I creating site builder and I want anchorpane at center of another pane. I have 3 anchor panes in SplitPane and in the central pane I need rezise of object like scene builder have when you resize scene builder. How to make that resizing? Is it very hard? I want to make this in fxml or directly in scene builder. I use IntelliJ.
This picture is show how it look when you open at first time and it need to be always 16:9 (central pane). Maybe you know what pane can be it
And this is how it look when you open in full-screen
In this example I tried to use borderPane and I put empty anchorpane's in all other corners because when you put something in center it fit all borderPane. How I remember when you do this thing in anchorPane with constraints (like 100px from upper corner) it looks the same.
How to do normal 16:9 all-time resizing?
I'm building a JavaFX desktop app using scenebuilder for the UI.
Here i have a tilepane inside of a scrollpane, i couldnt use the "fit to parent" option from the context menu in scene builder, i guess the solution is to give them -fx-id's and bind their width in the controller ?
I dont want to use any values so it all comes together nice when the user resizes the window.
how should i go about doing this?
I'm working on a Slotmachine with QGraphicsScene and -View and I'm close to the end of that project. But now I want to add a small rect to the winning-lines that shows the amount of won credits in that line. The rect is a QLabel in a QGraphicsProxyWidget. I don't know if thats the best way to solve this problem but I'm not able to find a better solution at the moment. I'm setting the proxyWidget to not visible in the constructor of the label but when I'm setting this proxyWidget to visible other proxyWidgets in the scene disappear. And I just dont understand why. It's not hiding every proxyWidgets.
As you can see on the picture there's a red rect in the middle of the first square of the winning line. This is causing the problem. It is hiding the lower white border which is a QGraphicsPixmapItem and the first of the normally three QGraphicsProxyWidgets at the bottom, stake(this is not visible), last gain(letzter Gewinn), credit(Guthaben). I don't know why its not hiding the other Widgets on the bottom because they are all equal. As you can see its not hiding the complete lower border. I just don't know why this happens and why it just happens to the lower border and the left widget on the bottom and not to any other elements. I just don't know how to fix a problem like that.
It's a bit long to read but I don't know how to really describe the problem or how I could show you in the Code. I hope someone could help me.
Solved it by using an QGraphicsTextItem. totally forgot that it is existing. Thanks to the QT Forum.
I'm trying to develop a desktop app using javaFX (2.2), and I'm experiencing some difficulties to really get it to behave like I would like it to. Being a new user of the framework, I might not be using it as it should be...
What I want is a kind of dashbord, with several JavaFX or custom controls inside a ScrollPane. I currently have several views that look like this :
<AnchorPane id="userContent" xmlns:fx="http://javafx.com/fxml" fx:controller="squalp.view.OrgViewController">
<children>
<ScrollPane fx:id="scrollPane" styleClass="transparent" hbarPolicy="NEVER" vbarPolicy="AS_NEEDED" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0">
<content>
<VBox fx:id="vBox" styleClass="transparent" alignment="TOP_LEFT" focusTraversable="true">
<children>
<Label text="Label" />
<Button fx:id="bTest" text="Test" onAction="#test"/>
<TreeView fx:id="orgTree" focusTraversable="true" />
</children>
</VBox>
</content>
</ScrollPane>
</children>
</AnchorPane>
As long as I keep using simple controls, no problem, items are correctly placed one after another in th VBox.
But when using TreeViews or TableViews, I can only get my controls to have fixed height, meaning extra space on the bottom, or new scroll bars, in addition to the main one. What I would like to achieve is to adapt my controls to their current content height.
Qt's QML, for exemple, has a childrenHeight property, and it's kind of what I'm looking for. I figure this content height must be calculated somehow, since components scrollbars do adapt to the content.
I had to use a workaround for tableviews :
table.setPrefHeight(list.size() * rowHeight + headerHeight);
but I couldn't find a way to track displayed items on a treeview.
Has anyone an idea of what I could be doing to handle this issue ? Or I am really not using the framework as I should ?
Thanks in advance.
EDIT : Visual description of the problem :
Case 1
Here my treeview's height is set to a default value. There are not enough items to fill the treeview : if I want to put another component below, there'll be a gap; if my scene is not big enough, the ScrollPane's scrollbar appears, even though all the displayable content is visible.
Case 2
If if expand my treeview's items, there are now too many of them. They are not all visible at once, and the treeview's scrollbar appears, even though I already have a scrollable view with the scrollpane.
What I would like is my TreeView to adapt to its content height (reduced height if items are collapsed, bigger height if they are expanded), in order to be able to put several components one after another and to scroll through them all using the ScrollPane's scrollbar.
Since the TreeView component has itself a scrollbar, its visible content's height must be calculated at some point (since scrollbars basically use ratios based on contentHeight/componentHeight). This information doesn't seem to be available in the public API, but I wonder if, developping a custom class that expands TreeView, there could be a way to bind my component to its "visible height".
There maybe a proper way to achieve your goal, but I can suggest the approach similar to tableview's.
orgTree.prefHeightProperty().bind(orgTree.impl_treeItemCountProperty()
.multiply(treeRowHeight)); // treeRowHeight maybe 24.
Note that this is only a workaround where the deprecated and internal use-only method is used, which maybe removed in future releases.
I was looking for way to make TreeView auto-resize to fit its content, e.g. when a node is expanded or collapsed. Here's what I eventually do. Note the Platform.runLater() is required, thus simple property binding would not work here. Also note the cellHeight is the height of a tree node. It's beyond the scope of the question here how to get that.
treeView.expandedItemCountProperty().addListener((obs, oldV, newV) -> {
Platform.runLater(() -> {
treeView.setPrefHeight(newV.intValue() * cellHeight);
});
});
You can use the binding property of the view to the childs height property. By this, whenever the height of the Parent changes, childs height will automatically change ! This is not automatic height adaption, like you want, but a forced adaption, which will help you !
Width property is also available
Basically this is a snippet that will help you :
pane.heightProperty().addListener(new ChangeListener<Number>() {
#Override
public void changed(ObservableValue<? extends Number> arg0,
Number oldValue, Number newValue) {
table.setPrefHeight(newValue - 200);/*The difference of height between
parent and child to be maintained*/
}
});
I cannot set the background color of a ScrollPane in the latest version of JavaFX 8 (java 8 b-110 and above versions). So I need to know whether this is a permanent issue or temporarily (which can be Fixed in later versions)?
I ended up using -fx-background:green; instead of -fx-background-color:green; because -fx-background-color only set the colour for the borders of ScrollPane.
It looks like some additional CSS is needed in order to be able to set ScrollPane backgrounds to whatever color you like. See this question:
