Why is there so little training and examples on TouchGfx !!!!

Hi Guys

How on earth does ST expect anyone to use, learn and embrace their products when there seem to be so little help , videos training??

TouchGFX is appalling for step by step examples, YES it's free, but no value to engineers if you have no idea or can't understand Toucgfx  

I have been days traying to create an event  from a custom container with a toggle switch

under the container I have created an event for a toggle button

I have called the container panel which holds the toggle button and event

under generated gui I see the generated event handler

I then want to copy that event handler in to panel.cpp and create a new event for a custom container

 

The compiler just errors every time ????? I ready to lunch the PC 

There must be a better easier way than touch GFX, im sure its great if you know what on earth you are doing

this is the generated code

when i try to add this to add this to panel.cpp     (the custom container, just compiler errors ???

void PanelBase::buttonCallbackHandler(const touchgfx::AbstractButton& src)
{
if (&src== &ch1_tog)
{
//ev
//When ch1_tog clicked call virtual function
//Call ev
ev();
}
if (&src== &ch8_tog)
{
//JIMJIM
//When ch8_tog clicked call virtual function
//Call JIMJIM
JIMJIM();
}

I normally program in C

I understand classes and object orientated code,

just have no idea how to used touchgrfx ??? there is so little basic easy to understand examples

Then why you place PanelBase into other class and ask why compiler say error.?

I agree learn TGFX is not easy. My tip is half year.

I disagree, examples is in designer , but in new version is more complicated to open.
