In my applet, whenever the user clicks some buttons it will open a new frame with differet titles. Now, I want to know how to keep track of these frames i.e. how to check what are all the frames that my applet opened. I don't want to store these objects in a hastable or so. Please suggest me how to do it. Thanks in advance. Regards, Jayakumar -------------------------------------------- Let me explain my problem. In my applet I am having three list boxes. After selecting one item from each lists and click the button, I am opening a new frame ( class is "DetailsFrame" which extends from java.awt.Frame )which gives some detail information about that combination. Suppose one is selecting item 1, item 2 and item 3 from the respective lists and clicks the button and a frame will be opened showing some info and with title with a combination of these values (say item1_item2_item3). Now what I want to do is, even when the button is clicked for the same combination i.e. item 1, item 2 and item 3 respectively, I should not open a new frame, but give focus to the frame which I already opened for the same combination. Right now I am solving this problem by storing the frame object in a Hashtable with the key as item1_item2_item3.
And just now I got some idea, that I can use Class.forName("DetailsFrame"); getClasses() which will return the array of instances of the classes and I can check for the title (i.e. item1_item2_item3), to get a correct object. Which way will be better i.e. storing in hastable or using getClasses() method? Thanks in advance. Regards, Jayakumar [This message has been edited by Jayakumar Gopalan (edited February 16, 2001).]
Jayakumar, Can you access the references to your frames in your Applet? i.e. are you saying something like :
or are you not able to get a reference to your frame since it is created as a local variable ( i.e. inside a method ). If you can access the reference of the Frame look at the isVisible() or isShowing() methods in the Component class (which Frame inherits from) they return booleans and I believe they would do what you need. If you cannot access the references of the Frames, I don't know what you could do... HTH, -Nate
