From 3d0a9b2becd6a51c17b639c0feb861be205e598b Mon Sep 17 00:00:00 2001 From: Dave Palais Date: Sun, 30 Oct 2022 12:50:27 -0500 Subject: Remove the usage of pointers in signal call, to fix #67941 The signal was emitted right as the node was being disposed of. Since the connection was deferred, the receiving method received an already freed pointer. Instead, we listen to the text_changed signal and keep record of the edited text which we then use to update node name when the LineEdit goes out of focus. --- editor/plugins/animation_blend_tree_editor_plugin.cpp | 14 ++++++++++---- editor/plugins/animation_blend_tree_editor_plugin.h | 4 +++- 2 files changed, 13 insertions(+), 5 deletions(-) (limited to 'editor/plugins') diff --git a/editor/plugins/animation_blend_tree_editor_plugin.cpp b/editor/plugins/animation_blend_tree_editor_plugin.cpp index 067730a87a..dd83716759 100644 --- a/editor/plugins/animation_blend_tree_editor_plugin.cpp +++ b/editor/plugins/animation_blend_tree_editor_plugin.cpp @@ -153,7 +153,8 @@ void AnimationNodeBlendTreeEditor::update_graph() { node->add_child(name); node->set_slot(0, false, 0, Color(), true, read_only ? -1 : 0, get_theme_color(SNAME("font_color"), SNAME("Label"))); name->connect("text_submitted", callable_mp(this, &AnimationNodeBlendTreeEditor::_node_renamed).bind(agnode), CONNECT_DEFERRED); - name->connect("focus_exited", callable_mp(this, &AnimationNodeBlendTreeEditor::_node_renamed_focus_out).bind(name, agnode), CONNECT_DEFERRED); + name->connect("focus_exited", callable_mp(this, &AnimationNodeBlendTreeEditor::_node_renamed_focus_out).bind(agnode), CONNECT_DEFERRED); + name->connect("text_changed", callable_mp(this, &AnimationNodeBlendTreeEditor::_node_rename_lineedit_changed), CONNECT_DEFERRED); base = 1; node->set_show_close_button(true); node->connect("close_request", callable_mp(this, &AnimationNodeBlendTreeEditor::_delete_request).bind(E), CONNECT_DEFERRED); @@ -991,13 +992,18 @@ void AnimationNodeBlendTreeEditor::_node_renamed(const String &p_text, Ref p_node) { - if (le == nullptr) { +void AnimationNodeBlendTreeEditor::_node_renamed_focus_out(Ref p_node) { + if (current_node_rename_text.is_empty()) { return; // The text_submitted signal triggered the graph update and freed the LineEdit. } - _node_renamed(le->call("get_text"), p_node); + _node_renamed(current_node_rename_text, p_node); +} + +void AnimationNodeBlendTreeEditor::_node_rename_lineedit_changed(const String &p_text) { + current_node_rename_text = p_text; } bool AnimationNodeBlendTreeEditor::can_edit(const Ref &p_node) { diff --git a/editor/plugins/animation_blend_tree_editor_plugin.h b/editor/plugins/animation_blend_tree_editor_plugin.h index 46e0d18c69..b55fc3b617 100644 --- a/editor/plugins/animation_blend_tree_editor_plugin.h +++ b/editor/plugins/animation_blend_tree_editor_plugin.h @@ -92,9 +92,11 @@ class AnimationNodeBlendTreeEditor : public AnimationTreeNodeEditorPlugin { void _node_dragged(const Vector2 &p_from, const Vector2 &p_to, const StringName &p_which); void _node_renamed(const String &p_text, Ref p_node); - void _node_renamed_focus_out(Node *le, Ref p_node); + void _node_renamed_focus_out(Ref p_node); + void _node_rename_lineedit_changed(const String &p_text); void _node_changed(const StringName &p_node_name); + String current_node_rename_text; bool updating; void _connection_request(const String &p_from, int p_from_index, const String &p_to, int p_to_index); -- cgit v1.2.3
