            Java JTextPane does not update its size when Character Attributes change
            Asked 2021-Jan-19 at 09:35

            I am programming a Swing based UI Component in Java 8, that basically displays multiple JTextPanes in a vertically scrollable Field and has a Toolbar for basic style manipulation (Font, Font Size, Bold, etc.)

            For this I am using a JPanel, which also implements Scrollable inside a JScrollPane, that contains multiple JTextPanes using a vertical BoxLayout.

            When I start this, it looks fine and all TextPanes are high enough to fit one line of text and scale when more is typed. The Problem occurs, when I change the font size. When the font size changes, the JTextPane should automatically resize to fit the new text, but when I use a button to change it, the size only changes when I click it twice.

            Here are some screenshots to explain what I mean:
            This is after the example starts, and I add some text to the top JTextPane. There are 2 TextPanes here.

            This is after the first click to the button, which sets the font size to 30pt. The text is larger, but the JTextPane does not resize to fit it

            And this is after I click the button again. The JTextPane now scaled correctly

            I already tried to call invalidate, revalidate and repaint manually on the JTextPane and its parents, but that had no effect.

            The JTextPane also resizes when another Attribute is changed (e.g. bold) or the FontSize is change to another value. But it seems to always be one change behind.
            So when the FontSize is changed to 20, then to 30, it will resize to fit 20pt font when the FontSize is set to 30pt.
            Does anybody have an Idea what could cause the problem and how I can fix it?

            Here is the code of the minimal example:

            I modified your code to create this GUI.

            The main change I made was in your ActionListener. By using the StyledDocument setCharacterAttributes method, I didn't have to select the text first. It appears that setting the JTextPane font size caused the JTextPane to resize properly.



            JComponent fails to initialize with: java.lang.IllegalArgumentException: Width and height must be >= 0
            Asked 2020-Mar-13 at 14:17

            I have an installer created with install4j that fails to show anything at all, other than the background image, on a screen that contains a Installation Directory Chooser component that as far as I can tell from the stack trace is based on a Swing JComponent.

            The problem only occurs on a specific Windows Server 2016 server and no other environment I've ever tested it against. There are other components on the same screen but through trial and error I found out that everything shows up fine once I disable/don't build the above JComponent/Directory Chooser.

            Here's the stack trace:

            It ended up being related somehow to windows user permissions/settings.

            The installer/executable user that was having this issue ended up running the executable with a different windows administrator user and it all worked well.

            Both users were admin users so I would have to dig around more to find the differences in user permissions and how they affected this issue.



            Limit Jscrollpanes width to Parents width when dynamically adding content
            Asked 2020-Jan-12 at 01:02

            Hey i am new to this

            I want dynamic content to be as wide as the parent window(and automatically resize with its width) but able to scroll down if needed(if content exceeds available space).

            I am adding and removing multiple things like Jpanel or JinternalFrame to a JScrollPanel.

            Most things whether custom classes or layout manager i tried, either only hid the scrollbar( but did not prevent content being added in horizontal direction forever) or did only shrink the content.

            i tried but it only stretches or shrinks

            RadGanttView - Expanding nested RecurringTask - Error
            Asked 2018-Mar-16 at 10:16

            I'm having some problems with the telerik:RadGanttView control. I believe this to be a problem specific to the Telerik toolkit UI for WPF, but I'll explain the issue as detailed as possible so others might be able to suggest a workaround if they can think of one.


            The GanttView has the possibility to display recurring tasks by placing each recurrence as a child inside a single parent event. Now my project requires me to nest this recurring task series into another parent event container.

            When selecting a recurring task event that is part of a nested hierarchy (of at least 2 levels deep), the application will throw a System.NullReferenceException and crash.
            More specifically, this error occurs only when all parent nodes are collapsed. If only the top node is collapsed and the other child-nodes are still expanded, the problem does not occur.

            This is the StackTrace of the System.NullReferenceException:

            System.NullReferenceException was caught

            Detailed description:

            I've based my code on the RecurringTask_WPF example project. I was able to get my desired visual result but I've stumbled upon an action that causes my application to crash.
            This makes it pretty much unusable, so I need to find a solution or at least a way to catch the exception and prevent it from crashing.

            I've been able to pinpoint the cause of my problem, but have been unable to solve this by myself.

            Let me start by describing my current situation/environment.

            In the default RecurringTask_WPF example project, if you collapse the "Recurrence Series" (the parent tree node) then you can see all the child recurring tasks next to each other.
            When you click on one of the events, so for example: "Recurrence 1" block (in the TimeRuler Part of the RadGanttView), then this specific recurring task gets selected. This causes the tree node to be expanded automatically and the selected task/event becomes highlighted.

            This behaviour works perfectly as intended and I wish to keep it like that exactly.
            However once you nest recurring tasks into one extra level of hierarchy, which is on my requirements, an exception is thrown and the program stops working.

            First I'll give you the code that changes the example project in order to recreate the problem. (This should also help with explaining the exact problem further)
            You should replace the GetTasks() method of the ViewModel.cs with the code below:

            I've reported this issue on the official Telerik forum and received the following response:

            I checked your description and I can confirm that there are two separate issues that can be reproduced with the provided steps. I logged two issues in our feedback portal and updated your Telerik points.

            I am afraid currently, I cannot suggest a workaround for resolving this. That's why I would recommend you to follow the items in the portal.

            I know answering your own question is frowned upon. However, I'll follow the development and will update this answer if anything changes.

            If anyone else finds a workaround before this gets fixed, please do share.
