This doesn't occur in 5.0.3 (the tree objects aren't draggable at all).
Likely caused by: commit 2fc1720781e8744c9df4a44cd943322889a55300 Author: Peifeng Yu <7437103@gmail.com> Date: Mon Sep 5 13:15:11 2016 -0400 Use GDB as default debugger backend
I just tested on the latest 5.1 branch. They are not draggable any more. IMO that makes sense because launches are associated with one project and there's no point to drag them around. Francis, can you reproduce this now?
Still draggable (and crashy) here with yesterday's kdevplatform/kdevelop 5.1-git. On Arch x86_64 with: kdevplatform v5.0.80-70-gd270016ad kdevelop v5.0.80-35-g2c1a1fd7f6 qt 5.8.0
Hmm, that's weird. I'm on Arch x86_64 too, with qt 5.8.0. And it works normally with today's 5.1 branch HEAD: kdevplatform: 3e2549d39 kdevelop: 2c1a1fd7f6 And in fact I can't find commit gd270016ad or g2c1a1fd7f6 in the repo... From your version string I guess you used makepkg to build & install? Is there anything special in the PKGBUILD? For sanity check, is there another different version of kdevelop in your system? And just in case, we are talking about the tree view in the "Launch Configurations" dialog which is opened when you click "Run -> Configure Launches...", right?
Created attachment 103945 [details] Dragging in launch dialog, causing a crash
`git describe` adds the leading 'g' for whatever reason; you must checkout either the full string ("v5.0.80-70-gd270016ad") or skip the 'g' ("d270016ad"). That's "Remove no longer needed spacer, now that we are a QFormLayout". I have no other versions installed and don't use makepkg, only `cmake`->`make`->`make install`. No local patches currently. I do have the [testing] repo enabled, but the bug's been there for at least a few weeks so the versions I had originally will be in stable by now. For exactly what I'm doing, see the attachment.
Oh I see. Didn't know much about git describe before. ;P Now I can finally reproduce the crash. Launcher items are in fact not draggable. But the crash happens when you click & hold the cursor, then move from a top-level item to its child item, e.g. Debug mode. And it only happens under the following condition: 1. The top-level item must have a child. (Compiled binary, Plasmoid launcher) 2. The child item must be a debug configuration with GDB selected. LLDB won't trigger the crash The crash happens because the code tries to set 'gdb' as launch configuration type on the wrong item. However this is before `LaunchConfiguration::launcherForMode` got called. I don't know how the 'gdb' type string was generated yet. I'm still tracing down the logic when changing pages in the dialog. Will report back with more info later.
Francis could you try https://phabricator.kde.org/D4555 and see if it works for you?
