gtk-apply icon 1 Month, 4 Weeks ago

Karma: 0

First up thanks for a awesome resource. I've already gotten a lot of what I need done just by reading your examples.

Basically what i'm chasing is a way to add an icon to a hbox.

The example is a log output slowly being appended to a vbox.

Each log line will be text with either a green tick for success or a red cross for failure. I see both of these icons are there by default.

Thanks for any help or direction you can give.

Tom

So far I'm trying to use something like the following. Although it doesn't seem to work.

Code:

$hbox = new GtkHBox();
$img = new GtkImage();
$img->render_icon('gtk-apply', Gtk::ICON_SIZE_DIALOG); 
$hbox->pack_start(new GtkLabel('Testing'), 0, 0);
$hbox->pack_start($img);
$vbox->pack_start($hbox,0);
$window->show_all();

OK sorted it ;)

changed

Code:

$hbox = new GtkHBox();
$img = new GtkImage();
$img->render_icon('gtk-apply', Gtk::ICON_SIZE_DIALOG); 
$hbox->pack_start(new GtkLabel('Testing'), 0, 0);
$hbox->pack_start($img);
$vbox->pack_start($hbox,0);
$window->show_all();

Code:

$hbox = new GtkHBox();
$img = GtkImage::new_from_stock('gtk-apply', Gtk::ICON_SIZE_DIALOG);
$hbox->pack_start(new GtkLabel('Testing'), 0, 0);
$hbox->pack_start($img);
$vbox1->pack_start($hbox,0);
$window->show_all();

Now doing what I wanted. T

Hi,

Glad you got it working.

Since yours is a log output, assuming the log will grow more than a screen size, here are a few "enhancements" you might want to try:

- you can use a treeview stuffed inside a scrolledwindow
- you can even stuff the vbox inside a scrolledwindow so that user can scroll the vbox
- you can also use a textview

There are ready sample codes for any of the above. If you have problem finding them, let me know, ok?

Regards,

Thanx for your reponse.

Already got sorted a lot of it now.

Have placed the scrolledwindow in a vbox.

Then another vbox in the scrolled window via add_with_viewport.

Have gotten a process spawned via idle_add such that processing automatically starts. Also got the window scrolling and the scroll bar going in the right direction.

Only two outstaning things at the moment are,

a) I'd like to change the background color of the scrolling vbox to be white.

b) I'd like for the application to close itself if it doesn't encounter any errors. At the moment if I call window->destroy or GTK::quit() I get a errors and the php process doesn't end.

Attached is an example of my app thus far.

a) I'd like to change the background color of the scrolling vbox

Please refer to
Sample Code 8: How to set the background color of GtkLabel?

Like the GtkLabel, GtkVBox is also one of those "transparent" widgets. So you need to stuff the vbox inside a GtkEventBox and set the bg color on the eventbox.

b) I'd like for the application to close itself if it doesn't encounter any errors. At the moment if I call window->destroy or GTK::quit() I get a errors and the php process doesn't end.

What's the error message that you get?

Normally you can quit an application using GTK::quit(). I suspect you encounter some error because you didn't properly stop the Gtk::idle_add() or Gtk::timeout_add() before GTK::quit(). Try do a Gtk::idle_remove() before you do GTK::quit(). (Note: you need to take note of the handle id, which is returned by Gtk::idle_add(). You need the handle id for Gtk::idle_remove().)

OK the background color certainly was a simple job.

Examing my code compared to your examples of idle_add .. you use a class for your long task where I'm only calling a function.

I'm starting to wonder if this is somehow the cause ?

Code:

$window->add($vbox);

$window->show_all();

Gtk::idle_add(start_processing()); 

Gtk::main();

The start_processing function runs a for loop at the moment and adds those green ticks and what not to the scrolledwindow. At the end of which I'd like to exit. Once again any thoughts would be appreciated. T

Sorted ;]

Changed

Code:

$window->add($vbox);

$window->show_all();

Gtk::idle_add(start_processing());

Gtk::main();

Code:

$window->add($vbox); 

$window->show_all(); 

$idleID = Gtk::idle_add('start_processing'); 
	
Gtk::main();

The idle_add lines being where I had screwed up. This resolved my exiting issues, warnings in the logs and awkward messages on the console. Thanx again for your help. T
