We assume that `char` is `signed` in various places in the code. In particular, the `Str.StrToInts` test will fail when `char` is not `signed` and names containing special characters will be displayed incorrectly on servers.
Therefore, the compiler flag `-fsigned-char` is set unconditionally instead of only for ARM and ARM64, as we expect `char` to be `signed` on all architectures.
A static assertion is added to ensure at compile time that `char` is `signed` independently from the flag added in `CMakeLists.txt`.
This is necessary at least for ARM, ARM64, PPC, PPC64, and PPC64LE. According to some sources, `char` may also be `unsigned` by default when compiling for Android, although this could not be confirmed with the current Android NDK using Clang.
For the PowerPC architectures, Compiler Explorer can be used to confirm that `char` is not `signed` by default by checking whether the static assertion compiles (see https://godbolt.org/z/9rn5Mrf59) and that the assembly is different with the `-fsigned-char` flag (see https://godbolt.org/z/138zTj3Wa).
Closes#8386.
Fix button logic being stuck when holding mouse button on UI elements with button logic in the menus/editor, switching between menus and editor with Ctrl+Shift+E, then using a UI element with button logic in the editor/menus and switching back.
Fix value selector text mode of color picker popups being deactivated when switching between menus and editor while the color picker popup is open in both.
Only update progress spinners once per frame in `CUi::Update` to ensure consistent rotation speed. Progress spinners in menus and editor now rotate independently.
In general, all `static` non-`const` variables in `CUi` are replaced with member variables, as the `static` variables are shared between the two `CUi` instances of the menus and the editor, causing the above issues.
The percentage of received console commands was not being shown with the progress spinner because the variable `ProgressProps` was not passed to the `RenderProgressSpinner` function.
Replace the last remaining usage of the `CUi::MouseButtonReleased` function with `!MouseButton(...)`. The `pMouseSelection->m_Selecting` flag is only set to `true` when the mouse button is already pressed down, so the additional check of `MouseButtonReleased` is unnecessary in this case. In general, this function is an anti-pattern in our UI, as only checking for the mouse button to be released does not guarantee that the mouse was also pressed down over the respective UI element. The `DoButtonLogic` function or similar code should be used instead of only handling the press or release of a mouse button.
Make value selector behavior consistent with the generic button logic. Consistently check for completed mouse clicks on the value selector UI element instead of handling some mouse down and mouse up events separately. Fix text mode being activated when moving the mouse over value selectors with held down mouse button. Fix text mode being deactivated immediately when the mouse leaves text area while holding down the mouse button, which is inconvenient when selecting text. Remove unnecessary usage of `CUi::MouseButtonReleased` function.
Support double-clicking value selectors to enter text edit mode in addition to right-clicking. This feels more intuitive to use and also makes it usable without a second mouse button.
Select all text when entering text mode also in the editor, which was previously only a feature in the menus.
Fix value selector edit state being `EDITING` by default instead of `NONE` in the editor and fix maps being marked as modified immediately when a value selector text input is activated. The map will now be marked as modified only when the editing operation is completed, which should be synchonized with the undo history action being added.
Use the `CUi::ConsumeHotkey` function instead of checking the enter keys manually.
Remove unnecessary and unused `CUi::m_ValueSelectorTextMode` variable and its accessors as well as the equivalent `s_TextMode` variable in the editor. This separate flag is unnecessary as we can use the existing `s_pLastTextId` variable instead.
