Configuration frame pop out of the main frame - how to do (architecture) ?
Hi,
I have a main frame that upon it I have a config button I did.
This button pop open another frame in which the user config some variables which I need to use in the main frame actions.
What is the right way to do it? -
1. in the main frame constructor to create a config frame and save it as a data member in the main frame with setVisibility false, and when the user press the 'config' button I'll change the visibility to true
(and then if I want to take data from the config frame I'll take it from there)
2. To save only the config data in data members (this is a small window - 3 or 4 variables) and every time the 'config' button is pressed I'll build a config frame and in its' constructor I'll send the variables I saved in the main frame
and they will be shown in there (and ofcourse when the config frame will be closed I'll save the new variables in the data members and dispose the config frame)
Thanks,
Michael
I have a little problem.
I build my own class that extends JDialog (with check boxes, text areas etc.)
Then I Created a JOptionPane with OK_CANCEL buttons set it as my dialog content pane.
Now I see the the pane buttons at the top and all my components at the buttom, and its now good.
So Instead of JDialog i extends my class to JPanel and then called
'JOptionPane.showOptionDialog' , and set my panel as the message.
Now it looks good but i have another problem -
I want to do a validity check before the dialog is being closed.
Before I did with 'addPropertyChangeListener' method on my JOptionPane, but now I dont have an OptionPane because the 'showOptionDialog' is static.
So for conclusion -
How can I build a dialog thats:
1. Look like I want (text areas, check boxes, lables ...)
2. Has OK\Cancel button
3. Lets me do validity check after the ok was pressed (and if I want - wont close the dialog)
4. Return me values from the dialog (the text in the text area, the selection of the check box etc.)

Drag JTabbedPane out of the main Frame and set scroll bars for the tabs
hi ,
Iam working on a Swing application . In it i have Six Tabs added to a single JTabbedPane. all the tabs are different class files . is it possible to drag any of the tabs out of the frame.
how to add scroll bars for the tabs individually. i have tried adding JScrollPane to the main frame and add the JTabbedPane to the Scrollpane . the scroll bar was not visible and i have tried adding
all the six tabs to the individual JScrollPanes and add the six scrollpanes to the TabbedPane .
only the scroll arrows are visible , when i minimised or resized the application the scrollbars were not appearing .
could any one help me to solve the above two problems.just trying.....
public void mouseDragged(MouseMotionEvent e){
// this event should be activated only when the Drag goes out of scope of the parent JFrame which i dont know how
Component c=JTab.getComponentAt(JTab.getSelectedIndex());

When i open apps sometime its pop out to the main page
hi...sometimes when i open an apps its just pop right out. lately i open my camera apps just about to took a photo its pop out again??...i wan to know can it be fix??
Try a reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.
If the Mail app still doesn't work after the iPad has restarted then try closing the app completely and see if it works when you re-open it : from the home screen (i.e. not with Mail 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of the Mail app to close it, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar. -
basically it's been a problem for a while now my sennheiser headphones are not clicking in correctly and are popping out at every movement causing it to pause my music, (very annoying) but it works fine if i hold it in, but can't do this all the time.I dom't know what the problem is or how i can fix.
any help would be greatly recieved
regards

Mini 210 screen is popped out from the cover.
As the subject indicates, I noticed a clicking noise when I closed the netbook. When I opened the netbook, I discovered that the clicking is coming from the screen popping out of the botton of the cover - just below the HP logo. It does not seem to causing any performance issues, but I was wondering if anyone else has the same issue.
Thanks,
DaveI have had the same thing happened to my HP Pavillion Dv2000
I think my warranty has expired but is there anyway to get HP to cover this? When I put the screen at certain angles the separation between the screen and the plastic covering is almost half an inch apart. I feel like it is going to snap at some point. Ridiculous. -
my iphone 5c screen is popping out from the top right side , can i exchange it for a new one at the apple store ?
If it is still under warranty, and they determine it is a manufacturing defect, they will replace it. Be sure to back everything up before taking it into the Apple Store. That way, if you do get a new device, you will be able to set it up from the backup.

Install Mavericks, Lion/Mountain Lion Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.
This will install the version of OS X that originally came with your model if you have a model that supports Internet Recovery - 2010 models and later: Computers that can be upgraded to use OS X Internet Recovery. -

Generally all you need do is give tracks from the same album a common Album Artist. See Grouping tracks into albums. The images need an update but the basic info. still holds.
