SUMMARY The "Add/Subtract/Multiply/Divide Value" functions for matrix are completely unusable. Attempting to use the functions will result in a "Wrong numeric value provided" error. Enabling the "Preview" feature will make LabPlot crash. STEPS TO REPRODUCE 1. Launch LabPlot and create a new project 2. Add a matrix to the project (the default 10×10 zero matrix is OK) 3. Go to "Matrix → Manipulate Data → Add/Subtract/Multiply/Divide Value" 4a. Either click the "Add/Subtract/Multiply/Divide" button (the default value 0 is OK) 4b. Or enable the "Preview" checkbox for Add and Subtract OBSERVED RESULT 4a: A "Wrong numeric value provided" error occurs 4b: LabPlot crashes EXPECTED RESULT No error or crash should happen SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.1.5 KDE Frameworks Version: 6.6.0 Qt Version: 6.7.2 Kernel Version: 6.10.10-arch1-1 (64-bit) Graphics Platform: Wayland ADDITIONAL INFORMATION Backtrace for the crash (some debuginfod symbol packs are not downloaded): #0 AddSubtractValueDialog::initPreview (this=0x555556cf8d60) at /usr/src/debug/labplot/labplot-2.11.1/src/kdefrontend/spreadsheet/AddSubtractValueDialog.cpp:527 #1 0x0000555555944e58 in AddSubtractValueDialog::updatePreview (this=0x555556cf8d60) at /usr/src/debug/labplot/labplot-2.11.1/src/kdefrontend/spreadsheet/AddSubtractValueDialog.cpp:575 #2 0x0000555555933d2a in AddSubtractValueDialog::previewChanged (this=0x555556cf8d60, state=<optimized out>) at /usr/src/debug/labplot/labplot-2.11.1/src/kdefrontend/spreadsheet/AddSubtractValueDialog.cpp:446 #3 0x00007ffff4ce35de in ??

Git commit 67391b1853a22454cb136e22b6617300613c4614 by Alexander Semke. Committed on 28/09/2024 at 09:32. Pushed by asemke into branch 'master'. Adressed multiple issues in the "add/subtract values" dialog introduced with the last new features in this area - baseline subtractions, preview of the results and working with differences: * hide the preview option for Matrix, not supported yet, needs to be done differently than for the Spreadsheet * properly initialize the start and end values if add/subtract is done based on the difference of values * properly add/subtract values instead of showing "wrong value provided" FIXED-IN: 2.12 M +1 -0 ChangeLog M +2 -2 src/commonfrontend/matrix/MatrixView.cpp M +88 -53 src/kdefrontend/spreadsheet/AddSubtractValueDialog.cpp M +2 -1 src/kdefrontend/spreadsheet/AddSubtractValueDialog.h https://invent.kde.org/education/labplot/-/commit/67391b1853a22454cb136e22b6617300613c4614
