Re: builder.ui and GtkDrawingArea size

GtkDrawingArea is a widget, so you just write the property width and height
in the builder.ui, done! 😀

Solved.

Someone have a example of how to create a custom widget with cairo in C?

Hi,

I create a drawing area to draw a circular gauge with cairo.

GtkWidget *drawing_area = gtk_drawing_area_new ();
gtk_widget_set_size_request (drawing_area, 100, 100);
gtk_box_pack_start (GTK_BOX(gtk_builder_get_object(builder,
"box30")),drawing_area,FALSE,TRUE,0);

The problem is that the drawing area is not 100x100 but the entire of
screen.

This is the callback function:



gboolean on_circular_gauge_draw(GtkWidget *widget, cairo_t *cr,
gpointer user_data)
{

  int width, height;
  gint percentage, linewidth;

  width = gtk_widget_get_allocated_width (widget);
  height = gtk_widget_get_allocated_height (widget);


  linewidth = (MIN (width, height) / 2.0 * 30.0) / 100.0;

  cairo_set_source_rgba (cr, 1.0, 1.0, 1.0, 0.6);
  cairo_set_line_width (cr, linewidth);
  cairo_arc(cr, width/2.0, height/2.0,  MIN (width, height) / 2.0 -
linewidth, angle1, angle2);
  cairo_stroke (cr);

  cairo_set_source_rgba (cr, 0.0, 0.9, 0.0, 1.0);
  cairo_set_line_width (cr, linewidth);
  cairo_arc(cr, width/2.0, height/2.0, MIN (width, height) / 2.0  -
linewidth, 180.0  * (M_PI/180.0),315.0  * (M_PI/180.0) );
  cairo_stroke (cr);



  return FALSE;
}

Re: GtkDrawingArea size request

2017-06-22 Thread Eric Cashon via gtk-app-devel-list 

 
Hi Ruben, 

You might consider allowing the gauge to expand with the window size. This 
makes the gauge a lot more flexible. When drawing a gauge it is useful to get a 
general coordinate drawing on screen that you can check your gauge drawing 
with. Both cartesian coordinates and radial coordinates are useful to check 
your drawing. There is a general layout drawing in the following.

https://github.com/cecashon/OrderedSetVelociRaptor/blob/master/Misc/cairo_drawings/gears2.c

You can use set sizes if you want to also. To keep your drawing area window 
size a set size check your vexpand and hexpand properties. Make sure they are 
false. Try using a GtkGrid instead of a GtkBox. Put the drawing area in a 
scrolled window and put that in the grid.

I have done some work drawing gauges and have a couple packaged as widgets. 
There are also some drawings of clocks, gauges, gems and gears in the above 
github cairo_drawings folder. Some resize as circles and some as ellipses. They 
might be helpful getting something that you can test a gauge drawing with.

Eric

Re: Fwd: GtkDrawingArea size request

2017-06-21 Thread Chris Moller 
There's no reason the drawing area code you're showing shouldn't work.  
The most obvious possibility is that the size of your enclosing widget 
(GTK_BOX(gtk_builder_get_object(builder, "box30"))) isn't set right--the 
default is that your drawing area will expand to fill its parent.

Hey

if you use Gtk+-3.0 you can use

GtkWindow* window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_window_set_resizable(window, FALSE);

This should prevent the resizing and disables the grip.

I would add a wrapper GtkAlignment around my drawing area, set it's
xalign and yalign propertes to 0.5, it's xscale and yscale to 0, pack
GtkDrawingArea inside it and fix it's size using
gtk_window_set_size_request().

Have a look at this simple app:

#include 

#define WIDTH  300
#define HEIGHT 400

static gboolean
cb_draw (GtkWidget  *w,
 GdkEventExpose *e)
{
  cairo_t *cr = gdk_cairo_create (e->window);
  cairo_set_source_rgb (cr, 1.0, 1.0, 0.0);
  cairo_paint (cr);
  cairo_destroy (cr);

  return TRUE;
}

int
main (intargc,

  GtkWidget *window,
*align,
*area;

  gtk_init (&argc, &argv);

  window = gtk_window_new (GTK_WINDOW_TOPLEVEL);

  align = gtk_alignment_new (0.5, 0.5, 0, 0);

I guess you can have a drawingarea of fixed size if you put it in a
container of fixed size, ie. make the window fixed size, see

http://developer.gnome.org/gtk3/stable/GtkWindow.html#GtkWindow--resizable

With cairo it is easy to scale your graphics, and you get all these nice
stuff like anti-aliasing, transparency and much more. But cairo is not
very fast -- for my current toy project
(http://www.ssalewski.de/PetEd.html.de) I had to carefully figure out
which redraw operation is really necessary for updating the display. A
complete redraw can take more than 100ms -- but now I have fixed that by
using bounding boxes for each elements, and redrawing only what has
changed. But for fast action games OpenGL may be a better choice. When
your application does not need fast graphics, then you may also consider
other languages than C -- I am using Ruby currently, next time I may
give Vala a try...

I think the halign and valign properties are what I was looking for. It
seems that, if I do an align center, that the widget never grows larger
than its requested size, though it still can shrink.

code:
--
gtk_widget_set_size_request (my_widget, 256, 256);

gtk_widget_set_halign(my_widget, GTK_ALIGN_CENTER);
gtk_widget_set_valign(my_widget, GTK_ALIGN_CENTER);

Bump.

I'm trying to look through some other projects to see how this is done,
but I would appreciate it if anyone happens to know of the top of their
head.

GtkDrawingArea size

2012-03-06 Thread Christopher Howard 
Hello again. So, I recently started a project to create a certain board
game (in C) using gtk+, and I just started learning gtk+. I was planning
to draw the board graphics, pieces, etc. all into one GtkDrawingArea.
So, how do I fix the size of the drawing area so it doesn't get larger
or smaller than my graphics?

The alternative, I suppose, would be to scale everything against the
actual size of the drawing area (cairo can resize bitmap images, no?)
but presumably that would be a lot more complicated to code, and I would
still need to constrain the proportions of width to height.
