Layout of a Panel

I am having trouble in specifying the layout of my panels. I essentially want a JTree to occupy the left 40% of the panel, and a JTextArea for the right 60%. Using BorderLayout.WEST for the alignment of the JTree, I find the area is too small. Using a GridBagLayout doesn't really produce results, even if I specify the left side to occupy a gridwidth of 2, and the rest to occupy a gridwidth of 3. Does anyone know of any way of setting the proportions? Or even better, can I put some kind of separator bar between the two areas, which is adjustable?
Thanks in advance...

Ok, if you use a GridBagLayout, there exist an interesting thing to deal with : the weights of each cells.
You can set each cell to have a horizontal (weightx) or vertical (weighty) weight.
For ur example, u should specify :
gridBagConst.weightx = 0.4;
gridBagLayout.setConstraints(jtree,gridBagConst);
// then add ur jtree
gridBagConst.weightx = 0.6;
gridBagLayout.setConstraints(jtext,gridBagConst);
// then add ur jtextOtherwise play with setMaximumSize(),setMinimumSize() and setPreferredSize().

Can we add more than one layout in a panel

hai everybody,
i m working in a project in that a panel(with gridbaglayout) does not allow borderlayout to set in the same panel..............
if we set so then components that is placed as in borderlayout is invisible
Help me out
Thanx in advance
shanthy

You cannot have more than one layout manager set on a container. This wouldn't make sense!
I'm guessing that what you're trying to do is have a panel with a BorderLayout with another panel with GridBagLayout in its centre.
Hope this helps.

Control layout of "Sliding Panels"?

Is there a way to control the layout of the sliding panels slide show theme? I have quite a few photos I'd like to display in a rather short length of time. It is also challenging because the photos are stills I captured from some prior iMovie/iDVDs so the resolution just isn't there. Therefore I'm trying to keep the layouts with the smaller pictures: 3, 4, 5 panels at a time (which look much better) and remove the layout for the single picture, double picture which exposes the poor resolution and doesn't let me get as many pictures fit into the time I need.

Thanks Terence, but I didn't ask about the timing of slides. I wanted to know if there is some way to adjust the layout so it only uses the smaller, multi-photo display in the Sliding Panels style. I'm not seeing anything in iPhoto itself, but I'm currently looking at a copy I made of the SlidingPanels.mrbStyle in the root Library > Application Support > iLifeSlideshow > Styles. In the bundle there is a StyleDescription.plist. And I notice there are 15 effect presets. The preset IDs are labeled pretty clearly. I'm thinking maybe if I delete some of the effect presets and rename the style maybe I'll get just the layout elements I need. I guess it is worth a shot unless anyone here knows of some way within iPhoto to select which layouts are used?

Change UI layout based on panel size

I am looking for a way to adjust the layout of my UI based on the panel's size. For example, two buttons that are above each other until the window height gets small enough that they need to be next to each other instead.
Another example would be a series of buttons that are displayed as a row if the panel is wider than it is tall, or as a column if it is taller than it is wide.
Anyone done anything like this, or know if it is possible? As I see it, all I need is a way to read the panel's current size and I can put a function into onResize/onResizing that adjusts the UI layout.

Figured it out!
This changes my row of buttons from a column to row based on the window ratio. Finally figured out windowBounds.height and windowBounds.width.
myPanel.onResizing = myPanel.onResize = function () {
if (myPanel.windowBounds.height > myPanel.windowBounds.width){
myPanel.grp.cmds.orientation = "column";
} else {
myPanel.grp.cmds.orientation = "row";
this.layout.resize();

Keyboard layout switcher Gnome panel

Hi guys,
Am using US altgr-intl as default.
The icon US keyboard pops up everytime I start the system though I removed the layout a couple of times through system->prefs.
It's not a big deal but starts to irritate me.
Anyone an idea how to either disable the popup of the panel icon or remove the US layout permanently ?
Tks

Thanks, did so, like this. Didn't help though.

<merge key="input.xkb.model" type="string">keyboard</merge>

CS6 Fluid Grid Layouts - opening CSSTransitions panel crashes program

Hi there, I'm on my second web page and this old problem has come up again.
I've asked about this before but I'm afraid I never got to the end of it, I just worked around it.
After I open the transitions panel, I then press the + button, then it crashes. Here are the error messages:
Does CSS Transitions work in Fluid Grid Layout? Thank you.

This aging mind gets very easily confused, so please bear with me.
In reply #3, I gave you an answer to you not being able to find the file to delete as in reply #2. Ticking the box next to 'Hidden Items' will allow you to find that file. By default it would be hidden. Ticking the box will not delete the cache file. For that to happen, you need to follow the process as set out in the link supplied in reply #1.

Configurable layout of query panel inputs

How does one configure a query component to allow the view criteria fields in a view object to be displayed in a certain way? I have a business requirement to align 4 input fields side by side and was wondering if there was a way to do this with the query panel as I would like some of the features that come along with it or if I need to attempt this issue another way.
Thanks

Good to know, I will do something similar for a short-term work around but have the feeling I will need to arrange stuff in more details.
It looks like 11gR2 solves this issue with the UI layout tools included but i'm surprised there is not a simple programmatic way to define groups in a query box.

Missing "bookmarks" option in fixed-layout-epub export panel-?

Hi everyone, I'm having an issue exporting a fixed layout epub with bookmarks.
The "Bookmarks" option is not present/visible/showing up in the export options: I only have "none", "file name", "Multi level". But I do have bookmarks in the document.
I had canceled old bookmarks and recreated them, but nothing changed.
I really can't figure out the what the problem is!
Any suggestion will be really appreciated… Thanks.

I understand that you need the newest version (InDesign CC 2014.1) to accomplish what you want with EPUB.
But if you have a Creative Cloud subscription, you can download BOTH that version (the current one) AND also install InDesign CC (which came out in 2013), as well as InDesign CS6. All can be installed simultaneously!
As I described above, I think you unintentionally muffed it by installing a trial on top of your installation. Both should be uninstalled.
Then with Creative Cloud install the latest version and make sure it's working.
To download an older version from Creative Cloud, select the Apps menu in the CC application. Scroll down till you see "Filters & Version" In that section, you will see the older versions which you can also install.

Putting a panel using null layout in in a JScrollPane

Hi,
I'm trying to create a form for the screen which looks exactly like its equivalent on paper. The form has a grid of cells that can be typed into.
My approach so far has been to use a JTextPane for each cell and use absolute positioning to put these onto a JPanel with a null layout.
This has worked well so far, but the JPanel is taller than the screen so I want to put it inside a JScrollPane.
However the scrollbars don't show up.
Can someone point out what I need to implement to be able to scroll my null layout JPanel in a JScrollPane.
Thanks.

That was nice and simple. The Duke's are yours.
One problem leads to another unfortunately.
I want the form to be centered so I put it in another JPanel with BorderLayout then put that in the JScrollPane. Unfortunately it is not centred.
JPanel nullLayoutPanel = new JPanel();
nullLayoutPanel.setLayout(null);
// layout components on panel
JPanel panelToKeepFormCentered= new JPanel(new BorderLayout());
panelToKeepFormCentered.add(nullLayoutPanel, BorderLayout.CENTER);
JFrame frame = new JFrame();
frame.getContentPane().add(new JScrollPane(panelToKeepFormCentered));Hope it is clear what I'm trying to achieve.
When the JFrame is smaller than the form (the nullLayoutPanel), scrollbars should show (they do now thanks to Noah).
When the JFrame is bigger than the form, the form's JPanel should be centred in the JFrame with blank space around.
Thanks.

JTabbed Pane Applet, Panel layout troubles

Why is it not letting me set the layout on the panel that shows up in the tabs? This is driving me nuts :|
import javax.swing.JApplet.*;
import javax.swing.event.*;
import javax.swing.*;
public class UI extends JApplet
public void init()
    JTabbedPane tabbedPane = new JTabbedPane();
    JTextField textfieldA = new JTextField();
    JComponent panell = makeTextPanel("Blah");
    tabbedPane.addTab("One", panell);
   protected JComponent makeTextPanel(String text) {
     JPanel panel = new JPanel(false);
     JLabel filler = new JLabel(text);
     filler.setHorizontalAlignment(JLabel.CENTER);
     panel.setLayout(new BorderLayout()); //Cannot resolve symbol
     panel.add(filler, BorderLayout.CENTER);
     return panel;
public UI()
}

swing is just an extension of awt, but not everything needed to be extended. awt is the only library with BorderLayout.

Layout of panels

Hi
I've just started to use data modeler today (ver2). The layout of the panels started off with the Browser on the left and th design panel to the right.
Something happend (I don't know what), but the Brower panel is on the top and the design panel is on the bottom.
How can I change it back to the origional layout.
Thanks
Brendan

Hi Brendan,
it's standard docking behavior - drag browser window to the left and to center and you'll see blue rectangle that shows possible position for that window.

Panel Stretch Layout - Center facet needs to be adjustable

I am using JDev 11.1.1.3.0; building a public facing website.
I have set up the basic page layout with a Panel Stretch layout with facets at the top, center abd bottom. The top is the header, the bottom is the footer, the center is the content.
The payout needs to adjust based on how much content is contained within the center. Howeverm right now, that is not occuring. What is occuring is that if the content in the center exceeds the initial space, it creates a scoll bar.
I have the PSL contain set for a specific width. If I do NOT specify a height, it simply collapses. If I specify a width, taht width remains fixed.
Am I using the wrong container to define my variable content ?

wait a second here. I am confused.
When you have a normal web page, whether the content is contained within a <div> or a <table>, BOTH of those components strecth to allow the content flooding into them to show. If the content itself exceeds the height of a browser, the browser creates a scroll bar to allow the user to scroll up and down to vie wthe content. All very normal web protocol.
Here, the "PSL" comonent seems to do neither. I created a test page. It has nothing more than a PSL on it, with a TON of text I added in a <verbatim> tag and I put that in the center facet of the PSL.
Not only does the center facet NOT "push" the bottom facet down to reveal ALL of the content of the center div, (it just cuts right off mid-line) but if I remove the bottom facet, the broswer page does not stretch. the content simply runs off the page.
Why?
This should be MUCH easier than this. These ADF components are a joke. This is NOT web 2.0. What am I missing here? I want to design a simple web page where the center facet stretches top to bottom to grown with the content being added. This is my basic page layout:
<markup>
<af:panelStretchLayout startWidth="251px" id="pt_psl1"
endWidth="0px" inlineStyle="width:1000px;">
<f:facet name="start">
<f:subview id="sv2">
<jsp:include page="/fragments/home_side.jsff"/>
</f:subview>
</f:facet>
<f:facet name="center">
<af:panelStretchLayout id="pt_psl2" rendered="true"
startWidth="0px" endWidth="0px"
bottomHeight="0px" topHeight="99px">
<f:facet name="center">
<af:facetRef facetName="main"/>
</f:facet>
<f:facet name="top"><f:subview id="sv1">
<jsp:include page="/fragments/head_top.jsff"/>
</f:subview>
</f:facet>
<f:facet name="end"/>
</af:panelStretchLayout>

</f:facet>
</af:panelStretchLayout>
<af:panelStretchLayout id="footer_psl" topHeight="30px"
inlineStyle="width:1000px;height:30px;"
bottomHeight="0px">
<f:facet name="top">
<f:subview id="sv3">
<jsp:include page="/fragments/footer.jsff"/>
</f:subview>
</f:facet>
</af:panelStretchLayout>
</markup>
the facetref named "main" is where I am dragging portlets. Some of those portlets contain a little data, some contain a lot. Either way, the page needs to strectj to accomodate the data.
Can this even be DONE? If so, what am I missing?

Panel layout not remembered

I have Photoshop CS4 in Windows XP. A problem has developed with remembering the layout of docked panels.
After the window is minimized, or the program is restarted, the bottom 3 panels are reduced to single lines (containing the tabs), and the other panels are expanded to fill the space.
I can re-expand a panel by double clicking the line, are restore the layout by loading the saved workspace, but it's tedious to have to do this each time the program is restarted or restored.
'Remember Panel Locations' is checked in the Preferences.
The problem may have developed when I temporarily set the screen to a lower resolution in order to test the behaviour of another program.

Noel Carboni wrote:
By the way, resetting the preferences with Photoshop CS4 or CS5 is a bit simpler than finding a file to delete...
Hold down Ctrl-Shift-Alt while starting the program. You'll be prompted to delete the settings file.
It's been like that since I started with PS 3.0!

ADF/Swing probles with nested panels layout.

When panel is placed in other panel, changing of nested panel layout by changing panel properties, results in adding in jbInit() metod code for setting choosen layout at the end of jbInit and not (as in top panel) at the begining of jbInit(). Many times (for instance when layout is BorderLayout) because of this nested panel is displayd empty. It is necessary of course to manually move lines setting layout before lines which adds components to nested panel. Thou it is possible to do it manually it would be nice not to have remember about it.

Remi,
how do I reproduce this? Can you give me a step-by-step instruction? Its not clear from your posting which JDeveloper release you are using (though I assume JDeveloper 10.1.3), nor if the panels are created in external Java file or within the parent panel.
