Description

Details

gtk_test_create_simple_window ()

GtkWidget*          gtk_test_create_simple_window       (const gchar *window_title,
                                                         const gchar *dialog_text);

Create a simple window with window title window_title and text contents dialog_text. The window will quit any running gtk_main()-loop when destroyed, and it will automatically be destroyed upon test function teardown.

window_title : Title of the window to be displayed.
dialog_text : Text inside the window to be displayed.
Returns : a widget pointer to the newly created GtkWindow.

Since 2.14


gtk_test_create_widget ()

GtkWidget*          gtk_test_create_widget              (GType widget_type,
                                                         const gchar *first_property_name,
                                                         ...);

This function wraps g_object_new() for widget types. It'll automatically show all created non window widgets, also g_object_ref_sink() them (to keep them alive across a running test) and set them up for destruction during the next test teardown phase.

widget_type : a valid widget type.
first_property_name : Name of first property to set or NULL
... : value to set the first property to, followed by more name-value pairs, terminated by NULL
Returns : a newly created widget.

Since 2.14


gtk_test_display_button_window ()

GtkWidget*          gtk_test_display_button_window      (const gchar *window_title,
                                                         const gchar *dialog_text,
                                                         ...);

Create a window with window title window_title, text contents dialog_text, and a number of buttons, according to the paired argument list given as @... parameters. Each button is created with a label and a ::clicked signal handler that incremrents the integer stored in nump. The window will be automatically shown with gtk_widget_show_now() after creation, so when this function returns it has already been mapped, resized and positioned on screen. The window will quit any running gtk_main()-loop when destroyed, and it will automatically be destroyed upon test function teardown.

window_title : Title of the window to be displayed.
dialog_text : Text inside the window to be displayed.
... : NULL terminated list of (const char *label, int *nump) pairs.
Returns : a widget pointer to the newly created GtkWindow.

Since 2.14


gtk_test_find_label ()

GtkWidget*          gtk_test_find_label                 (GtkWidget *widget,
                                                         const gchar *label_pattern);

This function will search widget and all its descendants for a GtkLabel widget with a text string matching label_pattern. The label_pattern may contain asterisks '*' and question marks '?' as placeholders, g_pattern_match() is used for the matching. Note that locales other than "C" tend to alter (translate" label strings, so this function is genrally only useful in test programs with predetermined locales, see gtk_test_init() for more details.

widget : Valid label or container widget.
label_pattern : Shell-glob pattern to match a label string.
Returns : a GtkLabel widget if any is found.

Since 2.14


gtk_test_find_sibling ()

GtkWidget*          gtk_test_find_sibling               (GtkWidget *base_widget,
                                                         GType widget_type);

This function will search siblings of base_widget and siblings of its ancestors for all widgets matching widget_type. Of the matching widgets, the one that is geometrically closest to base_widget will be returned. The general purpose of this function is to find the most likely "action" widget, relative to another labeling widget. Such as finding a button or text entry widget, given it's corresponding label widget.

base_widget : Valid widget, part of a widget hierarchy
widget_type : Type of a aearched for sibling widget
Returns : a widget of type widget_type if any is found.

Since 2.14


gtk_test_find_widget ()

GtkWidget*          gtk_test_find_widget                (GtkWidget *widget,
                                                         const gchar *label_pattern,
                                                         GType widget_type);

This function will search the descendants of widget for a widget of type widget_type that has a label matching label_pattern next to it. This is most useful for automated GUI testing, e.g. to find the "OK" button in a dialog and synthesize clicks on it. However see gtk_test_find_label(), gtk_test_find_sibling() and gtk_test_widget_click() for possible caveats involving the search of such widgets and synthesizing widget events.

widget : Container widget, usually a GtkWindow.
label_pattern : Shell-glob pattern to match a label string.
widget_type : Type of a aearched for label sibling widget.
Returns : a valid widget if any is found or NULL.

Since 2.14


gtk_test_init ()

void                gtk_test_init                       (int *argcp,

                                                         ...);

This function is used to initialize a GTK+ test program.

It will in turn call g_test_init() and gtk_init() to properly initialize the testing framework and graphical toolkit. It'll also set the program's locale to "C" and prevent loading of rc files and Gtk+ modules. This is done to make tets program environments as deterministic as possible.

Like gtk_init() and g_test_init(), any known arguments will be processed and stripped from argc and argv.

argcp : Address of the argc parameter of the main() function. Changed if any arguments were handled.
argvp : Address of the argv parameter of main(). Any parameters understood by g_test_init() or gtk_init() are stripped before return.
... : currently unused

Since 2.14

widget : valid widget pointer.
Returns : adjustment->value for an adjustment belonging to widget.

Since 2.14


gtk_test_slider_set_perc ()

void                gtk_test_slider_set_perc            (GtkWidget *widget,
                                                         double percentage);

spinner : valid GtkSpinButton widget.
button : Number of the pointer button for the event, usually 1, 2 or 3.
upwards : TRUE for upwards arrow click, FALSE for downwards arrow click.

This function will generate a button click (button press and button release event) in the middle of the first GdkWindow found that belongs to widget. For GTK_NO_WINDOW widgets like GtkButton, this will often be an input-only event window. For other widgets, this is usually widget->window. Certain caveats should be considered when using this function, in particular because the mouse pointer is warped to the button click location, see gdk_test_simulate_button() for details.

For GTK_NO_WINDOW widgets like GtkButton, this will often be an input-only event window. For other widgets, this is usually widget->window. Certain caveats should be considered when using this function, in particular because the mouse pointer is warped to the key press location, see gdk_test_simulate_key() for details.
