получить поведение кнопки (hovered/active) mimgui.

.026-beta

Возник вопрос, как получить поведение кнопки в mimgui, то есть, наведен ли курсор на кнопку? или же на кнопку нажали? Если в плюсах это намного проще, то как в mimgui?

bool hovered, held;
bool pressed = ImGui::ButtonBehavior(bb, id, &hovered, &held, 0);

 

[#Northn]

здесь такой функции нет, но можно вручную смастерить через IsItemHovered, IsItemActive

bool hovered, held;

_Bool                igIsItemHovered(ImGuiHoveredFlags flags);
_Bool                igIsItemActive(void);

Значит шобы отследить наведение или клик то

imgui.Button("Nigaa")
if imgui.IsItemHovered() then
    print("Ты навел курсор на кнопку")
end

а если надо чтобы засчитывало клик по области "bb"?

IMGUI_API bool          IsMouseHoveringRect(const ImVec2& r_min, const ImVec2& r_max, bool clip = true);// is mouse hovering given bounding rect (in screen space). clipped by current clipping settings, but disregarding of other consideration of focus/window ordering/popup-block.

ндааа, я даже не знаю как задать "bb" значение Min, и Max, да и думаю что плюсовых возможностей имгуи нету в мимгуи, приходится делать еще кучу лишних пальцедвижений для того чтобы сделать просто свой элемент гуи

эти методы следует использовать, как правило, при ручном рендере через примитивы, а в твоём случае, если хочешь сделать проверку на нажатие по тексту (это же по тексту?) достаточно использовать обычные функции:

// Item/Widgets Utilities and Query Functions // - Most of the functions are referring to the previous Item that has been submitted. // - See Demo Window under "Widgets->Querying Status" for an interactive visualization of most of those functions.
IMGUI_API bool IsItemHovered(ImGuiHoveredFlags flags = 0); // is the last item hovered? (and usable, aka not blocked by a popup, etc.). See ImGuiHoveredFlags for more options.
IMGUI_API bool IsItemActive(); // is the last item active? (e.g. button being held, text field being edited. This will continuously return true while holding mouse button on an item. Items that don't interact will always return false)
IMGUI_API bool IsItemFocused(); // is the last item focused for keyboard/gamepad navigation?
IMGUI_API bool IsItemClicked(ImGuiMouseButton mouse_button = 0); // is the last item hovered and mouse clicked on? (**) == IsMouseClicked(mouse_button) && IsItemHovered()Important. (**) this it NOT equivalent to the behavior of e.g. Button(). Read comments in function definition.
IMGUI_API bool IsItemVisible(); // is the last item visible? (items may be out of sight because of clipping/scrolling)
IMGUI_API bool IsItemEdited(); // did the last item modify its underlying value this frame? or was pressed? This is generally the same as the "bool" return value of many widgets.
IMGUI_API bool IsItemActivated(); // was the last item just made active (item was previously inactive).
IMGUI_API bool IsItemDeactivated(); // was the last item just made inactive (item was previously active). Useful for Undo/Redo patterns with widgets that requires continuous editing.
IMGUI_API bool IsItemDeactivatedAfterEdit(); // was the last item just made inactive and made a value change when it was active? (e.g. Slider/Drag moved). Useful for Undo/Redo patterns with widgets that requires continuous editing. Note that you may get false positives (some widgets such as Combo()/ListBox()/Selectable() will return true even when clicking an already selected item).
IMGUI_API bool IsItemToggledOpen(); // was the last item open state toggled? set by TreeNode().

не понятные вещи мне я подсветил, bb - это скорее рект по которому надо зафиксировать нажатие функциями ранее тобою написанных (IsMouseHoveringRect и IsMouseClicked) но тут лично мне не понятно как этот рект создать собственно
