复选框(选中或未选中) [英] Checkbox (checked or unchecked)

问题描述

在使用自动化客户端时，我正在遍历窗口的所有元素.

我想要按钮...

这是代码...

<预><代码>

如何在不运行其他 UI 的情况下获取这 3 个属性值中的任何一个.

解决方案

这里是一些示例代码，如果运行 Discord，将打印Mute"按钮状态:

#include #include #include #include #include int main(){//警告:省略错误检查！CoInitializeEx(NULL, COINITBASE_MULTITHREADED);{//启动 UIA &获得root权限CComPtr<IUIAutomation>自动化;自动化.CoCreateInstance(CLSID_CUIAutomation8);CComPtr根;自动化->GetRootElement(&root);//找到Discord"窗户CComPtr不和谐；自动化-> CreatePropertyCondition(UIA_NamePropertyId, CComVariant(LDiscord"), &discordCondition);CComPtr不和谐;root-> FindFirst(TreeScope_Children, discordCondition, &discord);//创建一个名称=静音"&&类型 = 按钮条件CComPtr静音状态；自动化-> CreatePropertyCondition(UIA_NamePropertyId, CComVariant(LMute"), &muteCondition);CComPtr按钮状态；自动化-> CreatePropertyCondition(UIA_ControlTypePropertyId, CComVariant(UIA_ButtonControlTypeId), &buttonCondition);CComPtr和条件；自动化-> CreateAndCondition(muteCondition, buttonCondition, &andCondition);//获取静音"按钮CComPtr静音按钮;不和谐-> FindFirst(TreeScope_Subtree, andCondition, &muteButton);//获取切换模式CComPtr切换;muteButton->GetCurrentPatternAs(UIA_TogglePatternId, IID_PPV_ARGS(&toggle));//获取切换状态ToggleState 状态；切换->get_CurrentToggleState(&state);开关(状态){案例 ToggleState_Off:wprintf(L状态关闭.\n");休息;案例 ToggleState_On:wprintf(L"state is on.\n");休息;案例 ToggleState_Indeterminate:wprintf(L"state is indeterminate.\n");休息;}}CoUninitialize();}

While using automation client I am iterating over all the elements of the window.

And I want to get button...

Here is code...

How can I get any of these 3 property values without running through another UI.

解决方案

Here is some sample code which, if Discord is ran, will print the "Mute" button state:

#include <windows.h>
#include <atlbase.h>
#include <atlcom.h>
#include <UIAutomationCore.h>
#include <UIAutomationClient.h>

int main()
{
    // warning: error checks omitted!
    CoInitializeEx(NULL, COINITBASE_MULTITHREADED);
    {
        // start UIA & get root
        CComPtr<IUIAutomation> automation;
        automation.CoCreateInstance(CLSID_CUIAutomation8);

        CComPtr<IUIAutomationElement> root;
        automation->GetRootElement(&root);

        // find the "Discord" window
        CComPtr<IUIAutomationCondition> discordCondition;
        automation->CreatePropertyCondition(UIA_NamePropertyId, CComVariant(L"Discord"), &discordCondition);

        CComPtr<IUIAutomationElement> discord;
        root->FindFirst(TreeScope_Children, discordCondition, &discord);

        // create a name="Mute" && type = button condition
        CComPtr<IUIAutomationCondition> muteCondition;
        automation->CreatePropertyCondition(UIA_NamePropertyId, CComVariant(L"Mute"), &muteCondition);

        CComPtr<IUIAutomationCondition> buttonCondition;
        automation->CreatePropertyCondition(UIA_ControlTypePropertyId, CComVariant(UIA_ButtonControlTypeId), &buttonCondition);

        CComPtr<IUIAutomationCondition> andCondition;
        automation->CreateAndCondition(muteCondition, buttonCondition, &andCondition);

        // get "Mute" button
        CComPtr<IUIAutomationElement> muteButton;
        discord->FindFirst(TreeScope_Subtree, andCondition, &muteButton);

        // get toggle pattern
        CComPtr<IUIAutomationTogglePattern> toggle;
        muteButton->GetCurrentPatternAs(UIA_TogglePatternId, IID_PPV_ARGS(&toggle));

        // get toggle state
        ToggleState state;
        toggle->get_CurrentToggleState(&state);

        switch (state)
        {
        case ToggleState_Off:
            wprintf(L"state is off.\n");
            break;

        case ToggleState_On:
            wprintf(L"state is on.\n");
            break;

        case ToggleState_Indeterminate:
            wprintf(L"state is indeterminate.\n");
            break;
        }
    }
    CoUninitialize();
}
