Re: SplitPane layout question
Hi Scott, Thanks for your answer. Unfortunatly, I still couldn't fix this issue. I tried several things including setting the prefWidth/ prefHeight of the items to the expected value, but I couldn't stop the SplitPane to effectively hide the first and the third (last) item during a re-layout. The two dividers changed during the layoutChildren call as follows: Divider position changed: old value: 0.10857763300760044, new value: 0.004343105320304018 Divider position changed: old value: 0.8914223669923995, new value: 0.995656894679696 I had a look at the com.sun.javafx.scene.control.skin.SplitPaneSkin (source code provided with the JDK), but unfortunatly it's not easy there to see how the areas are calculated in this situation. You mentioned the min/ max sizes. Just for testing purposes I also set the minHeight/ minWidth but this only had the effect that I couldn't readjust the divider with the mouse anymore. During the re-layout the issue still persisted. What else could I try? -Florian Am Montag, 22.
