GTK+ itself doesn't currently offer any printing support, so the question doesn't really involve GTK+ directly. You need to either 1) Open the printer device (e.g. /dev/usb/lp0) and write data to it. 2) Open a pipe to the printer spooler (e.g. lpr -P queuename) and then write the job data and close the connection. Thanks for clearing this up. By a POS printer, I take that to mean a 40 col receipt printer sort of thing. These are basic devices which are basically ASCII thermal printers plus some additional control codes and possibly some extra bitmap raster graphics mode. For these you just send the control codes inline with the text you're printing to either (1) or (2) above. Your program is entirely responsible for the formatting, layout and cutting etc. yes, that's pretty much what I mean. What do I use to do layout and formatting before dumping to the printer? Where would I find information on the extra control codes? I'm sure not all printer manufactureres publish this sort of thing. How does that work with CUPS? For the work I do, I send jobs to a receipt printer via CUPS. After completion of a transaction, the receipt gets printed after a barely noticeable delay ( 0.5s). Your best bet is to use a spooler. This also makes networked operation totally transparent, and is far more flexible. You can use libcups, lpc or lpstat etc. to get a list of all available printers if the user needs to choose one. Ok, so I probably will use a print spooler (CUPS), what do I need to do? I'll look at the CUPS docs, but some fast direct pointers are nice. Thanks in advance. -- .''`. Carl B.

more on g_strconcat problem
Ok, I've definately nailed the problem down to an issue with the check
button in my data entry box. But it still doesn't make sense. consider
the following code:
idRequired = gtk_toggle_button_get_active(GTK_TOGGLE_BUTTON(lookup_widget(customers,
cust_id_req)));
g_print(ID Required status: %d\n, idRequired);
toggleTest = (gint)idRequired;
g_print(ID Required status: %d\n, toggleTest);
the above code prints 0 if the checkbox is unchecked and 1 if it is
checked.
With that in mind, consider the following additional code:
sql = g_strconcat(insert into customers (id_req) values(', toggleTest, '),0L);
g_print(First sql: %s\n,sql);
This code prints the following when the checkbox is unchecked:
insert into customers (id_req) values('
so it doesn't even complete the string. That same code crashes with a
segfault 11 if I check the checkbox in the dialog.
This makes absolutely NO sense what so ever!
Please help, this is driving me NUTSO!

data between windows?
I'm writing an application that uses a lot of data entry features with a MySQL (currently) back end. One of my data entry screens also includes a find button. Clicking the find button brings up another small window to type a portion of the client phone number. This in turn will bring up a dialog with a list of matching results (not yet implemented). The person doing the data entry would then select the correct client and have the data appear in the data entry window for updating purposes. My question is, what do you folks think is the best way to accomplish this? I'd like to reuse the same window for find/update as I do for entry/add as that window is often already open. But I need to get data from a dialog that appears later BACK into my data entry window. Thoughts? -- .''`. Carl B.

properties for GtkCellRenderText -- Whoohoo it works!
This message ties into an earlier message where I stated I would try out
some code to see if I could change the attributes of text in my
GtkListStore. It works quite nicely. Here's what happens:
1) user selects an item in my GtkTreeView (note: in this case just a
single column view).
2) User clicks a button and the text at that selection turns red!
Here's what I did:
1) I have an enumerated type for the storage model
enum
{
DATA_COLUMN,
MODEL_ATTRIBUTES,
N_COLUMNS
}
2) Created a callback for the the button press:
void on_button_clicked (GtkButton *button, gpointer *userData)
{
do_color_test(gtk_widget_get_toplevel(button));
}
3) now, in the do_color_test routine, I need to do several things:
- get the view
- get the model
- get the current selection
- return the proper iter for the selection
- set the attribute to red for the current selection
void do_color_test (GtkWidget *theWindow)
{
GtkWidget *theView = NULL;
GtkListStore *theListStore = NULL;
GtkTreeIter theIter;
GtkTreeModel *theModel = NULL;
GtkTreeSelection *currentSelection;
theView = lookup_widget(theWindow, atreeview);
theModel = gtk_tree_view_get_model(theView);
if (GTK_IS_LIST_STORE (theModel))
{
theListStore = GTK_LIST_STORE (theModel);
g_print(theModel is a ListStore\n);
}
/* get the current selection from theView */
currentSelection = gtk_tree_view_get_selection(theView);
/* now that we have a selection, get the exact location in theIter
*/
if (!gtk_tree_selection_get_selected(currentSelection, theListStore,
theIter))
{
g_print(no current selection!!\n);
}
/* set the color for that row to red */
gtk_list_store_set(theListStore, theIter, MODEL_ATTRIBUTES, red,
-1);
}
There are probably more efficient methods of doing this. For example, do
I need to call gtk_tree_view_get_selection at all? Some obvious debug
code can also be elminated but that's the jist of it.

CellRenderText properties question.
The Gnome 2.0 porting docs contain the following information on the GtkCellRender widget (under new widgets in the docs): * Cell renderer properties can be set per-renderer or per-cell (based on data in the model). So for example, the text renderer has a foreground property for the foreground color. You could set the foreground color globally for an entire column, or you could have the foreground property change per-cell according to data in the model. * For a given cell renderer, multiple fields in the model can affect it. For example, if your mail client model has a boolean field indicating unread message, and a string field indicating subject, you can set the bold property of the cell from the unread flag and the text property of the cell from the subject. Looking at the API docs for GtkCellRender and GtkCellRenderText, I see the following description under gtk_cell_renderer_text_new (): ...Also, with GtkTreeViewColumn, you can bind a property to a value in a GtkTreeModel. For example, you can bind the text property on the cell renderer to a string value in the model, thus rendering a different string in each row of the GtkTreeView. However, I can't really find any code examples of how to do anything suggested in these docs. For example, I have a GtkTextView that only has a single column in it. When I click a button in my window, I want to find out the current selection in that TreeView and set it's text to Red or Bold or something. I can't seem to find anything that shows how to get the exact cell and then change its attributes. I can do it globably for a column (and have for testing) but not on a single cell. These docs seem to imply that I need some further data in my cell model to apply an attribute to. So, it seems like I have to have an extra invisible column in my model that holds text attributes, update the column text with a new string (say to red from black in order for the text in the visible column to have the attribute change. This seems very confusing to me. The docs say based on data in the model but it's not clear what that means, if it's actual attributes stored in the model, or just change based on a programmatic condition (col 1 is true so set text to bold). How can I change attributes on a single cell without having extra data in my model or do I really need the extra data in my model? I'm sure I'm missing something obvious but the docs are confusing. Also, storing extra attribute data in my ListStore adds memory overhead. Additionally, I see this description for gtk_tree_view_column_cell_set_cell_data: Sets the cell renderer based on the tree_model and iter. That is, for every attribute mapping in tree_column, it will get a value from the set column on the iter, and use that value to set the attribute on the cell renderer. I'm sorry but that's not very clear, and in fact it's extremely confusing. Maybe RedHat could hire me as a technical writer (I have several years experience at this and worked for Metrowerks as a professional technical writer). Any help is greatly appreciated. -- .''`.

If only it could be possible to map values to attributes (1=red, 2=blue and so on...) or have a hex value that can then be used for the color. Then a user can use the color selector to pick a color for certain cells. However, I find that interface rather awkward to use in that instance, again because it can't be determined programatically or you have to change the column the cell looks at on the fly which is awkward. -- .''`.

The gtk-demo as found in the demos directory of the GTK+ source tree seems like a good place to look for such examples.

cell renderers question.

Some views have many columns, a couple have 2, and one has 1 column. I call gtk_tree_view_append_column for each column in each view. Before I do that, I make a call to gtk_cell_renderer_text_new().

blinking cursor/focus problems?
I set up a bunch of widgets in a window. some are GtkTreeView, some are GtkEntry widgets, one is a menu, one is a button, one is a GtkTextView. For the GtkEntry and GtkTextView's, I have the cursor/text visible and editable selected in Glade. All widgets have can focus set. Now, when I run my application, I can click around, but no blinking cursor in the GtkEntry or GtkTextView (though I can type text) and selecting rows in the GtkTreeView's select in a grey state (I can't really think of a word, maybe inactive but selected, or no focus, but selected). Now, if I right click in the GtkTextView or click my menu, suddenly the cursor can flash, and my row selections appear in the proper highlight color. Why is this? What am I forgetting to do? I tried to set one of the widgets to has focus in Glade, but that didn't change anything. Someone know what I'm doing wrong? -- .''`. Carl B.

I don't mean/want to be harsh, but how can the developers of Gtk+ expect developers to write apps when there is such a lack of docs on many of the widget classes and methods? Let me give a practical example from the GtkTreeView class and one other widget: http://developer.gnome.org/doc/API/2.0/gtk/GtkTreeViewColumn.html The description for GtkTreeView column is incomplete. It says: The GtkTreeViewColumn object is a visible column in a GtkTreeView widget. It determines the geometry, type and that's as far as it gets. http://developer.gnome.org/doc/API/2.0/gtk/GtkTreeView.html#GtkTreeView-select-cursor-row here, arg1 and returns are blank.

Re: GtkListStore usage

Hello
I would like to use GtkListStore in this way:
- Create GtkListStore with 1 column (G_TYPE_POINTER)
- Register two functions get_value and set_value. When
gtk_list_store_{get,set}_value is called, my {get,set}_value will be
called, returning a value from the object in column 1 (or generate
a value from the object), and set a value in the object, respectively.
Registering may be connecting to signal or setting a function pointer
in GtkListStore struct, ..
* Or we can create GtkListStore with n+1 columns, and let GtkListStore
check data types instead of {get,set}_value.
- {get,set}_value contain a lot of switches to control each column data.
Is there a way to do this without modifying GtkListStore or implementing
a new GtkTreeModel?
I don't have an answer for you, but I need similar functionality in a
program I'm writing. Plus I need it for multi-column lists as well. Any
info you find out would be of use to me. Similarly, if I find anything
of use, I'll report it to the list for you.
BTW, Gtk(2.0) uses gtktreedatalist to store a row. It would be better if
GtkListStore allows developer to use another type instead of gtktreedatalist
when they want.
Yes, especially if you want to work on data by column instead of by row.

Problems building gnome 2 project with Anjuta
I'm getting some weird compile errors while trying to build a project with Anjuta. It's just a quick test project for playing with GtkTreeView, but I'm getting errors in main.c. The original project was created in Anjuta. I then used Glade 1.1.3 to generate all the files (after I deleted the main.c Anjuta created). I then modified main.c with the code I'm working on. However, when building the project, I get the following errors: /home/carl/Projects/experimenting/src/main.c:49: undefined reference to `create_window1' /home/carl/Projects/experimenting/src/main.c:63: undefined reference to `lookup_widget' This doesn't make sense. create_window1 is in interface.c and lookup_widget is in support.c. interface.h and support.h are included in main.c so why it can't find them is completely strange. I've even shelled out to the console and re-issued configure and make commands to see if that would help. it doesn't. If anyone is interested, the full compressed project and source can be found at: http://www.duckwing.ca/programming/experimenting.tgz (I verified the link works this time ;-) Can anyone tell me what is going on and why this doesn't work? PS: The ENABLE_NLS code that is commented out at the top of main.c also causes problems (which is why it is commented out) but it was generated by Glade so I'm not sure what's up with that. -- .''`.

success with GtkTreeView
Ok, you can ignore my previous message. I did get it work by creating another project (gtk2 only) and copy/paste the relevant code bits in. The good news is I used Glade to create a GtkTreeView object. I then grabbed a pointer to that object using lookup_widget, created a GtkListStore and set the GtkTreeView up to use that list store. I then started creating columns and adding them as showin in Tree and List Widget in the Gtk+ 2.0 API docs on the website, and also some help from some of you (special thanks to Harring Figueirdo on the Glade-Users list -- hmm, Figueirdo, is that Portuguese?) However, one of the things I wanted to try was to set the heading text to be red, like shown in the API reference, but for some reason it doesn't work. See for yourself at: http://www.duckwing.ca/screenshots/gtktreeview.jpg Notice the code behind window1 shows creating the cell renderer and setting the text to red using g_object_set: renderer = gtk_cell_renderer_text_new(); g_object_set( G_OBJECT(renderer), foreground, red, NULL); but when I create the column and append it to the view, the text is not red like I *thought* it should be: column = gtk_tree_view_column_new_with_attributes(Shift, renderer, text, SHIFT_COLUMN, NULL); gtk_tree_view_append_column(GTK_TREE_VIEW(theTreeView), column); This is pretty much straight from the API Reference docs. Any ideas as to why this is happening? Do the headings for the columns maybe not allow this? -- .''`. Carl B.

controlling container sizes
I'm laying out a window in Glade and have it divided up into several sections. However, I can't control the size (width, height) of a specific section. I could use the fixed layout widget, but all the docs I've read say not to use it except on specific needs. Let me show you some examples. http://www.duckwing.ca/screeshots/shot1.jpg http://www.duckiwng.ca/screenshots/shot1-widgets.jpg The first link is the window, the second shows the widget tree for that window. I've used vertical and horizontal separator widgets in the vbox and hbox. It splits the window in exactly half (used the middle item). It would be nice if I could make the left side smaller than the right without doing a whole lot of extra containers and such. In another window, I've used a table container and tried to space things out. However, depending on what widget I put in a container dictates the size of the rest of the row/column for other widgets. so If I put a label widget in first, the column shrinks. Then I put a treeview below it and the column stays shrunk. I can use the treeview properties to make it fill to full width and height for that cell but it would be nice if I could have greater control over that. Any suggestions? -- .''`. Carl B.

The Makefile.in says it was generated from the Makefile.am. There is no configure script, nothing. So the question is, how do I build just the demo without compiling up all of gtk2 which is already installed for me? What nuance am I missing in all this?
