How to make the toolbar button flashing

2011-03-01 Thread Miroslav Rajcic

I am trying to make the Pause button flash (or show any similar behaviour 
similar to that) when the pause state is active.

So far I tried many things, but none of these seem to work:
- changing the button background color
- changing the button stock icon
- changing the button relief style

Relevant code is following:

//start timer to alternate the button state
nBlinkButtonTimerID  = g_timeout_add (900, flash_pause_button_timer, NULL);

gboolean flash_pause_button_timer(gpointer data)
{
static bool bFlipFlop = false;
bFlipFlop = !bFlipFlop;

//get pointers to the relevant buttons
GtkToolbar *toolbar2 = (GtkToolbar *)lookup_widget(window1, toolbar2);
GtkWidget *tool_pause = (GtkWidget *)gtk_toolbar_get_nth_item(toolbar2, 2);
GList *children1 = gtk_container_get_children(GTK_CONTAINER(tool_pause));
GtkButton *button = (GtkButton *)g_list_nth_data (children1, 0);
g_list_free(children1);
GtkWidget *tool_stop = (GtkWidget *)gtk_toolbar_get_nth_item(toolbar2, 1);

//create two alternating colors (standard bkg and black bkg)
GtkStyle* style = gtk_rc_get_style(tool_stop);
GdkColor rgbStart = style-bg[GTK_STATE_NORMAL];
GdkColor rgbEnd = { 0, 0, 0, 0 };

//modify color
gtk_widget_modify_bg (GTK_WIDGET(button), GTK_STATE_NORMAL, (bFlipFlop)? 
rgbEnd : rgbStart);
gtk_widget_modify_bg (GTK_WIDGET(button), GTK_STATE_ACTIVE, (bFlipFlop)? 
rgbEnd : rgbStart);
gtk_widget_modify_base (GTK_WIDGET(button), GTK_STATE_NORMAL, (bFlipFlop)? 
rgbEnd : rgbStart);
gtk_widget_modify_base (GTK_WIDGET(button), GTK_STATE_ACTIVE, (bFlipFlop)? 
rgbEnd : rgbStart);

gtk_widget_queue_draw (GTK_WIDGET(button));
#if GTK_CHECK_VERSION(2,18,0)
gdk_window_process_updates (gtk_widget_get_window(GTK_WIDGET(button)), 
TRUE);

#else
gdk_window_process_updates (GTK_WIDGET(button)-window, TRUE);
#endif

/*
GtkWidget *w1 = 
gtk_tool_button_get_icon_widget(GTK_TOOL_BUTTON(tool_pause));
gtk_widget_modify_bg (w1, GTK_STATE_NORMAL, (bFlipFlop)? rgbEnd : 
rgbStart);
gtk_widget_modify_bg (w1, GTK_STATE_ACTIVE, (bFlipFlop)? rgbEnd : 
rgbStart);
gtk_widget_modify_base (w1, GTK_STATE_NORMAL, (bFlipFlop)? rgbEnd : 
rgbStart);
gtk_widget_modify_base (w1, GTK_STATE_ACTIVE, (bFlipFlop)? rgbEnd : 
rgbStart);

*/

//modify relief style
gtk_button_set_relief(button, (bFlipFlop)? 
GTK_RELIEF_NORMAL:GTK_RELIEF_NONE);


//modify stock icon
gtk_tool_button_set_stock_id(GTK_TOOL_BUTTON(tool_pause), (bFlipFlop)? 
GTK_STOCK_MEDIA_PAUSE : GTK_STOCK_MEDIA_RECORD);


gtk_tool_item_toolbar_reconfigured (GTK_TOOL_ITEM(tool_pause));

return TRUE;
}

Why doesn't any of these work ? Any tips ?

Alternating between two different stock items is quite easy when you
know how, but I had to ask here for help.
If you have two images,

--8---
img1 = gtk_image_new_from_stock( GTK_STOCK_MEDIA_PLAY,
GTK_ICON_SIZE_SMALL_TOOLBAR);
img2 = gtk_image_new_from_stock( GTK_STOCK_MEDIA_STOP,
GTK_ICON_SIZE_SMALL_TOOLBAR);

 /* convert img1 and img2 from floating references which
are deleted when no longer in use, to a normal reference.
this prevents either of the images being deleted when we
swap the play/stop button images. unref'd after gtk_main.
*/
g_object_ref_sink(img1);
g_object_ref_sink(img2);
--8---

then in your idle callback simply use gtk_button_set_image,
alternating between the two images every time the function is called
(ie you could use a static gboolean to track which button to show each
time).

then once gtk_main returns:
--8---
gtk_main();

/* free the play  stop images */
g_object_unref(img1);
g_object_unref(img2);
--8---

Re: How to make the toolbar button flashing

2011-03-01 Thread Miroslav Rajcic


Hi James,
your example uses ordinary GtkButton, not the GtkToolItem and I couldn't 
make it work in my example (although I did try to fetch underlying 
GtkButton). I've now figured how to change the icon, the key is to use 
gtk_tool_button_set_icon_widget method:


img1 = gtk_image_new_from_stock( GTK_STOCK_MEDIA_PLAY, 
GTK_ICON_SIZE_SMALL_TOOLBAR);

gtk_widget_show(img1);
gtk_tool_button_set_icon_widget(GTK_TOOL_BUTTON(tool_pause), img1);

Thank you for your help.

Regards,
 Miroslav
