Align with component in another panel
ok, I have two panels with a checkbox and a textfield in each. I want the respective checkboxes to be aligned and also the textfields with eachother.
another question is if I can set the background of a JTextArea if it doesn't have a name, I've just added it to a panel with
panel.add(new JTextArea("hello my friend");
greatful for advice
love/m
no, I can use any layout that helps me get the result I want!
right now, I've chosen another solution, but I still would like ideas on alignment since the new design includes four panels with different contents. I wants the four panels to have the same size (oh, they need to be in individual panels since they all have different borders) so I've used gridlayout. but now the component JTextField grows to an ugly size trying to fill the flippin' panel.
does this make sense? I hope you understand what I mean.
best regards/m

How to merge the Panel with another Panel to One Panel?
As Title!!
i will give it a shot. by no means do i say it is correct being a beginner myself
Panel aPanel = new Panel();
Panel anotherPanel = new Panel();
Panel mythirdPanel = new Panel();
aPanel.add(anotherPanel);
aPanel.add(myThirdPanel);
this should create one panel called aPanel with two panels inside - another Panel first, followed by mythirdPanel second. This should be in FlowLayout pattern as that is default unless specified.
That is my guess and my shot.

How to use another panels in status line
Hi Everyone:
Can anybody tell me how can i use another panels in the
Console's status line, I'm using the message line but i need to
show the user's name and Date-Tiem in another section of the
status line and not in display controls as i'm already doing it.
Thanks.Do you really need a JSF component for that? You can use h:panelGroup and some JS. But a simple div with some JS is also sufficient.

JPanel not repainting if embedded in another panel
I have a reusable class called as DuplicatorPanel. This class has two add/ remove buttons like in Mac if you are familiar.
The problem is that the screen gets updated with an extra row in case i have a main method in Duplicator itself. However if i have that in another panel as in HyperlinkBuilder then it does not repaint itself.
Please can someone help ?

Replace that repaint() with revalidate. That is the trick in there.

How will the change be reflected dynamically if the value changes in some other panel.By code that you write. If you want component X to change based on some changes to component Y, then first you set up a listener which will notify you when changes to component Y take place. In that listener you put code which makes the appropriate changes to component X, based on what happened to component Y. -
Replace a component by another in a Frame
Hi all!
I've a frame with several component (panels, buttons...) set with a gridbaglayout.
I would like to know if i could replace a component by another.
For instance.
Frame f = new Frame();
button b1 = new button("b1");
panel p = new panel()....
f.add(b1)
/* replace b1 by p
like :
f.remove(b1);
f.add(p);
*/Thanks!Sure, you can replace any component by enother one.
add f.validate() in the end. -
Form Guide - Populating a drop down with entries from another field(s)
Greetings all!
Here is what I am trying to accomplish:
1. Build a repeating panel that has a field for the entry of a Name. (I can do this)
2. Build a drop down field on another panel that will be populated with the Name entries from one or more of the repeating panel Name fields in 1. above. I would like this to happen while the user is in the same render of the form guide.
3. Setup:
LC ES2
Workbench 9.5
Would utilize Workspace to complete the form guide
Want to use a .fml data model
Any help would be appreciated.
Best Regards,
Rick Kuhlmannpguerett,
Many thanks for that lca. I have been able to move forward with development of a POC Form Guide.
However, I have one other issue that if solved will push my POC to the point of demo status for the business.
Here it is:
The business needs to be able to add the names of children to a Children Info panel on the form guide. - No problems with that.
Then they need to be able to go to another panel in the form guide and select a child name from a drop down to associate that child with the name of a father. - The previous post with the lca solved that.
Now what I need to do is to be able to take the selected child in the father panel and place that value into the data model.
Why? because the final part of this form guide is to populate a pdf form that is really a legal petition to the court. The child(ren) names form the Children Info panel are listed at the beginning of the petition. Then the selected child in the father panel is displayed in the father section.
So what I am looking to do is to populate that selected child in the father panel to a property in the data model.
However, based on the lca you sent it does not seem that when I add a Data Object to the Data Model in the Guide Builder that I am not able to push that data back into the original Data Model. I thought that using a Binding might work but I have struck out so far.
Clear as mud? Any help you or anyone else can provide would be wonderful.
Thanks a ton!

Displaying thumbnail images in another panel when it mouse clicked
hi,
I am using JAI, what i am trying to do is i am decoding the tiff file and creating thumbnail of that images and adding thumbnail images to one panel and enlarged images to another panel using DisplayJAI. Now when i will click i thumbnail images on left panel then that image should be display to another panel on right side. Adding both panel to JSplit panel.
I have no idia how to do it, i tried to do in different way but not able to do that. I hope anybody can give me the hints about this.
Thanksi am adding thumbnail of all images in left panel and enlarged view of each thumbnail is added in right panel , and what i require that when i click thumbnail in left side it's corresponding enlarged image should be visible, suppose in right panel page no. 1 is visible and when i click thumbnail of 13 page in left panel that should be in viewport of right panel.You should put your right panel inside a JScrollPane and call [scrollRectToVisible() |http://java.sun.com/javase/6/docs/api/javax/swing/JComponent.html#scrollRectToVisible(java.awt.Rectangle)] from your panel. You can put the rectangles corresponding to enlarged images in a hash map with the keys being some unique attribute of your thumbnails in left panel. That will help in getting the rectangle to make visible, real fast. Or, you can just put the rectangles in some array indexed according to the thumbnails in left panel.
I also want to hide the left panel, i think it's possible by Frame.Yes it is possible, but you said you have both your panels in a split pane, so maybe you can use its setDividerLocation() function to hide your left panel.
Thanks! -
How can I make numbers align with the baseline in ordered lists with inline images?
When I use inline images in an ordered list, the number for every line that has an inline image is offset from the baseline to align with the top of the image. Here is a screen shot from Preview mode (same behavior on real devices):
List entries 1 and 3 are normal. Entries 2 and 4, which contain inline images, have their numbers offset above the baseline.
I guess the line-height gets redefined based on the inline image, and then the numbers align based on line-height. Is there a way to change this within Muse so the numbers will consistently sit at the baseline even when the line includes an image? Is it something that needs to be addressed by modifying style sheets?Hi,
You are correct in observing that inline objects affect line height, which in turn affects alignment of the bullet/number with the line.
To address this, you can use negative wrap offsets on the inline (specifically top offset) using the Wrap panel: adjust the value until the inline no longer adversely affects line height.
Hope this helps.

I am working on a program and need to put one panel into another panel . I have been successful at adding the panel
however when i do this i cannot set the size of the 2nd panel. The first panel on the frame is just fine
i have tried adding the panel to the first panels constructor this works the panel shows up but i am unable
to set the size of the panel which is the problem.
I tried calling this.setSize in the second panels constructor to solve this problem no luck there
i have also tried adding the 2nd panel to the frame but this produces the same problem as stated above
im really stumped any help woul be appreciated

add(canvas, BorderLayout.CENTER);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(1000,1000);
setVisible(true);

d = new DiaDisplay(220,20,40,200);
s = new SysDisplay(420,220,40,200);
rep.start();

i have tried.. What happened to your shift key? Please apply it once at the start of every sentence, rather than those rare occasions you 'feel like it'. Adding an upper case letter to each sentence makes it easier for people to quickly scan the text, looking for ways to help. You would not want to make it harder for someone to help, would you?

Thanks for your help,
Mario.If I understand, you want to display a popup Titlewindow from

Simplify your code to get it working first.

Component visibility getting delay while drop the component in the Panel
Hi,
In my project I have used drag and drop functionality to drop the Icon from 1st panel to 2nd panel. The 1st panel contains three buttons with different icons and the 2nd panel is added as the destination (Drop place) in the desktop pane. While drag and drop I have used a panel and label to place the icon in the 2nd panel. The icon which is available in the label visibility getting delay(nearly 5 - 10 sec) at the first time drag and drop. After that there is no time delay for the drag and drop. This happens all the time while start my project. I have tried repaint() and revalidate() for all the panels still the delay is there. Kindly suggest any idea to reduce the delay.

Need help with component label
Hi all,
I want to have label for my components. so when any existing components on the page is opened for editing(for example if I open any components in edit mode from foundation, Tab name is seen and if there is multiple tab like in textImage component its confusing what component is that)I am using fieldLabel properties to show label in my component but this properties is not working for me. Please advice...
Thanks A lot in Advance..Hi,
Yeah, its clear now. sorry for confusion. So as i understood you actually want to show label for your component not the tabs and OOTB using title will not help you. If you want to achieve this then you have to change your hierarchy.
Yake an example:
If your current hierarchy is like below
dialog (tabpanel) --> items (widgetcollection) --> tab1 (panel)--> items (widgetcollection) --> etc.....
then you have to move your tabpanel inside another panel which has property "layout" and value as "fit", so the new hierarchy will look like this
dialog (panel) -->items (widgetcollection)-->Main Tab(tabpanel) --> items (widgetcollection) --> tab1 (panel)--> items (widgetcollection) --> etc.....
and at panel use property "title" to set the main title
The look and feel will be different than to normal tab panel obviously as you used panel but hope it will be fine.
Let me know you need more information.
I would also suggest you to refer - http://dev.day.com/docs/en/cq/current/widgets-api/output/CQ.Ext.TabPanel.html from more info.
Thanks,
Pawan
