components and other files consists of some data.So, when i load the application first those 3 files must be parsed and loads the application as per the colors in the first xml file.

My issue is while running the application it takes more time as expected to display the UI.Can anyone suggest to improve the performance of UI.

Thanks,

I have a class which extends JFrame. The frame must not be resized when the frame reaches to the particular dimension(say for eg: If the size of my screen is 1440x900 then my frame when minimizing if it reaches to 1200x800 it must not be resized).
I have to write frame listeners or i have to implement paint method of the panel in the frame.

Hi everyone,

My requirement is, based on the screen size(resolution)components should be aligned properly.Presently I have used GridBagLayout manager to arrange components wherever i need in the frame.But when i minimized or maximized the components are not aligned properly.

so,i want to get resolution of the screen(frame size) at runtime.based on the resolution i can arrange components correctly.

can anyone give me suggestions for this.
