Feel free to query i - input text: add discard flag (e.g. ImGuiInputTextFlags_DiscardActiveBuffer) or make it easier to clear active focus for text replacement during edition (#725) - input text: display bug when clicking a drag/slider after an input text in a different window has all-selected text (order dependant). actually a very old bug but no one appears to have noticed it. - input text multi-line: don't directly call AddText() which does an unnecessary vertex reserve for character count prior to clipping. and/or more line-based clipping to AddText(). and/or reorganize TextUnformatted/RenderText for more efficiency for large text (e.g TextUnformatted could clip and log separately, etc). + - input text multi-line: support for cut/paste without selection (cut/paste the current line) - input text multi-line: line numbers? status bar? (follow up on #200) - input text multi-line: behave better when user changes input buffer while editing is active (even though it is illegal behavior). namely, the change of buffer can create a scrollbar glitch (#725) - input text multi-line: better horizontal scrolling support (#383, #1224) diff --git a/imgui.cpp b/imgui.cpp index b7057412..1f3afb5d 100644 --- a/imgui.cpp +++ b/imgui.cpp @@ -8610,6 +8610,10 @@ bool ImGui::InputTextEx(const char* label, char* buf, int buf_size, const ImVec2 const bool is_wordmove_key_down = io.OptMacOSXBehaviors ? io.KeyAlt : io.KeyCtrl; // OS X style: Text editing cursor movement using Alt instead of Ctrl const bool is_startend_key_down = io.OptMacOSXBehaviors && io.KeySuper && !io.KeyCtrl && !io.KeyAlt; // OS X style: Line/Text Start and End using Cmd+Arrows instead of Home/End + const bool is_paste = (is_shortcut_key_only && IsKeyPressedMap(ImGuiKey_V)) && is_editable; + const bool is_cut = (is_shortcut_key_only && IsKeyPressedMap(ImGuiKey_X)) && is_editable && !is_password && (!is_multiline || edit_state.HasSelection()); + const bool is_copy = (is_shortcut_key_only && IsKeyPressedMap(ImGuiKey_C)) && !is_password && (!is_multiline || edit_state.HasSelection()); + if (IsKeyPressedMap(ImGuiKey_LeftArrow)) { edit_state.OnKeyPressed((is_startend_key_down ?
