Hi, folks: I developed an IDEA plugin, but during the compatibility verification before publishing, it was flagged for using an [internal API](https://github.com/JetBrains/intellij-community/commit/55a5cc91f5d13eb0df2cd12d74c677b9b6a2f6c6). I used the class **DocumentFragmentTooltipRenderer** , which has now been marked as an internal API, to display tooltips. I initially attempted to replace it with the following code: ```java DocumentFragment range = createDocumentFragment(editorEx, region); HintManager.getInstance().showInformationHint(editorEx, editorEx.getDocument().getText(range.getTextRange())); ``` However, the tooltip no longer displays syntax highlighting as it originally did: ![expected_actual](https://us1.discourse-cdn.com/flex001/uploads/jetbrains_platform/original/1X/e6c802d386298cec851c97d008d03e4ef309b324.png) Any suggestions would be greatly appreciated. ---

Additionally, I have created [this issue](https://youtrack.jetbrains.com/issue/MP-7255/DocumentFragmentTooltipRenderer-was-marked-as-internal) in the issue tracker. ---

Thanks for highlighting, discussion should continue in the created issue. ---

Hello @yann.cebron, Regarding the previously mentioned plugin, to be precise, I have forked an outdated plugin. It creates custom `FoldRegion`s and uses ```java TooltipController.getInstance().showTooltip( editor, point, new DocumentFragmentTooltipRenderer(documentFragment), false, FOLDING_TOOLTIP_GROUP ); ``` to display the original text of the folded region. The effect is similar to: ![showTooltip](https://us1.discourse-cdn.com/flex001/uploads/jetbrains_platform/original/1X/fbbd3f665432d1c1408941bf14549a3c1c5ef777.png) Since `DocumentFragmentTooltipRenderer` has been marked as an internal API, I would like to replace it with an alternative method, such as `HintManager.getInstance().showInformationHint` However, I noticed that other custom `FoldRegion`s automatically display the original folded text when the mouse moves, **even without using `showTooltip`**. How can I programmatically disable the automatic display of folded text for FoldRegion? ---

Because I found that only this specific FOLDREGION requires calling `DocumentFragmentTooltipRenderer` manually to display the folded text when the mouse is moved, while other regions can display the folded text automatically, I wanted to disable the automatic display for all regions and use an alternative method to show it manually. Actually, I don’t quite understand when IDEA automatically displays the original text of a FoldRegion… ---

You can specify the placeholder text when building the fold region, not sure why there would be any need for anything else. This behaviour with showing placeholder text (or `...` if not specified) is consistent within the platform and should not be overridden by plugins. ---

@yann.cebron Thanks for the tip! I changed the placeholder text from an empty string to a zero-width space, so now even hidden FoldRegions will show the tooltip text when hovered over with the mouse.
