How to make a frame modal?

Hei guyz,
I'm trying to call a frame from another frame (which should basically act like a dialog, but is not a dialog), how can i make this 'child' frame modal, i.e. once im done with the 'child' frame, the focus has to go back to the 'parent' frame and no other component could be opened while a user is working on the 'child' frame.
Can anyone let me know, how this is possible and is there any other better approach (other than making the child frame, a dialog)?
Thanks in advance.

and is there any other better approach How can we suggest a better approach when we don't know why you rejected a modal dialog.
Based on your requirement:
once im done with the 'child' frame, the focus has to go back to the 'parent' frame and no other component could be opened while a user is working on the 'child' frame.
it would appear to me that using an modal dialog is the obvious choice.
Otherwise I suggest you search the forum. Keywords like "modal jframe" would be a good place to start.

How to make a frame with components and JTextAreas on it?

on the Window 98 System, when you press F1 on the keyboard, you will get a window(frame) where there are "buttons" and "textAreas".
i would like to create a JFrame like that, but how to realize it?
thanks a lot!!!

What do you want to do?
You can easily create a JFrame, and then create JButtons and JTextAreas and then add() them to the JFrame's content pane.
But you must know that already, so it must be something different you are confused about. What is it?

To give focus to an internal frame, do the following (where iFrame is your internal frame):try {
    iFrame.setIcon( false ); // In case it is minimized
    iFrame.moveToFront();     // Make sure it is in front
    iFrame.requestFocus();    // Ask for focus
    iFrame.setSelected( true ); // Select it
} catch( java.beans.PropertyVetoException pve ) {
}

How to make homemade frames?

How do you go about making a frame such as the one in this example:
http://photoma.my-expressions.com/index.html
Thanks in advance.

Jack,
I originally posted this in another forum, but here it is again,
how to create a 3D frame.
http://www.pixentral.com/show.php?picture=13RZnH4exD8TdEkmW2Vs3p8ZLi9y1m0
1. Set Background color to default white (see Note at end).
2. Image>Resize>Canvas Size, and increase Height and Width by the same amount. This creates a white frame.
3. Using the Magic Wand tool with the Contiguous box checked, select the frame.
4. Set Foreground color to your frame color.
5. Add new layer.
6. Edit>Fill, using Foreground Color option.
7. Window>Layer Styles. Choose the Bevels style.
8. Choose one of the styles. In my example I used Simple Sharp Inner.
9. To modify the bevel effect, click on the "f" symbol in the Layer's palette (truncated in my example), or from the menu bar Layer>Layer Style>Style Settings. This brings up the Style Settings dialog box where you can adjust various settings. You can also modify the frame via Layers>Layer Style>Scale Effect.
If you want the frame inside the picture (not expanding the canvas):
1. Use the Rectangular Marquee tool to draw out the frame.
2. Invert the selection.
3. Proceed with step 4. above.
Note 1: In step 1, I chose white because my picture didn't have any white touching the frame. You can use any color; the goal is that when you do the Magic Wand it doesn't select anything within the picture. That's also why you check the Contiguous box.

How to use single frame in a page

Hello, i would like to now how to make a frame in a page
without having two or more, i was used to work with GoLive and
there i could use the grid an put a single frame and make links to
other pages that would open in that frame, it worked wel for me,
but since I switched from golive to dreamweaver CS3 i am not able
to do so. Is there some one how could tel me how to do so, since i
use a lot of single frames in my pages,
greetings

why are you wanting to use single frames?
They allow having the initial frame address stay in the
address bar, and not
show the linked page's address. The problems they cause
usually override any
value.
Or- if we aren't using the same words the same way, please
give an example
site of what you want to do.

How to decrease photo frame width in photoshop?

hi guys
i have a small question to ask to the experts....i want to decrease the width of a wooden frame psd file to suit my design "the frame is so thick"
simply scaling it down wont do the trick beacuase i will have only small version of it and i want to keep it general size "apart from its width obviously"
in other words how to make the frame "thinner" but keep the size of it?
thank you all in advance

Well, here's one possibility:
1. Duplicate the document as several different documents.
2. Stretch one of them in the vertical dimension only, and the other in the horizontal dimension only.
3. Use the Rectangular Marquee tool to copy the longer, thinner sections independently and paste them in another image.
Or you could generate a new frame... There's a great(!) set of free framing actions out there made by a great guy named Bud Guinn online. My internet connection is acting up today, and I couldn't complete a Google search for some reason, but look for "Bud Guinn framing action".
Here's one link that shows them off...

How to make a modal frame?

Hello!
My problem is quite simple, but I don't know how to make some MODAL frames (JFrame I mean). In my application, the user can open a same frame even if this frame is already opened and that's not really good.
So, I want the user to close the frame before opening another one.
Can anyone explain me how to do that?

Generally your actionListener will be an internal class of your main frame class. Usually an anonymous internal class. That means it can act on variables in the frame (which is the sensible place to keep the flags).
Something like:
class Class1 extends JDesktop {
boolean itsOpen = false;
openAction.setActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {
    if(!itsOpen) {
       itsOpen = true;
       openAction.setEnabled(false);
       MyInternalFrame newFrame = new MyInternalFrame(Class1.this, ....);
       add(newFrame);
   });You do need some way for the internal frame to act on the variables in the main frame. There are various ways of achieving this.
If we're dealing with a genuine InternalFrame there's a special InternalFrameListener (?) which allows your main frame to listen for the window closing. You can use this instead of hacking the dispose method.
If you're main frame is a JDeskTop then you can use getDesktop() in your internal frame to access it, then cast the result to the real class of your desktop.
Our you can simply add a pointer to your class1 to the contructor of your internal frame class.
You could even get clever and create your own listener system.
