基于选项卡隐藏和显示容器 windows
Hiding and showing container windows based on tab
我创建了一个包含两个选项卡的选项卡控件。在每个选项卡内将有一个容器 window 来容纳其他控件(在代码示例中,例如静态控件)。 The idea is that when a new tab is selected, it will hide/show the correct container window that holds a bunch of controls.但是,我正在努力让容器 windows 持有要显示的静态控件。这是到目前为止的代码:
#include <windows.h>
#include <commctrl.h>
#pragma comment(lib, "comctl32.lib")
#define ID_TABCTRL 1
#define ID_STATIC0 2
#define ID_STATIC1 3
#define ID_TAB0 4
#define ID_TAB1 5
LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);
HWND hTab, hTab0, hTab1;
int WINAPI wWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, PWSTR pCmdLine, int nCmdShow)
{
MSG msg;
WNDCLASS wc = { 0 };
wc.lpszClassName = TEXT("Tab control");
wc.hInstance = hInstance;
wc.hbrBackground = GetSysColorBrush(COLOR_3DFACE);
wc.lpfnWndProc = WndProc;
wc.hCursor = LoadCursor(0, IDC_ARROW);
RegisterClass(&wc);
CreateWindow(wc.lpszClassName, TEXT("Tab control"), WS_OVERLAPPEDWINDOW | WS_VISIBLE, 100, 100, 250, 200, 0, 0, hInstance, 0);
while (GetMessage(&msg, NULL, 0, 0))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
return (int)msg.wParam;
}
LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
TCITEM tie;
INITCOMMONCONTROLSEX icex;
switch (msg)
{
case WM_CREATE:
icex.dwSize = sizeof(INITCOMMONCONTROLSEX);
icex.dwICC = ICC_TAB_CLASSES;
InitCommonControlsEx(&icex);
tie.mask = TCIF_TEXT;
///// Create Tab Control /////
hTab = CreateWindow(WC_TABCONTROL, NULL, WS_CHILD | WS_VISIBLE, 0, 0, 200, 150, hwnd, (HMENU)ID_TABCTRL, NULL, NULL);
///// Create Individual Tabs /////
tie.pszText = TEXT("First");
SendMessage(hTab, TCM_INSERTITEM, 0, (LPARAM)(LPTCITEM)&tie);
tie.pszText = TEXT("Second");
SendMessage(hTab, TCM_INSERTITEM, 1, (LPARAM)(LPTCITEM)&tie);
///// Create Container windows for each tab /////
hTab0 = CreateWindow(0, NULL, WS_CHILD | WS_VISIBLE, 0, 0, 200, 150, hTab, (HMENU)ID_TAB0, NULL, NULL);
hTab1 = CreateWindow(0, NULL, WS_CHILD, 0, 0, 200, 150, hTab, (HMENU)ID_TAB1, NULL, NULL);
///// Add example control to one of the tab container windows /////
CreateWindow(TEXT("Static"), TEXT("Yay!"), WS_CHILD | WS_VISIBLE | SS_LEFT, 20, 30, 50, 25, hTab0, (HMENU)ID_STATIC0, NULL, NULL);
CreateWindow(TEXT("Static"), TEXT("It appears to be working"), WS_CHILD | WS_VISIBLE | SS_LEFT, 20, 30, 100, 50, hTab1, (HMENU)ID_STATIC1, NULL, NULL);
break;
case WM_NOTIFY:
switch (((LPNMHDR)lParam)->code)
{
case TCN_SELCHANGE:
switch (TabCtrl_GetCurSel(hTab))
{
///// Show or Hide the appropriate tabs /////
case 0:
ShowWindow(hTab1, SW_HIDE);
ShowWindow(hTab0, SW_SHOW);
case 1:
ShowWindow(hTab0, SW_HIDE);
ShowWindow(hTab1, SW_SHOW);
}
}
break;
case WM_DESTROY:
PostQuitMessage(0);
break;
}
return(DefWindowProc(hwnd, msg, wParam, lParam));
}
是否只是容器 windows hTab0 和 hTab1 卡在选项卡后面的情况 window (hTab)?
首先需要改变tab和静态表单的位置,否则会挡住生成的内容
那么可以直接通过CreateWindow
, by using WC_STATIC
定义生成的静态文本。

朱松的回答帮助解决了问题(容器windows需要是一个静态控件,并且需要定位在选项卡控件的space内,在可点击的选项卡下方)。
这是结果,交换了两个容器 window 创建行:
hTab0 = CreateWindow(TEXT("Static"), NULL, WS_CHILD | WS_VISIBLE, 1, 25, 197, 123, hTab, (HMENU)ID_TAB0, NULL, NULL);
hTab1 = CreateWindow(TEXT("Static"), NULL, WS_CHILD, 1, 25, 197, 123, hTab, (HMENU)ID_TAB1, NULL, NULL);
请注意容器 window 大小和位置如何足够小以刚好适合主选项卡控件 window(您可以将 WS_BORDER 添加到样式以查看它的确切位置适合)。
