Set number of visible items for GtkComboBox
Hi, ALL, In Windows it is achievable thru https://msdn.microsoft.com/en-us/library/windows/desktop/bb775915(v=vs.85).aspx. In OSX/Cocoa - thru https://developer.apple.com/documentation/appkit/nscombobox/1436741-numberofvisibleitems. Is there a way to do that for GTK+ 2 and 3?

GtkComboBox: different length of lists
Hi there, I use GtkComboBox with different length of lists. Seems to me that GTK takes the longest list as base and fills up shorter lists with zero's (see attached image). How can I avoid these zero's on display? Here's the part for the liststore in the ui-file: 2 2 2 2 2 5 5 5 5 5 10 10 10 10 20 20 20 20 50 50 50 50 100 100 100 200 200 200 500 500 500 1000 1000 2000 2000 5000 5000 1 2 5 _ Axel ___ gtk-list mailing list gtk-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-list

I think I read about it in one of the books. The book called "Visual C++ MFC Programming by Example". I'm talking about dynamically filling the combo box. I can catch the "notification:popdown/popup" signal, but if I want to write a unit test for this I should be able to imitate this behaviour programmatically. Now in case the user of my program is disabled there is a special library I can link with and use that will allow to work with such features of GTK+. Am I right?

I don't know if this was the intent, but I've always interpreted that note as meaning you shouldn't normally ever need to programmatically show the drop-down because when the user wants to see it she will click on the arrow and GTK will take care of it.

Re: GtkComboBox insanely slow on large models (GTK 2.22)
hi lothar, i'm not familiar with the details of your app, but i wonder if looking at this from the user's perspective might lead you to a way out. first, does your model assume a single list of items? or are there several levels of hierarchy involved? because when it's a single list: if, as a user, i am confronted with a combo box with 10K+ items, how am i expected to use it in a way that translates to user-friendliness? like i said, don't know your app, but a combo box with thousands of items a user is expected to select a single entry from seems, well, a little crazy. i would definitely look to breaking this up into as many levels of hierarchy as possible to make the user not go insane. (on the other hand, this doesn't necessarily solve your problem...) when, on the other hand, your model translates to combo-box lists that define several levels of hierarchy (resulting ultimately in a selection list presented to the user that is a reasonable length), then you might want to think about how to tackle the problem as part of the design. for example: - is the list data static (defined once during the lifetime of the program) or dynamic? - when static, create all the combo boxes you need at program startup and then simply attach them accordingly during the course of program execution, when and where you need them. - when dynamic, what triggers a change? - if triggered externally (i.e., not a result of user interaction), consider handling the change in the background, constructing the new models and then attaching to a new combo box widget that is used as a replacement the next time the combo box is requested. - if triggered by the user, there's not a lot (i think) you can do about GTK+ internals and how this particular processing has been designed and implemented. my app constructs combo-box lists, some quite large, so when the user dis-connects and re-connects from/to different databases, many, many data models and combo-boxes must be destroyed and recreated. for me, this translates to less than a minute of time in my worst-case scenario. and so i've decided to live with this since DB switching does not iccur very frequently. that doesn't mean a different, better solution doesn't exist, i just don't know of it. richard On Wed, Apr 27, 2011 at 10:54 AM, Lothar Scholz wrote: > Hello, > > i tried to test GtkComboBox with just 1 items (not that much) and > the app becomes totally unusable.

Hello List,
How do you do pango markup for text in a GtkComboBox?
- You create your combo box

- Give the list store to the combo
- Add a GtkCellRendererText to the combo
- Assign the "markup" attribute of the cell renderer to the column
in the store that holds the markup.
Tada !
Thanks. I'll give it a try.
Seems like massive overkill though. Couldnt this be done using a combobox
made from gtk_combo_box_new_text()?
I only need to store two items.
No it cannot, the _text() apis are the convenience that takes
care of the simple tasks such as:
a.) creating a liststore to store the text
b.) creating a cellrenderertext to display the text in the liststore
It's just a small wrapping api that does the work for the simple
case of a combo box that only shows simple text entries.
Well I managed to do it like this...
combo = gtk_combo_box_new_text();
cell_list = gtk_cell_layout_get_cells(GTK_CELL_LAYOUT(combo));
if(cell_list && cell_list->data){
gtk_cell_layout_set_attributes(GTK_CELL_LAYOUT(combo),cell_list->data,"markup",0,NULL);
}
I'm guessing this could break without notice but at the moment its a
million times better than bringing in the clunky GtkTreeModel API for
just two items.
Thanks.

No, but the other way around. You initialize the combo with the large cells, and then hack around to set smaller cells once the widget is constructed. In GIMP, we do the hack in style_set() because we need a style property that scales down font size, but I'm sure you can do it in another place too: layout = GTK_CELL_LAYOUT (gtk_bin_get_child (GTK_BIN (combo))); gtk_cell_layout_clear (layout); Then set something "small".

Unfortunately not, I've been wanting that also for Glade (particularly the cell-renderer editor does some hack that disables the ellipsizing at popup show time, but the effect is not pretty). I discussed this with Matthias briefly on irc as an "it would be nice" feature, I think essentially it needs some semantics to determine what are the limits of the popup menu to ensure the popup doesnt show up in a weird position (for instance does it align with the left side of the combo or the right side ? is there a size limit to the popup menu width at all ? possibly it should flow outside of the combo's allocation but be restrained to fit inside a parent frame or scrolled window).

Re: gtkcombobox with self internal code to the options
You shall not beg, but you should test ;-)
Yes, you can set the active option with the 'gtk_combo_box_set_active' or
'gtk_combo_box_set_active_iter'.

Re: gtkcombobox with self internal code to the options
Hello.
If I understand you correctly, you want to store name and ID of your
field inside combo box and retrieve it when needed. If this is true,
have a look at this snippet of code that demonstrates how to do this:
---
#include
enum
{
COL_NAME,
COL_ID,
NO_COLS
};
static void
cb_changed (GtkComboBox *combo)
{
GtkTreeIter iter;
GtkTreeModel *model;
gint id;
gchar*name;
gtk_combo_box_get_active_iter (combo, &iter);
model = gtk_combo_box_get_model (combo);
gtk_tree_model_get (model, &iter, COL_NAME, &name, COL_ID, &id, -1);
g_print ("Active selection: %s (id: %d)\n", name, id);
g_free (name);
}
int
main (intargc,
char **argv)
{
GtkWidget *window,
*combo;
GtkCellRenderer *cell;
GtkListStore*store;
gint i;
gtk_init (&argc, &argv);
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
g_signal_connect (window, "destroy", gtk_main_quit, NULL);
store = gtk_list_store_new (NO_COLS, G_TYPE_STRING, G_TYPE_INT);
for (i = 0; i < 10; i++)
{
GtkTreeIter iter;
gchar name[] = "Item ";
name[5] = '0' + i;
gtk_list_store_append (store, &iter);
gtk_list_store_set (store, &iter, COL_NAME, name,
COL_ID, g_random_int (),
-1);
}
combo = gtk_combo_box_new_with_model (GTK_TREE_MODEL (store));
g_signal_connect (combo, "changed", G_CALLBACK (cb_changed), NULL);
gtk_container_add (GTK_CONTAINER (window), combo);
cell = gtk_cell_renderer_text_new ();
gtk_cell_layout_pack_start (GTK_CELL_LAYOUT (combo), cell, TRUE);
gtk_cell_layout_add_attribute (GTK_CELL_LAYOUT (combo), cell,
"text", COL_NAME);
gtk_widget_show_all (window);
gtk_main();
return 0;
}

gtkcombobox with self internal code to the options
Hi all, Is possible use self codes to substitute the serial code that identify the options of a GtkComboBox? My problem in a simple explanation: I have a sqlite table with two columns, the id and the name, but the id isn't serial. To easily the load and save process of my screen will be so good if the table code (id column) substitute the serial code used that identify the options of the combo box. Have a way to do this? Thanks! ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list
GTKComboBox (space between text and button)
Hi,
I use default theme in UBUNTU 9.04 (HUMAN). But I want my GTKComboBox to
be the same appereance as GTKComboboxEntry. So I edited gtkrc and add
the following
style "combobox_style"
{
GtkComboBox::appears-as-list = 1
}
class "GtkComboBox" style "combobox_style"
Now it is better but still there is two differences:
1. Space between text and button in GtkComboBox.
2. GtkComboBox arrow button is not rounded at the top-right and
bottom-right like in GtkComboBoxEntry.
What is the solution?

Manipulating a GtkComboBox like a GtkTreeView.
I've got a GtkListStore as the model for a GtkComboBox. I'd like to be able to call gtk_tree_view_set_show_lines() and gtk_tree_view_expand_all(), but obviously a GtkComboBox is not a GtkTreeView... Is it possible to do this with a GtkComboBox? If not... is there at least a way to expand certain rows? ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list

That's very helpful. Thank you.
So basically what I'm looking for is this code:
g_signal_connect( combo->popup-shown, "notify::popup-shown",
G_CALLBACK(...),combo);
right?

Ok. Problem is, this is what the doc says:
"
Gets properties of an object.
In general, a copy is made of the property contents and the caller is
responsible
for freeing the memory in the appropriate manner for the type, for instance by
calling
g_free() or g_object_unref().
"
What scares me is the words "In general". So if this property is boolean, then
according
to the example that follows, I don't have to free the memory. But then will I
have a memory
leak?

You can read the popup-shown value by using g_object_get(). I don't
know how to read the value out of the GParamSpec passed in the callback.

Well, if you pick up an event/signal from the same page it has the function
definition for it. For example:
voiduser_function (GtkComboBox *widget,
GtkScrollType
scroll_type,
gpointer
user_data): Run Last / Action
I was kind of hoping to get something like this for this signal.

Also, do you know how do I make the function that connects to
this signal? I was hoping to write something like this:
void my_func( GtkComboBox *widget, GtkScrollType scroll_type, gpointer
user_data)
{
if( widget->popup-shown )
{
// code for list shown
}
else
{
// code for list not shown
}
}
But I don't know if this is a right prototype or not.
And the code itself, I'm not sure if it's right as well, as I can't check...

Default value: FALSE Since 2.10 " However I can't find the documentation about "notify::popup-shown" signal/event.

clicked/toggled signal for GtkComboBox
Is it possible to get a notification when the user clicked on a GtkComboBox? That is, before the user actually makes a selection (and thus the "changed" signal is emitted). It seems to be possible to connect to the "focus-in-event", but that doesn't work when the combo box doesn't focus (gtk_combo_box_set_focus_on_click() set to FALSE). Browsing through gtk's code, it seems that what I am requesting is for the combo_box->priv->button's "clicked" or "toggled" signal to be exposed, which doesn't seem to be done currently.

GtkComboBox problem
Hi again, I've just noticed another problem after upgrading to GTK 2.14.4. This one is with GtkComboBox and happens on both Windows and Linux. It doesn't happen with GTK 2.12.12. I have a combo box to which I add about 150 entries, and I see that the look of the combo box has changed between these releases. With GTK 2.12.12 when the list opened it would extend from its location in the app up to the top of the screen, and would have a traditional scroll bar on its right side. With GTK 2.12.14 it extends all the way from to top bottom of the screen and has separate scroll-up and scroll-down arrows at top and bottom. The problem is that when it first opens, entries are only populated in the bottom half of the visible list area, from the position of the control in the app down. The top half from there to the top of the screen is empty - a big blank area. If I scroll down the entries scroll up into that area, and once I've scroll far enough for them to reach the top, then it is OK and the blank area is gone (if I scroll back up it does not reappear). I've uploaded a screenshot of it doing this here: http://slracing.org/files/ComboBoxBug.jpg Anyone know if this is this a known problem?

gtkComboBox problem
I'm utilizing a combo_box in my application and am experiencing... difficulties with it... 1. When opened, the box extends to the top and bottom of my screen (I assume due to the amount of items contained within it) 2. Since the selected item is positioned at the same place on the y-axis as the box itself, when opened there is just gray, blank space in the box where no items exist. Any ideas on what I can do to solve this? there is no model connected to this box, by the way. Any help is appreciated. Thanks!

GtkComboBox Question
Hi, I create a new GtkComboBox with gtk_combo_box_with_new_model. In the model I put a pixbuf in a GtkListStore. In the GtkComboBox there is a GtkToggledButton, my question is: Can I remove the toggle button or modify its size? Maybe in the gtk resource file? I want a combobox without the button which will take an area and the width of the combobox will be the same with my pixbuf. Any suggestions or help will be appreciated.

Re: Set Allignment of GtkComboBox Columns
Hi, I compiled the gtkcombogrid, but my problem is still existing as there is no way avaibale to remove this situation. Infact in gtkcombogrid there is fixed column size which makes a separate list view. I made the combox itself list view where i placed the different columns. Due to dynamically changes comes in combobox columns modify its size and looks not alligned. So i want to modify the size of all columns run time due to effects of larger columns.

Then it'd be better to add an item "Broadcast to all users". How many users of your application would assume that selecting "nothing" means "broadcast to all users" anyway? Automatically selecting the first item of the model once the model is set sounds like a sane option (esp. since that's what nearly every application does right now, as an "empty combobox" is more or less confusing to the casual user). > BYtE, > Diego.

GtkComboBox
Hi, I asked this question previously but there were no replies. So here I am again. I would like to disable a particular entry in the GtkComboBox. I am using a GtkComboBox with a model and supplying it cell renderers. If disabling a particular entry is not possible, can I at least change the look of that entry like background or foreground so that the user knows that it is disabled. How can I do that? I see some functions like gtk_cell_renderer_render, what does this do? Thanks ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list
GtkComboBox again
Hi, Is there any way to add a separator in the GtkComboBox. I am using combo box with a tree model. Also I need to add markup properties that applies to a whole column. How do I do that? I tried the following code, but it doesn't work. ts = gtk_tree_store_new(1,G_TYPE_STRING); GtkWidget *tv = gtk_tree_view_new_with_model(GTK_TREE_MODEL(ts)); GtkCellRenderer* cr = gtk_cell_renderer_text_new(); //g_object_set(G_OBJECT(cr),"weight",1000,NULL); //this works g_object_set(G_OBJECT(cr),"markup","some text",NULL); GtkTreeIter iter; gtk_tree_store_insert(ts, &iter, NULL, 0); gtk_tree_store_set(ts, &iter, 0, "FIRST",-1); GtkWidget* combo = gtk_combo_box_entry_new_with_model(GTK_TREE_MODEL(ts),0); gtk_cell_layout ... One more problem that I had was with disabling of a particular entry in the combo box which doesn't seem so easy. All these things were accomplished quite easily with GtkOptionMenu which is now deprecated in preference to GtkComboBox. But GtkComboBox doesn't seem to have any easy ways to achieve the same. Why were things designed like this? or am I missing something here? Can anyone point to some detailed documentation on the net related to GtkComboBox or migrating from GtkOptionMenu to GtkComboBox?

Re: GtkComboBox
Hi Michael, If I am not wrong, with tree model we can even display images and text together as part of the menu items. This is the reason why I chose to use tree model. If there was only text then you are correct. Thanks to Neumann for pointing out what I was missing in the code. -Pramod On 5/31/05, Michael Ott <[EMAIL PROTECTED]> wrote: > Hello Pramod! > > > I was trying out GtkComboBox. I have Gtk-2.4.

Why so difficult. You can use gtk_combo_box_append_text and need no tree model CU Michael -- Michael Ott, e-mail: [EMAIL PROTECTED], www.zolnott.de I am registered as user #275453 with the Linux Counter, http://counter.li.org. pgpY5fPs6dhwV.pgp Description: PGP signature ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list

Your combobox only has a model. You need to add a cell-renderer to the combo-box. Sven ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list
GtkComboBox
Hi, I was trying out GtkComboBox. I have Gtk-2.4. I have created a GtkTreeModel and populated the corresponding GtkTreeStore. But when I run the program, the entries are not shown. Why is this happening? I am attaching the program here: GtkTreeStore *ts = gtk_tree_store_new(1,G_TYPE_STRING); GtkWidget *tv = gtk_tree_view_new_with_model(GTK_TREE_MODEL(ts)); GtkCellRenderer* cr = gtk_cell_renderer_text_new(); GtkTreeViewColumn* tvc = gtk_tree_view_column_new_with_attributes(NULL, cr, "text", 0, NULL); gtk_tree_view_append_column (GTK_TREE_VIEW(tv), tvc); gtk_tree_view_set_headers_visible(GTK_TREE_VIEW(tv), FALSE); GtkTreeSelection* TS = gtk_tree_view_get_selection(GTK_TREE_VIEW(tv)); gtk_tree_selection_set_mode(TS, GTK_SELECTION_BROWSE); GtkTreeIter iter; gtk_tree_store_insert(ts, &iter, NULL, 0); gtk_tree_store_set(ts, &iter, 0, "FIRST",-1); gtk_tree_store_insert(ts, &iter, NULL, 0); gtk_tree_store_set(ts, &iter, 0,"SECOND",-1); GtkWidget* combo = gtk_combo_box_new_with_model(GTK_TREE_MODEL(ts)); gtk_container_add(GTK_CONTAINER(dialog),combo); gtk_widget_show(combo); Can anyone please point out, why the entries are now show n in the combo box?

Re: Setting tooltips on GtkComboBox
Is there a list of GTK_NO_WINDOW widgets? Or is there an easy way to tell from the GTK manual that a widget is GTK_NO_WINDOW? I'm sure this is the cause of my combobox event problems and I never thought that the combobox wouldn't have its own window. The other controls I've run into without windows have all made a lot of sense, frames, labels, etc. Labels because they need to be as lightweight as possible, Frames so they are "transparent", etc. However, it seems like the combo box, being one of the most complex controls in GTK, wouldn't incur much overhead if it had a window by default.
