I'm trying to put a text box (custom rendered) into a ScrollPane except when I hit space to put a space into the text box, space is also the hotkey to scroll down in the scroll pane so it enters the space and than scrolls down in the scroll pane. How do i remove the hotkey that space scrolls down in the ScrollPane? I've been searching through ScrollPane looking for anything relating to vertical scroll bar or hotkey but didn't find anything.
See this link
JavaFX: scrolling vs. focus traversal with arrow keys
i think it's what you want ,try to change switch-case method with something like this
switch (event.getCode()) {
Case SPACE:
...
}

I have a scroll pane that the scrolls show up only when elements like buttons start to disappear, which is pretty small. I want to control when the scrolls show up so they'll appear earlier.
I couldn't find a way to it, is there a property or listener to do this?
I want scrollable panes.
Please, have a look at the picture
As you can see at the Navigator, I used Tabbed Pane, then placed Scroll Panes on it. Then placed Panel on it. And then added Lables. Looks like I'm trying to reach my left ear with my right foot. But without the jPanel1 my lable occupied the whole panel size.
Well now my scrollable panel doesn't work well.
It is visible at this .
Well, I made the window narrow. But the scroll bar at the bottom doesn't allow me to reach what is behind the border further on the right. And this scrollbar seems strange. It has only t left arrow. No right one. And no vertical scroll bar if I make the window less high.
Could you give me a hint how to make scrollable windows?
I'm not sure what you're doing wrong this is the results I get when I do only this and nothing more.
Drag and drop a tabbed pane to the frame
Drag and drop a scroll pane to the tabbed pane
Drag and drop a panel to the scroll pane
Drag and drop a label to the panel, and another label to the bottom.

I have a JScrollPane with a View. I'm doing a chat application , it's why i need to have my ScrollBar to the Maximum(). To get the right Maximum of the View i have to validate before. When I validate my ScrollPane an automatic repaint is doing. I don't want this repaint because it makes a double repaint when i set the ScrollBar to the Maximum : when the ScrollBar is at the top and a another when it is a the bottom.
my code :
Main.getWindow().getMainPanel().getScrollPaneCenter().validate();
scrollPaneCenter.getVerticalScrollBar().setValue(scrollPaneCenter.getVerticalScrollBar().getMaximum());
PS : I want to disable the repaint of my conponent or maybe you have a solution to have a reversed JScrollPane( to always have the ScrollBar to Bottom) .

I'm guessing your are using a a JTextArea or JTextPane.

You don't need to validate or set the scrollbar manually. You juat append the text to the bottom of the Document. See Text Area Scrolling for a couple of solutions.
In windows, Java, etc, the scroll pane scrolls the widgets inside. What I'm wondering is, how exactly does it do its scrolling? Does it change the location of each nested widget, or does it have a content widget that it moves around? Or is it something else? Also, when both scrollbars are present, how does it mask that little square at the bottom right? That square is sometimes used to resize. Is it a separate nested widget?
Thanks
I think it just changes the location of the widget, button, or thing-a-ma-bober.
But my second guess would be it just draws the components "outside" of the scroll pane without being seen and when you scroll it just redraws dynamically.
Right now I have a JTextArea inside of a JScrollPane. For the current content it has both a vertical and horizontal scroll bar showing up. I'm trying to implement a search functionality where a user can search for a certain string and it will set the caret position to the first occurrence of that string. However it seems that JScrollPane only scrolls vertically when I set my caret position. So matching strings going off the JTextArea horizontally will completely get missed and the horizontal scroll bar won't scroll at all.
I'm using the basic function
setCaretPosition() for the JTextArea
Does anybody have any idea why my JScrollPane isn't moving horizontally using setCaretPosition()
Edit:
It appears the horizontal scroll bar is scrolling but it moves so little that it's barely noticeable. I can only see the very first pixel of the character. Is there a way to have the scrollbar center (or as much as possible) to the caret position?
You should be able to use the Visible Caret Listener.
Or you can also look at Center Line in Scroll Pane. It only centers the line vertically, but you could customize the code to do horizontal as well.
