  1. POSize of button in a toolbar - win32 program
    text
    copied!<p>I am creating toolbar with my bitmap images, and I have problem with the button size.<br> this image size is 20/20 pixels. </p> <p><img src="https://i.stack.imgur.com/DA5t6.png" alt="enter image description here"></p> <p>and I create a toolbar, and set the button size to 20/20 pixels, by this code: </p> <pre><code>SendMessage(hToolbar, TB_SETBUTTONSIZE, 0, MAKELPARAM(20, 20)); </code></pre> <p>and I set the color scheme to red and green, so the button frame will display clearly when the cursor standing over the button. </p> <p>and this what I see when cursor standing over the button: </p> <p><img src="https://i.stack.imgur.com/3X6JE.jpg" alt="enter image description here"></p> <p>As you can see the button size is not 20 \ 20 pixels, but 26 pixels. so why it happened? </p> <p>And one more question, is it possible to cancel the highlighting button when the mouse cursor is over it, and instead I will set hot image list (by <code>TB_SETHOTIMAGELIST</code> message), so when the cursor will stand over the button, the hot image will display, without highlighting the button. </p> <p>and this is the full code: </p> <pre><code>#include &lt;windows.h&gt; #include &lt;stdlib.h&gt; #include &lt;CommCtrl.h&gt; #pragma comment(lib, "comctl32.lib") #define IDB_PRINT 40000 LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM); HINSTANCE instance; int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) { instance = hInstance; WNDCLASSEX wcex; wcex.cbSize = sizeof(WNDCLASSEX); wcex.style = CS_HREDRAW | CS_VREDRAW; wcex.lpfnWndProc = WndProc; wcex.cbClsExtra = 0; wcex.cbWndExtra = 0; wcex.hInstance = hInstance; wcex.hIcon = LoadIcon(hInstance, MAKEINTRESOURCE(IDI_APPLICATION)); wcex.hCursor = LoadCursor(NULL, IDC_ARROW); wcex.hbrBackground = (HBRUSH)(COLOR_WINDOW+1); wcex.lpszMenuName = NULL; wcex.lpszClassName = L"Example"; wcex.hIconSm = LoadIcon(wcex.hInstance, MAKEINTRESOURCE(IDI_APPLICATION)); RegisterClassEx(&amp;wcex); HWND hWnd = CreateWindow(L"Example", L"", WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, CW_USEDEFAULT, 500, 500, NULL, NULL, hInstance, NULL); // Initialize common controls.
