QML VirtualKeyboard错误，以输入网站的字符 [英] QML VirtualKeyboard error to enter character to a website

问题描述

我目前正在修复目录系统上的一些错误。

这个系统有一个Webview面板和一个虚拟键盘。

这个系统是用QML，Javascript开发的和1％的C ++。

虚拟键盘在代码中有错误。 我输入了小写字母a，在网站文本框中它将显示为大写A。这发生在从A到Z的所有角色。



另一个问题是当我进入符号时，会出现奇怪的角色在文本框中。



以下来自事件面板的来源 QML 文件。

I currently repairing some bugs on the Directory System.
This system has a Webview panel and also a virtual keyboard.
This system was developed by using QML, Javascript and 1% of C++.
The virtual keyboard has error in the codes. I entered lower case ''a'',in the website textbox it will appear as upper-case''A''. And this happen to all the character from A to Z.

And another problem is when I entered Symbols, there will be weird character appearing in the textbox.

Here below source from Event Panel QML file.

//------------------------------------------------------
//                    Keyboard
//------------------------------------------------------

WebKeyboardPad
{
    id: keyboard
    x: 0
    y: event_panel.height + keyboard.height;
    anchors.horizontalCenter: parent.horizontalCenter
    onClicked: Globals.onKeyboardClicked(tag);
    onBackspace: Globals.onKeyboardBackspace();
    opacity: 1

    Behavior on y
    {
        id: behavior_nb_keyboard_y
        enabled: keyboard.isDragging
        NumberAnimation { duration: 300; }
    }
    Behavior on opacity
    {
        NumberAnimation { duration: 300; }
    }
}

此来源来自 JavaScript 文件;

This source is from a JavaScript file;

function onKeyboardClicked(keyName)
{
    home_main.onKeyboardClicked(keyName);
}

function onKeyboardBackspace()
{
    home_main.onKeyboardClicked("backspace");
}

来自Main QML 文件

This from Main QML file

//---------------------------------------------------
   // Custom plugins
   //---------------------------------------------------

   HardwareInfo
   {
       id: syshardware
   }

   function onKeyboardClicked(Keys)
   {
       myKeyboard.simulateKey(Keys);        //Injected in main.cpp
   }

   function onKeyboardBackspace(KeyNavigation)
   {
       myKeyboard.simulateKey(KeyNavigation);        //Injected in main.cpp
       //search_box.backspaceKey();
   }

这里最后一个是C ++文件



keyboard.cpp



我更改了 keyboard.cpp 文件，但是当我尝试更改c ++代码时，结果仍然相同。

Here the last one is the C++ file

keyboard.cpp

I got change the keyboard.cpp file but when I try which the c++ code change, the result still the same.

I have change the cpp file but it still does not work.
Hopefully someone can help me to solve this problem.
Thank you
