Re: Viewer color

Hi Tom.
With a mouse, everything is clear, thank you. I thought the view rotation button should work but it doesn't.
Touch input needs such a button.

Re: Viewer color

Sorry, I figured out how this button works.
Everything works for mouse input. But you need to add an input mode button for the touch monitor
How can I add this button ?

Regards,
Taras.

Re: Viewer color

I suppose you could alter the behavior so that whenever the xy Rotation button is down then the Left mouse does normal rotation (instead of translation) and the right mouse does xy rotation (instead of zoom). See the function

void COpenglCtl::OnMouseMove(UINT nFlags, CPoint point)

and related flags:

m_LeftButtonDown
m_RightButtonDown
m_xyRotation (Tool bar button state)

HTH

Re: Viewer color

Thank you Tom!
I redid it the way I need it.
// Both : rotation
if(m_LeftButtonDown && m_xyRotation) //&& m_RightButtonDown)m_LeftButtonDown
{
//if(!m_xyRotation)
//{
m_yRotation -= (float)(m_LeftDownPos.x - point.x) * m_SpeedRotation * TimeFactor;
m_xRotation -= (float)(m_LeftDownPos.y - point.y) * m_SpeedRotation * TimeFactor;
//}
//else
//{
//m_zRotation -= (float)(m_LeftDownPos.x - point.x) * m_SpeedRotation * TimeFactor;
//}
m_LeftDownPos = point;
m_RightDownPos = point;
InvalidateRect(NULL,FALSE);
}
Now if the button is not pressed, then we move; if it is pressed, we rotate.
This will be more convenient for touch input.
I have one more question. The jog buttons work fine for me only when I double-click. Where can I look in the code to fix this ?

Regards,
Taras.

Re: Viewer color

Hi Taras,

I'm not sure. Did you mean double touch?

The Jog buttons are handled in the CMotionButton class. The Windows message ON_WM_LBUTTONDOWN calls

Code: Select all

``````void CMotionButton::OnLButtonDown(UINT nFlags, CPoint point)
{
ForceDisableFocus=false;
if (HandleButtonDown()) return;
CButton::OnLButtonDown(nFlags, point);
}
``````

to do the motion. Apparently on your touch screen a single touch doesn't generate this message. Maybe it is treated as a click (or Activate) rather than a left mouse down.

You might try adding one of the Microsoft Windows messages described here. Maybe: ON_WM_MOUSEACTIVATE() ?

Re: Viewer color

Thank you Tom!
Tried to listen ON_WM_MOUSEHOVER().
It worked, but I wasn't happy with the result.

MotionButton.h
afx_msg void OnMouseHover(UINT nFlags, CPoint point);

MotionButton.cpp
BEGIN_MESSAGE_MAP(CMotionButton, CImageButton)
ON_WM_TIMER()
ON_WM_MOUSEMOVE()
ON_MESSAGE(WM_MOUSELEAVE, OnMouseLeave)
//ON_MESSAGE(WM_MOUSEHOVER, OnMouseHover)
ON_WM_MOUSEHOVER()
ON_WM_KILLFOCUS()
ON_WM_CAPTURECHANGED()
ON_WM_LBUTTONUP()
ON_WM_LBUTTONDOWN()
END_MESSAGE_MAP()

void CMotionButton::OnMouseHover(UINT nFlags, CPoint point)
{
ForceDisableFocus = false;
if (HandleButtonDown()) return;
CButton::OnMouseHover(nFlags, point);
}
Maybe there are messages from touches for their processing?
The touch input response is weird.
At the first touch, the movement value changes slightly and immediately stops, and only after a double touch does the axis begin to move without stopping.
Where can I see touch input messages like this? - https://docs.microsoft.com/en-us/cpp/mf ... w=msvc-170
I can post a video of the behavior of the pane.

I don't know you might Google for it.

There is a Visual Studio Tool Under Tools Called Spy++ that "spies" on Window messages. You can Select Spy | Log messages

Then drag the finder tool to one of the motion buttons. All Windows messages related to that button should then be logged. Then "touch" the button and see what messages are sent and consider if any might be useful.

Re: Viewer color

Hi Tom.
(Spy++) I think it will help me figure out the problem.
I figured out how to work with it on my work computer. Is it possible to install it on my touchpad without the visual studio package?
If not, then you will have to install the studio to check messages from touch input.
Thank you Tom! You are my guide to the world of C++.

Taras.

Re: Viewer color

I also have a suggestion to rename the post to a touch screen KMotionCNC .

I don't think there is an easy way to change the name of a Thread. You might start a new Thread and include a link to this Thread.
