Can't reconfigure the hotkeys for the control buttons.

[AlexSV]

Hello Tom!

I'm trying to configure the jog and step buttons in the Screen Editor so that pressing the arrow, page up/down, +, - keys on the keyboard would trigger the step mode, and their combination with the CTRL key would trigger the run mode, which is the opposite of how it's done by default. I can't change it. Is there a way to configure this?

Hi Alex,

That functionality is hard coded. To change that behaviour you would need to modify the function:

Code: Select all

int DoCheckShiftAndKey(int Key,WPARAM wParam, LPARAM lParam, CMotionButton &Button, CMotionButton &Button2, CMotionButton &ButtonStep)

Then re-compile KMotionCNC.

3 Screen buttons act in a group that share the same hotkey. That function decides based on the shift and control states which buttons to press or release.

Where is this function located? Does it require Visual Studio ?

[TomKerekes]

You can locate it by doing a find-in-files search such as the one in Visual Studio.

Yes you would need Visual Studio 2022

I adjusted the function, everything seems to work.
Thanks!

Code: Select all

int DoCheckShiftAndKey(int Key,WPARAM wParam, LPARAM lParam, CMotionButton &Button, CMotionButton &Button2, CMotionButton &ButtonStep)
{
	if (wParam == VK_SHIFT)  
	{
		if (lParam & 0x80000000)
		{
			// shift went up  
			if (Button2.DrawPushed)
			{
				Button.HandleButtonDown();
				Button2.HandleButtonUp();
			}
		}
		else
		{
			// shift went down 
			if (Button.DrawPushed)
			{
				Button2.HandleButtonDown();
				Button.HandleButtonUp();
			}
		}
	}

	if (Key == wParam)
	{
		if (GetKeyState(VK_CONTROL)&0x80000000) 
		{
		
		if (lParam & 0x80000000)
			{
				if (Button.DrawPushed)
				{
					Button.HandleButtonUp();
				}
			}
			else
			{

			}
		}
		else    
		{
			
			if ((lParam & 0x80000000)==0)

				ButtonStep.HandleButtonDown();
