[License]

Hello,

I am close to finish the design of a product for a customer. Is that a problem if i buy Ugxf license myself ? Is that legally ok for my customer ?

[Hardware acceleration]

Hello,

Ugfx is announced to support hardware acceleration but what are supported targets for that ?

Is Linux Framebuffer supported ?

Thank you.

It works. Thank you for your help.

Hello,

I wish to create a Screenshot. How can I access to the actual display buffer to read pixels please ?

Thank you. 

[Double buffer style]

Thank you for your help.

[Online font converter]

Thank you for your help.

[Online font converter]

Hello,

Online font converter is broken, could you repair it please ?

Thank you.

[Double buffer style]

If you take a simple button, you can see that the text draw is after the retangle draw. I modified some controls to use pixmaps for compositions and display is very clean. I can move controls with no blink effect now

Thank you all people for your help.

[Hide button]

Ok i found, there was a timer that sometimes was fighting against me. I moved to immediate configuration and i was able to do everything i wanted.

Thank you all people for your help.

[StatusBar _mouseDown not fired]

It works for one page but not the others. How to manage statusbar parent if it's called in multiple pages ?

[StatusBar _mouseDown not fired]

Could it be because page containers and status bar overlap ?

[StatusBar _mouseDown not fired]

I tried without any success. Another test ?

[GWIN_REDRAW_IMMEDIATE and buttons]

A make clean fixed it. Thank you for your help.

[GWIN_REDRAW_IMMEDIATE and buttons]

Hello,

How can i use GWIN_REDRAW_IMMEDIATE and have button pressed render please ?

[Hide button]

Ok i found about the lock, my mistake sorry.

[Hide button]

Hello,

It's more complex that i imaginated. I tried to move on GWIN_REDRAW_IMMEDIATE = GFX_ON but gwinHide(ghMyPageContainer1); is never goes out. Do i missed something ?

[Force a button to render in a pixmap]

it was another problem the source of the segmentation fault.

 

[Hide button]

i replaced 

gwinSetVisible(ghPushbutton1, FALSE);

with

ghPushbutton1->flags = ghPushbutton1->flags & ~GWIN_FLG_SYSVISIBLE;

and it works

[Hide button]

Hello, 

I want to hide a button before animate another one.

That doesn't work (strange colors at old position):

gwinSetVisible(ghPushbutton1, FALSE);
GWidgetObject * temp_control = ((GWidgetObject *) ghPushbutton1);
gdispGFillArea(temp_control->g.display, temp_control->g.x - border, temp_control->g.y - border, temp_control->g.width + 2 * border, temp_control->g.height + 2 * border, GFX_BLACK);

That works (hidden but can be clicked):

GWidgetObject * temp_control = ((GWidgetObject *) ghPushbutton1);
gdispGFillArea(temp_control->g.display, temp_control->g.x - border, temp_control->g.y - border, temp_control->g.width + 2 * border, temp_control->g.height + 2 * border, GFX_BLACK);

It looks like if set invisible launched a background task.

Do I missed something ?

 

[Force a button to render in a pixmap]

Hello,

I want to force a button to render in a pixmap. Is there any clean way ?

I tried a dirty hack with "my_button->g.display = pixmap;" but sometimes i get a segmentation fault like if it was Something else that use it. How to do that cleanly please ?

 

 

[Double buffer style]

Hello,

Thank you for your response.

 

[Double buffer style]

Hello,

I already asked a close question how to use a double buffer. Response was not possible. I have some blink issues when i move a simple buton due to buton background fill. Is there any way to prepare a full render in a pixmap and swap (unsynchronized with display) when done.

If not, is there any way to draw completly a control on a pixmap and write it on display when all processing was done ?

Thank you

ps: my target is linux framebuffer.

[StatusBar _mouseDown not fired]

Hello,

I will try that asap.

 

[StatusBar _mouseDown not fired]

Hello,

I tried to implement a statusbar based on your exemple on my project. It's a Linux with touchscreen and _mouseDown is never called (i am sure that touch works because button events are ok)

static void _mouseDown(GWidgetObject* gw, coord_t x, coord_t y)
{
	printf("_mouseDown (%d,%d)\n", x, y); // never called
	// ...

in my main

void * events_function(void *arg)
{
	printf("events_function start\n");
	while(1) 
	{
		// Get an Event
		GEvent * pe = geventEventWait(&gl, 1000);

		// ...
	}
}


int main()
{
	// ... 

	geventListenerInit(&gl);
	gwinAttachListener(&gl);

	// ...


	if (pthread_create(&events_thread, NULL, events_function, NULL) == -1) 
	{
		perror("pthread_create events_thread");
		return EXIT_FAILURE;
    }

	// ...

 

Do you have an idea of what can i check ?

[Custom draw possible issue]

Hello,

When i draw my images, it looks like x and y are expected values + 2

This is the code

void gwinMyButtonCustomDraw(GWidgetObject *gw, void *param) 
{
	const GColorSet *	pcol;
	coord_t				sy = 0;

	if (gw->g.vmt != (gwinVMT *)&buttonVMT)	return;
	

	gdispImage * temp_images = (gdispImage *)param;
	gdispImage * temp_image = NULL;
		
	if (!(gw->g.flags & GWIN_FLG_SYSENABLED)) 
	{
		temp_image = &(temp_images[BUTTON_DISABLED]);
	} 
	else if ((gw->g.flags & GBUTTON_FLG_PRESSED)) 
	{
		temp_image = &(temp_images[BUTTON_ACTIVE]);
	} 
	else 
	{
		temp_image = &(temp_images[BUTTON_IDLE]);
	}
	
	gdispGImageDraw(gw->g.display, temp_image, gw->g.x, gw->g.y, gw->g.width, gw->g.height, 0, sy);
	
	if (gw->text[0] != '\0')
	{
		pcol = getButtonColors(gw);
		gdispGDrawStringBox(gw->g.display, gw->g.x+1, gw->g.y+1, gw->g.width-2, gw->g.height-2, gw->text, gw->g.font, pcol->text, justifyCenter);
	}
}

 

And a schematic (i noticed that because my button image was a prolongation of the background)
