Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Editor touch input is always double-click

UE4 is basically unusuable for me on a touch-screen laptop. It's double-clicking for every touch in the editor. Checkboxes instantly revert themselves when touched. File menus instantly close themselves when opened. Expanded sections instantly collapse themselves, etc.

I'm running UE4 version 4.17.1 and Win10. I've disabled Use Mouse for Touch, but the problem persists. That seems to be for running the game, while this issue is happening in the editor itself. Please let me know if you'd like any additional information.

Product Version: UE 4.17

Still present in 4.18. When touching a button, the press event is fired.

When the button is released, we receive 3 events: release (which is expected), then press again, then release again.

This occurs in editor or packaged builds, even when "Use mouse for touch" is disabled. We currently employ several workarounds to deal with this but they are becomingly increasingly complex and will not keep us from needing to use custom UI widgets or a custom engine build.

do you have show mouse cursor activated?

avatar image ZLogic Dec 18 '17 at 02:46 PM

That's for playing the game. This topic is for touch input while editing in the editor.

4.19.1 and this is still an issue!

This bug is still here, in 4.21.2, when in editor, and playing game, even without "Use mouse for touch", "show mouse" or not, still double-click....

Win Surface with Win10 build 1803

Has anyone come up with a solution?

I use the following AutoHotkey script as a stop-gap fix. Please note that it's quite an imperfect fix and takes some getting used to. It will mess with your click-dragging on one screen, and mess with your mouse-only clicks on the other. Hold down a modifier key to bypass this hotkey.

 #If WinActive("ahk_class UnrealWindow") || WinActive("ahk_class Notepad++")
 ;==Click fix for correct screen
 screenX0 := 0
 screenY0 := 0
 screenX1 := 1920
 screenY1 := 1080
 MouseGetPos, mousex, mousey
 if (((mousex >= screenX0) && (mousex <= screenX1)) && ((mousey >= screenY0) && (mousey <= screenY1)))

This is great but as you say imperfect. When selecting components do you also get the effect as if Shift key is pressed?

avatar image ZLogic Jan 26 '19 at 02:18 AM

Yes, I hold down ALT under those circumstances. It's a trade-off.

I have 4.19.2, and its an issue for me too. Anyone found an answer for this?

Edit: Nevermind, this solved the issue for me: "If you set ShowMouseCursor to false in Player Controller class defaults, event should fire only once."

This issue is with touchscreen performance in the editor itself, not in-game and not with the player or player controller.

avatar image darkZ Jan 25 '19 at 02:25 PM

Was a bug report ever created for this?
