### Apache Hop version? 2.20.0-SNAPSHOT ### Java version? 21 ### Operating system Windows ### What happened? The About dialog (Help > About) takes a noticeable time to open in Hop Gui on Windows. ### Cause In `AboutDialog.open()` the "Advanced" section is a multi-line `Text` created with `SWT.WRAP`, and it is filled with `wProperties.setText(getProperties())` right after creation, while the control still has no size. The content includes `java.class.path`, which is one very long line without any whitespace (tens of thousands of characters when Hop is started from an IDE, still long with a regular install). On Windows the native Edit control recomputes the word wrapping of the whole text every time its width changes, and that is slow on such a line. After the text is set, the dialog is sized and laid out several times before it is shown: ```java shell.setSize(width, (int) (600 * zoom)); shell.layout(true, true); collapsedHeight = computeCollapsedHeight(margin); shell.setSize(width, collapsedHeight); ``` Each of these re-wraps the text, although the "Advanced" section is collapsed when the dialog opens. ### Verification Moving `wProperties.setText(getProperties())` after the `setSize` / `layout` calls (just before `shell.open()`) makes the dialog open instantly. ### Proposed fix - Set the properties text after the dialog has been sized (or only when the "Advanced" section is expanded for the first time). ### Steps to reproduce 1. Start Hop Gui on Windows (most visible when started from an IDE, where the classpath is very long). 2. Open Help > About. 3. The dialog appears after a visible delay. ### Issue Priority Priority: 3 ### Issue Component Component: Hop Gui -- This is an automated message from the Apache Git Service.
