MOUSE COORDINATES WINDOWS 10 KEYGEN
I was telling the engine the visible image potion using uv coordinates, i calculate them myself, these are the same data you recieve when rendering an image using gl_handle, the same data you recive from imgui, the UV coodinates, and i am using them to calculate the click coordinates relative to the inner world of the engine, i pass them to the engine using EngineInbox.SetViewPortion(uv1.x,uv1.y,uv2.x,uv2. My mistake was that i tried to calculate the screen cursor position myself using cursor position relative to window + imgui window position relative to sdl window and i got slightly wrong results, now i am using 'GetCursorScreenPos()'Īnd about this : EngineInbox.SetViewPortion(uv1.x,uv1.y,uv2.x,uv2.y) It is complicated because i want the black poriton ( engine screen ) to be with scrolling, and i want the user to be able to resize the window and scroll it to navigate through the engine's screen, and when he clicks, whereever the scrolling is, i still calculate the currect coordinates relative to the internal engine world, in other words, the coordinates of the click relative to the top left corner of the drawn image ( the engine screen ) and that with scrollling included. Then i pass the click to the engine, now i am getting wrong results of about 2 to 12 pixels deppending on the position of the horizontal and virtical scroll bar of the back portion, then what i do is to hide the cursor and ask the engine to draw it when the cursor passes through it. If (mx>=rendering_x & my>=rendering_y & mxGetWidth() įmy = (float(my)-rendering_y)+uv1_y*Umb::Graphics::GetDisplay()->GetHeight() Įvent->SetCoord(mx,my) /// transform click relative to black portion UmbPointerMoveEvent * event = dynamic_cast(update_frame->event)
If (update_frame->event->GetType() = UmbEventType::POINTER_MOVE) Uv2.x = ImGui::GetContentRegionAvail().x / engine_screen->w +uv1.x ĮngineInbox.SetViewPortion(uv1.x,uv1.y,uv2.x,uv2.y) Uv1.y = abs(ImGui::GetWindowContentRegionMin().y)/engine_screen->h Uv1.x = abs(ImGui::GetWindowContentRegionMin().x)/engine_screen->w Under the General tab, in the Hotkeys section, set your hotkeys.You've five options to set hotkeys for. Click on the Greenshot logo and then select Preferences. Now to take screenshots efficiently in Greenshot, it's best to set some hotkeys beforehand. ImVec2 uv1,uv2 /// top left and button down range ( 0. In the Capture tab, check the Capture mouse pointer option. / tell the engine the current view potion ImGui::Image((ImTextureID)GPU_GetImageHandle(engine_screen->image),ImVec2(engine_screen->w,engine_screen->h)) ImVec2 w_pos = ImGui::GetCursorPos() ,c_pos = ImGui::GetWindowPos() ĮngineInbox.SetRenderingPosition(w_pos.x+c_pos.x,w_pos.y+c_pos.y) / tell the engine the current draw position ImVec2 win_region = ImGui::GetContentRegionAvail() ĮngineInbox.SetRenderingWindowSize(win_region.x,win_region.y) The tool also provides information about the DPI scaling and the raw/ physical DPI of the current monitor. / move the draw cursor to the top left corner of the window The tracked cursor position is provided in physical/ unscaled Windows pixels and in coordinates scaled by DPI-virtualization. / tell the inbox if it should receive inputĮngineInbox.SetInputOn(ImGui::GetWindowIsFocused())
