Ax and touch screen

[ist]

Hi, Guys

I have a form similar to(see attachment). User will interact with the form through touch screen without keyboard and mouse. How can I simulate a keypress when the user touches the button on the form?

Touching is a mouse click. You have a different?

Hi!
I think you can use your mouse, if you'll click on buttons in your form in Dynamics you can simulate and debug your action. The method which called when users press buttons on your form is "clicked" independent of the way of pressing

I know but, I have another idea: to use the task method on the form and for example if the user touches button 7, in the click method to do:

void clicked()
{
    super();
 
    ctrl_InputQuantity.setFokus();
    element.task(#Key7); // simulate key 7 pressed
}

My goal is: when the ctrl_InputQuantity is in focus, I hope that it could catches keypress 7

ist, Hi!

Your idea is good, but i think you can't simulate button click by this method. You can try to place breakpoint in task() method in your form like this:

public int task(int _taskId)
{
    int ret;
    ;
    ret = super(_taskId);
    breakpoint;
    return ret;
}

In this example when i clicked by mouse on buttons form (left clicked), i can't step in this method in debugger. But if i'll use keyboard, system should step in with _taskId parameter.

You can use WinAPI:

#WinAPI
#KeyPressed
void clicked()
{
    super();

    ctrl_InputQuantity.setFocus();
    ctrl_InputQuantity.setSelection(-1,0);
    WinAPI::postMessage(ctrl_InputQuantity.hWnd(), #WM_KEYDOWN, #Key7, 0);
}

You can use WinAPI:

#WinAPI
#KeyPressed
void clicked()
{
    super();
 
    ctrl_InputQuantity.setFocus();
    ctrl_InputQuantity.setSelection(-1,0);
    WinAPI::postMessage(ctrl_InputQuantity.hWnd(), #WM_KEYDOWN, #Key7, 0);
}

Thanks a lot, it works perfect. The bad news is thah in the #KeyPressed I didn't found comma macro. I have noticed that some macroses coincides with ASCII code of the characters. I try with ASCII code 44 that is ASCII code of the comma character, but without success.

WinAPI::postMessage(ctrlQty.hWnd(), #WM_KEYDOWN, #Comma, 0);

I believe WM_KEYDOWN message's wParam parameter is a virtual-key code, not an ASCII-code. VK_OEM_COMMA value is 0xBC.
