さて、できるだけ少数のライブラリを追加して、win32を使っています。私のアプリケーションはsplitterbarsを使って複数の子ウィンドウに分かれており、メインウィンドウにツールバーとステータスバーを追加しました。今、子ウィンドウの1つにツールバーを追加しようとしていますが、WM_SIZEが発生するとすぐにボタンが消えます。これは、すべてメインウィンドウのWndProcで行われます。ここでは、子ウィンドウのツールバーを作成するコードは次のとおりです。子ウィンドウのツールバーは変わっています
case WM_SIZE :
{
GetClientRect(hwnd, &rect);
// Resize toolbar
SendMessage(toolMain, TB_AUTOSIZE, 0, 0);
SendMessage(toolRender, TB_AUTOSIZE, 0, 0);
SendMessage(statusMain, WM_SIZE, 0, 0);
GetWindowRect(toolMain, &toolrect);
GetWindowRect(statusMain, &statusrect);
toolHeight = toolrect.bottom - toolrect.top;
statusHeight = statusrect.bottom - statusrect.top;
windowHeight = rect.bottom - rect.top;
GetWindowRect(toolRender, &toolrect);
toolRendHeight = toolrect.bottom - toolrect.top;
//Make sure window isn't too small
if (rect.right < MINSIZE * 4)
{
rect.right = MINSIZE * 4;
forceresize = true;
}
if (windowHeight < toolHeight + statusHeight + toolRendHeight + (MINSIZE * 2))
{
rect.bottom = toolHeight + statusHeight + toolRendHeight + (MINSIZE * 2);
forceresize = true;
}
//resize splitters
xDiv1 = rect.right * xDiv1p;
xDiv2 = rect.right * xDiv2p;
xDiv3 = rect.right * xDiv3p;
yDiv = rect.bottom * yDivp;
// Make sure splitters aren't beyond bounds
if (xDiv3 > rect.right - MINSIZE)
xDiv3 = rect.right - MINSIZE;
else if(xDiv3 < xDiv2 + MINSIZE)
xDiv3 = xDiv2 + MINSIZE;
if (xDiv2 > xDiv3 - MINSIZE)
xDiv2 = xDiv3 - MINSIZE;
else if (xDiv3 < xDiv1 + MINSIZE)
xDiv2 = xDiv1 + MINSIZE;
if (xDiv1 > xDiv2 - MINSIZE)
xDiv1 = xDiv2 - MINSIZE;
else if (xDiv1 < MINSIZE)
xDiv1 = MINSIZE;
if (yDiv > rect.bottom - MINSIZE)
yDiv = rect.bottom - MINSIZE;
else if(yDiv < MINSIZE + toolrect.bottom)
yDiv = MINSIZE + toolrect.bottom;
// Resize windows
MoveWindow(wndObjBrowser, 0, toolHeight, xDiv1 - SBS, windowHeight - toolHeight - statusHeight, FALSE);
MoveWindow(wndObjList, xDiv1 + SBS, toolHeight, xDiv2 - xDiv1 - (SBS * 2), windowHeight - toolHeight - statusHeight, FALSE);
if (!bDualMonitor)
{
MoveWindow(wndRender, xDiv2 + SBS, toolHeight, rect.right - xDiv2 - SBS, yDiv - toolHeight - SBS, FALSE);
//SendMessage(toolRender, TB_AUTOSIZE, 0, 0);
MoveWindow(wndAreaList, xDiv2 + SBS, yDiv + SBS, xDiv3 - xDiv2 - (SBS * 2), windowHeight - statusHeight - yDiv - SBS, FALSE);
MoveWindow(wndAreaInfo, xDiv3 + SBS, yDiv + SBS, rect.right - xDiv3 - SBS, windowHeight - statusHeight - yDiv - SBS, FALSE);
}
else if (bDualMonitor)
{
MoveWindow(wndAreaList, xDiv2 + SBS, toolHeight, rect.right - xDiv2 - SBS, yDiv - toolHeight, FALSE);
MoveWindow(wndAreaInfo, xDiv2 + SBS, yDiv + SBS, rect.right - xDiv2 - SBS, windowHeight - statusHeight - yDiv - SBS, FALSE);
}
if (forceresize)
MoveWindow(hwnd, rect.left, rect.top, rect.right, rect.bottom, FALSE);
InvalidateRect(hwnd, &rect, TRUE);
}
break; //WM_SIZE
任意のアイデア：
toolRender = CreateWindowEx(0, TOOLBARCLASSNAME, NULL, WS_CHILD | WS_VISIBLE | TBSTYLE_TOOLTIPS,
0, 0, 0, 0, wndRender, NULL, gHinst, 0);
SendMessage(toolRender, TB_BUTTONSTRUCTSIZE, (WPARAM)sizeof(TBBUTTON), 0);
SendMessage(toolRender, CCM_SETVERSION, (WPARAM)5, 0);
himl = ImageList_LoadImage(NULL, L"buttons.bmp", 16, 2, RGB(0, 255, 255), IMAGE_BITMAP, LR_LOADFROMFILE | LR_CREATEDIBSECTION);
SendMessage(toolRender, TB_SETIMAGELIST, 0, (LPARAM)himl);
TBBUTTON tbb2[2];
memset(tbb2, 0, sizeof(tbb2));
tbb2[0].iBitmap = 0;
tbb2[0].fsState = TBSTATE_ENABLED;
tbb2[0].fsStyle = TBSTYLE_BUTTON;
tbb2[0].idCommand = TOOL_SAVEALL;
tbb2[0].iString = (INT_PTR)L"Save All";
tbb2[1].iBitmap = 1;
tbb2[1].fsState = TBSTATE_ENABLED;
tbb2[1].fsStyle = TBSTYLE_BUTTON;
tbb2[1].idCommand = TOOL_HELP;
tbb2[1].iString = (INT_PTR)L"Help";
SendMessage(toolRender, TB_SETMAXTEXTROWS, 0, 0);
SendMessage(toolRender, TB_ADDBUTTONS, sizeof(tbb2)/sizeof(TBBUTTON), (LPARAM)&tbb2);
そしてここでは、私の全体のWM_SIZEメッセージですか？
