How can I create a status bar at the bottom of a window ?
I would like to create a status bar at the bottom of my main window similiar to "Internet explorer" has. I thought of using a tool bar but I can't see how to keep it positioned at the bottom of the window when the window is resizable. Any other ideas on how to do this the bar only needs to contain a small amout of text and maybe an icon or two.
CVI doesn't have a status bar control on UI element like the one available in Visual Studio++. The best way to replicate this is most like through a string control that is resized and positioned to remain at the bottom of the window and colored to look appropriately. I have also seen the combination of a decoration and a text message used.

How can I implement a status bar at the bottom of a resizable application?
Hello all,
I am a JavaFx newbie and I am implementing an application (a Sokoban game), with a menu at the top of the frame and a gaming area covering the rest of the frame. To support the game, I have to load images at certain positions in the gaming area.
The game also includes a level editor with another menubar and where images are set to other positions.
I implemented this in another view, swiching from the game mode to the level editor mode and vice versa is just done by setting the other view visible. Up to now this works, here the important statements building these details:
Group root = new Group();
gameView = new Group(); // for gaming mode
le_view = new Group() // for level editor mode
MenuBar gameMenubar = new MenuBar();
Menu menuGame = new Menu(bundle.getString("MenuGame"));
... building the menu items and menues ...
gameView.getChildren().add(gameMenubar);
ImageView buildingView[][] = new ImageView[22][22];
for (nCol = 0; nCol < 22; nCol++) {
for (nRow = 0; nRow < 22; nRow++) {
buildingView[nCol][nRow] = new ImageView();
buildingView[nCol][nRow].setX(nCol * 26 + 5);
buildingView[nCol][nRow].setY(nRow * 26 + 40);
gameView.getChildren().add(buildingView[nCol][nRow]);
gameView.setVisible(true);
root.getChildren().add(gameView);
... same stuff to build the le_view ...
le_View.setVisible(false);
root.getChildren().add(le_View);
Scene scene = new Scene(root, 800, 600, Color.CORNSILK); Now I want to introduce a status bar at the bottom of the frame, which of course has to follow the bottom of the frame, if it is resized. And of course the menu and the status bar should not grow vertically, if the height of the frame is increased.
The implementation seems to be easy with StackPane for the frame and one BorderPane for each mode.
For the first step I only tried implementing the game mode with only one BorderPane (just setting the menu, the gaming area and the status bar each into a HBox and setting these three HBoxes at the top, into the center and at the bottom). I also tried this via GridPane and via VBox; I always get any erroneous behaviour:
Either the menubar is visible, but the menus do not pop up the menu items, or the anchor point of the menu and of gaming area are set 100 pixels left of the left frame border and move into the frame when the frame width is increased, or the menu is set 20 pixels below the top of the frame, or HBox with the menu grows when the frame height is increased, so that the anchor point of the gaming area moves down.
Can you describe me a correct construction of such a frame? Thanks in advance.
Best regards
GerhardHello Gerhard,
Glad the code helped, thanks for a fun layout exercise.
For the draft code I just pulled an icon off the internet over a http connection.
If you haven't done so already place any icons and graphics you need local to your project, so that resource lookups like:
Image img = new Image("http://www.julepstudios.com/images/close-icon.png");become
Image img = new Image("close-icon.png");then performance may improve.
Another possible reason for your performance problem could be that when you use a vbox, the vbox content can overflow the area of the borderpane center and might be sitting on top of the menu pane, making you unable to click the menu (which is what happens to me when I try that with the draft program with the vbox wrapping mod, then resize the scene to make it smaller). This was a trick which caught me and the reason that I used a Group originally rather than a vbox. I found a vbox still works but you need to tweak things a bit. The trick I saw was that the order in which you add stuff to the borderpane is important. The borderpane acts like a stack where the last thing added floats over the top of everything else if you size the scene small enough. For your project you want the menu on top always, so it always needs to be the last thing added to the borderpane, but when you swap in the level pane for the game pane, then back out again, the game pane can end up on top of the menu which makes the menu seem like you can't click it (only when the scene is sized small enough). It was quite a subtle bug which took me a little while to work out what was happening. For me the solution was to add just one vbox to the center of the border, and then swap the game pane and the level editor in and out of the vbox, that way the center of the layout always stayed behind the menu bar and the status bar.
I added some revisions to reflect the comments above and placed some comments in the code to note what was changed and why.
public class SampleGameLayoutRevised extends Application {
public static void main(String[] args) { Application.launch(args); }
public void start(Stage stage) throws Exception {
final BorderPane gameLayout = new BorderPane();
final Group gameView = new Group();
final MenuBar gameMenubar = new MenuBar();
final Menu gameMenu = new Menu("Mode");
final VBox centerView = new VBox();
centerView.setStyle("-fx-background-color: darkgreen"); // we set a background color on the center view to check if it overwrites the game menu.
MenuItem playGameMenu = new MenuItem("Play Game");
MenuItem levelEditMenu = new MenuItem("Edit Levels");
gameMenu.getItems().add(playGameMenu);
gameMenu.getItems().add(levelEditMenu);
gameMenubar.getMenus().add(gameMenu);
final StackPane levelEditView = new StackPane();
levelEditView.getChildren().add(new Text("Level Editor"));
ImageView buildingView[][] = new ImageView[22][22];
Image img = new Image("http://www.julepstudios.com/images/close-icon.png"); // use of http here is just for example, instead use an image resource from your project files.
for (int nCol = 0; nCol < 22; nCol++) {
for (int nRow = 0; nRow < 22; nRow++) {
ImageView imgView = new ImageView(img);
imgView.setScaleX(0.5);
imgView.setScaleY(0.5);
buildingView[nCol][nRow] = imgView;
buildingView[nCol][nRow].setX(nCol * 20 + 5);
buildingView[nCol][nRow].setY(nRow * 20 + 40);
gameView.getChildren().add(buildingView[nCol][nRow]);
final VBox statusBar = new VBox();
final Text statusText = new Text("Playing Game");
statusBar.getChildren().add(statusText);
statusBar.setStyle("-fx-background-color: cornsilk"); // we set a background color on the status bar,
// because we can't rely on the scene background color
// because, if the scene is sized small, the status bar will start to overlay the game view
// and if we don't explicitly set the statusBar background the center view will start
// to bleed through the transparent background of the statusBar.
gameLayout.setCenter(centerView); // we add the centerview first and we never change it, instead we put it's changeable contents in a vbox and change out the vbox content.
gameLayout.setBottom(statusBar);
gameLayout.setTop(gameMenubar); // note the game layout is the last thing added to the borderpane so it will always stay on top if the border pane is resized.
playGameMenu.setOnAction(new EventHandler<ActionEvent>() {
public void handle(ActionEvent event) {
centerView.getChildren().clear(); // here we perform a centerview vbox content swap.
centerView.getChildren().add(gameView);
statusText.setText("Playing Game");
levelEditMenu.setOnAction(new EventHandler<ActionEvent>() {
public void handle(ActionEvent event) {
centerView.getChildren().clear(); // here we perform a centerview vbox content swap.
centerView.getChildren().add(levelEditView);
statusText.setText("Editing Level");
playGameMenu.fire();
Scene scene = new Scene(gameLayout, 800, 600, Color.CORNSILK);
stage.setScene(scene);
stage.show();
}Other than that I am not sure of a reason for the slowdown you are seeing. In my experience JavaFX has been quick and responsive for the tasks I have been using it for. Admittedly, I just use if for a bunch of small trial projects, but I've never seen it unresponsive for a minute.

How can I provide Horizontal tool bar at the bottom of the form?
Hi Friends,
I have form with 8 tab pages. I created a horizontal toolbar canvas with some navigational buttons. I want to put the horizontal toolbar at the bottom of the form which is common to all of my tab pages of that particular form.
How can I do that?
Thank You.
Gopinath KonaIam not very sure...but let me give it a try. As far as my knowledge goes, horizontal tool bar can be placed only the top side of the form.
For your requirement, u can probably try out placing the buttons on a stacked canvas and display the same for every tab page in your form...

With two or three pages open, I have scroll bars that allow me to see the right side of the other pages, but not on the Firefox page.
Thank you for the reply, Fred, but when I went to my saved screenshot, I realized that the shortcut on my desktop had opened in IE, not Firefox. There is no scroll bar and the directional arrows do not work. My daughter has been playing with my laptop again. When I set up the same conditions with Firefox, there is no scroll bar, but the arrows function properly, so I can read to the right edge of the page. Now to find someone who knows IE11. Thanks again, for your reply.

We're creating pages from a template in DW3. The template includes a header, footer and a navigation bar. We've made the navigation bar an editable region so that we can change the down state of the buttons on pages where it is required. However, when we make a new page from the template and try to change the behaviors of the buttons in the navigation bar it will not allow us to make those changes.
Have you considered using CSS styled text/list menus instead of image rollovers. It isn't hard really and it's actually a much better choice for web accessibility and for search engines to find and follow your links. Here are some links to several CSS menu systems you can try:

How can I create JEditorPane which scrolls to the bottom on every resize?
JRE 1.3.0
Included a simple frame with the only control - JEditorPane (contained within JScrollPane). Every time scroll pane size changes, attempt to scroll down to the end of JEditorPane is made.
The problem is: although everything works 9 times of 10, sometimes editor is scrolled almost to the end, sometimes - to the very top. On the next resize editor is scrolled correctly.
I think, there are some delayed layout recalculations inside SWING which prevent JEditorPane and/or JScrollPane from knowing actual size.
Is it possible to force JEditorPane+JScrollPane pair to update dimensions? ( explicit call to doLayout() does not fix anything )
Thanks

How do I keep my status bar at the top and not moving from side to side and bottom of phone
how do I keep my status bar at the top of my phone? I let my grandsn play a game on my phone and after he gave it back I noticed my status bar would move from the top to the side or bottom etc
Reset, hold both home and power buttons until the iPhone begins to restart itself, ignore the slide to power off slider. Let the iPhone restart itself. Usually takes about 10 seconds of holding both buttons.
Probably do not need this, but Portrait Lock can be set by, pressing home button twice quickly, slide bottom row of icons to the right one time, tap the Portrait Lock icon. -

How can i create a new item in the app "health"?
how can i create a new item in the app "health"? I need a field for documentation of "Waist-to-height ratio", exactly for "circumference".
It's a matter of common knowledge, that the Waist-to-height ratio (WHtR) has more significance then the Body-Mass-Index (BMI).If you mean you want to change a color of a calendar category or create a new one, you cannot do that, what is pre-loaded is what you get and cannot be edited.
