Set minimum size of JScrolPane's knob

Hi All,
Please suggest me a way to set a minimum size of JScrolPane's knob.
It becomes very small when the numbers of items in the list are so much and that time knob is very small. that makes scrolling difficult to the user.
So i want to set a minimum size of the knob.
Please suggest the snippet of code for that

One posible solution is to add a ComponentListener to the
JFrame that implements ... (struggles to remember) ...
componentResized().
Inside componentResized(), check the size of your JFrame,
and if it is smaller than your preferred minimal dimension,
resize it up to your minimum.
// in the constructor, perhaps, or initialization routine
addComponentListener(
newComponentAdapter()
    public void componentMoved(ComponentEvent e)
        Dimension size = e.getComponent().getSize();
        size.width = Math.max(size.width, myMinimalWidth);
        size.height = Math.max(size.height, myMinimalHeight);
        e.getComponent.setSize(size);
}); Pity there's no setMinimumSize() like the JComponent class.
Best of luck !

Set minimum size for GridBagLayout

Hi all,
I have a dialog which using GridBagLayout. I spent quite a lot of time to test, but still got the following problems. Could anyone give me some solutions?
1. How do I set the dialog to have a minimum size ?
Since the dialog is sizeable, so I have to make this limitation to prevent the dialog being too small .
I tried the following code:
        this.getContentPane().setMinimumSize(new Dimension(686,520));
        this.setMinimumSize(new Dimension(686,520));but it's still not work... , I can still resize it too small.. any other way ?
2. How do I set its default size when dialog pop up?
I don't know why the dialog always auto popup in maximum size.
I have tried to use this.setSize(new Dimension(686, 536)); inside jbInit() function, but still not work...
Please help ... Thanks a lot.

Why dont you try this.setResizable(false);?
Anyway I have given a sample program here using Gridbag layout and this dialog cannot be resized.

How to set minimum size for the 'location' box in toolbars?

I reorganized my toolbars by merging the location and tabs bar. I have the location on the left hand side and the tabs *next* to it, like this:
[ (<)(>) [LOCATION] /tab\/tab\/tab\ ]
Unfortunately when the number of tabs increases, the location box becomes so small that I cannot even see the url of the site I'm in...
Is there a way to force a minimum width for the location box? I couldn't find a setting in about:config for it (I imagine that this would be a browser.urlbar setting)

You rock! The combination of fixed width tabs with the stylish Add-on, and the single line of script below just made my day!
#main-window[sizemode="maximized"] #TabsToolbar, #TabsToolbar > #urlbar-container { min-width: 350px; }
Many thanks!

Have JFrame respect the minimum size (stop resizing) - Partial solution

Hi
I remember I searched for a solution to make JFrame respect the minimum size of itself or it's components, but unfortunately there is no solution, at least not a satisfactory one.
The force-a-resize-if-it-gets-too-small "solution" looks really bad so I desided to drop the whole thing.
However I've been testing around with different Look & Feels and changing the layout, and what I discovered is that when setting setDefaultLookAndFeelDecorated(true) the minimum size is respected.
I haven't seen anyone mentioning this I thought I'd post it here.
import javax.swing.*;
import java.awt.*;
class RespectMinimumSize extends JFrame {
    RespectMinimumSize() {
     setMinimumSize(new Dimension(400, 400));
     setLocationRelativeTo(null);
     pack();
     setVisible(true);
    public static void main(String [] args) {
     JFrame.setDefaultLookAndFeelDecorated(true);
     JDialog.setDefaultLookAndFeelDecorated(true); // Works with JDialog as well
     Toolkit.getDefaultToolkit().setDynamicLayout(true);
     new RespectMinimumSize();
}

thanks - initial testing seems to work OK.
(I had to add a panel, to be able to set minimum size to the panel)

Stage should respect minimum size of its content

Hi,
I wonder if there was a standardized approach to make the Stage inherits its minimum size from its content.
I tried to bind the Stage's mimimumWidthProperty to StackPane equivalent but without any success.
The only way I found was to 'force' the size by explicitly call stage.setMinWidth(), but this not really dynamic.
For information, the preferred size works fine and is well managed by the Stage.
Thanks.
If the following example, the Stage does not respect the minimum size set on the StackPane:
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public class TestMinSize extends Application {
    @Override
    public void start(Stage primaryStage) {
        Button btn = new Button();
        btn.setText("Say 'Hello World'");
        StackPane root = new StackPane();
        // set minimum size
        root.setMinWidth(200);
        root.setMinHeight(200);
        root.getChildren().add(btn);
        Scene scene = new Scene(root, 300, 250);
        primaryStage.setTitle("Hello World!");
        primaryStage.setScene(scene);
        primaryStage.show();
}

The only thing that springs to mind is binding the properties to substract the decoration size of the stage.
But this wouldn't take into account if a child node of your root node has a minWidth/Height larger than the root's.
And generally this only works if root has a minSizeProperty, but Scene.getRoot() is a Parent.
primaryStage.minHeightProperty().bind(primaryStage.heightProperty().subtract(scene.heightProperty()).add(root.minHeightProperty()));
primaryStage.minWidthProperty().bind(primaryStage.widthProperty().subtract(scene.widthProperty()).add(root.minWidthProperty()));Or slightly more general:
public static void respectMinimumSize(Stage stage) {
     Scene scene = stage.getScene();
     if (scene.getRoot() instanceof Region) {
          Region root = (Region) scene.getRoot();
          stage.minHeightProperty().bind(Bindings.max(0, stage.heightProperty().subtract(scene.heightProperty()).add(root.minHeightProperty())));
          stage.minWidthProperty().bind(Bindings.max(0, stage.widthProperty().subtract(scene.widthProperty()).add(root.minWidthProperty())));

How to set a minimum size of a JFrame

hi freinds,
i have written a swing application which starts like this ,
public class workerclass extends JFrame implements ActionListener {
blah blah blah ..
now can you please tell me how to set a minimum size for this application once it starts so that user cant minimize it more than that minimum size.....
when i tried
setDefaultLookAndFeelDecorated(true);
it did my job by setting it to a particular size which wasnt minimizable, but this default look and feel looked ugly.
so i used system look and feel
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
but with this how do i set the minimum size..
please do help
and one thing more , like
in my main Method when i say
new workerclass().setSize(500,500); or say(100,100) or say(300,300)
new workerclass().setVisible(true);
the size (***,***) , doesnt reflect when my application starts, it always starts with some damn fixed size , what can be the issue .
waiting.........
Thanks

How can I set the minimum size the location bar should automatically resize to

I have moved all of my navigation buttons, location bar and tabs to be in line. This has been done to maximise the available space on screen.
This works perfectly with two or three tabs open, but once more tabs are opened the location bar automatically shrinks to allow for more tabs and becomes unusable. I want to set the minimum size the location bar should shrink to but I do not know how to do this.

Any help would be appreciated.

FBZP seems to be the only way to do the minimum amout setting in standard SAP.
You can check the BTE (Business transaction event) 00001820 for excluding the low amount items in F110. Please search SDn on how to use the BTEs.

You can't set it, but you can control it by adding a component listener to the JFrame:

How to set minimum height size for an empty XML Form iview

Hi,
I'm trying to configure the minimum height size of an XML Form iview without sucess. Even when there is no content to show, iview height size is around 80 pixels. When there is content the automatic configuration works fine and the iview is resized properly.
The iview has automatic size and the minimum size for automatic is with 5 pixels...
Any ideas?
Thanks,
Marcelo

How to set the minimum size of app window?

Hi JavaFX experts :)
Is it possible to limit the minimum size of application window? What would be the JavaFX equivalent of the following SWING code?
        JFrame frame = new JFrame("Application Title");
        frame.setMinimumSize(new Dimension(320, 240));
        frame.setPreferredSize(new Dimension(640, 480));Preferred or initial size was easy (width/height), but what about the minimum size?
Stage {
    title: "Application Title"
    width: 640
    height: 480
    scene: Scene {
        content: [
            // some content
}Thanks!

var stage: Stage;
var stageWidth = stage.width on replace
    if (stageWidth < 640) stageWidth = 640;
var stageHeight = stage.height on replace
    if (stageHeight < 400) stageHeight = 400;
stage = Stage {
    title: "Application Title"
    width: bind stageWidth with inverse
    height: bind stageHeight with inverse
    scene: Scene {
        content: [
            // some content
}It doesn't prevent resizing to smaller dimensions but it restores to minimal dimension if done.

Setting a JLabel's minimum size

Hello,
I have a container with a GridBag layout, and when I resize to a size wher everything fits its fine, but on the bottom of the window I have a JLabel, which can be quite large sometimes. When it is large, its minimum size is the length of the string, so when I resize its container i get some big ugly scroll bars and its contents dont get any smaller, although every other component can be much smaller.
What I would like is for the JLabel to have a minimum size (say 100 pixels) and if the window is resized less than this, introduce scroll bars, otherwise just cut off some of the text, as the label isn't very important!
I have tried loads of different stuff, the most obvious being JLabel.setMinimumSize(new Dimension(100,16)); but nothing seems to have worked, can anyone help?

         public void updateVideoInfo(){

          videoInfo.setText(str);
          int width = this.getSize().width - play.getSize().width - stop.getSize().width;
          videoInfo.setPreferredSize(new Dimension(width-15,16));
     public void validate(){
          updateVideoInfo();
     }I did a quick work arround, which I had tried before but didnt work for some reason... but has now
But this would be awfull to change If i ever add anything in the future so I will look at what you said!

How to set the size for height of iView tray?

Hi,
I have created a ABAP webdynpro component and integrated this comp with iView. Then i integrated iView into Page in portal. That is working fine.
But the size of tray/window which is displayed in the page is very small.
How to increase the height of that Tray/window/iView containing my component?

Hi,
By changing the maximum automatic height and Minimum automatic height property of the iview you can set the size for height of your iview.
to do this follow the setps:
goto content administrator -> portal content -> your folder where you created your iview or directly to your iview -> right click -> open -> object,
and now in property category choose appearance-Size from the drop down menu and set the above properties to your required height.
if you want the end user to modify this property set the property to read/write .
