I'm new in gtk. I have a noisy image and to reduce it, I use a function from opencv. It has a run time, for example 5 seconds. I want to show progressing the run time by using progress bar. This is my code:
Code:#include <opencv2/opencv.hpp> #include <gtk/gtk.h> #include <time.h> using namespace cv; using namespace std; gboolean Func (gpointer data) { gdouble value; GString *text; //part of code that generate run time clock_t start, end; start = clock(); Mat image, src1, DENO; image = imread("C:/Users/Alireza/Desktop/1.png"); cvtColor(image, src1, CV_RGB2GRAY); fastNlMeansDenoising(src1, DENO, 19, 29, 38); imwrite("DENO.png", DENO); end = clock(); int runtime = ((int)(end - start)) / CLOCKS_PER_SEC; cout << "Time1 = " << runtime << "s" << endl; //part of code that I want to show run time progress by progress bar value = gtk_progress_bar_get_fraction(GTK_PROGRESS_BAR(data)); value += 0.01; if (value > 1.0) { value = 0.0; } text = g_string_new(gtk_progress_bar_get_text(GTK_PROGRESS_BAR(data))); g_string_sprintf(text, "%d%%", (int)(value * 100)); gtk_progress_bar_set_fraction(GTK_PROGRESS_BAR(data), value); gtk_progress_bar_set_show_text(GTK_PROGRESS_BAR(data), TRUE); gtk_progress_bar_set_text(GTK_PROGRESS_BAR(data), text->str); while (gtk_events_pending()) gtk_main_iteration(); return TRUE; } int main(int argc, char *argv[]) { GtkWidget *window; GtkWidget *progressBar; gint timer; gtk_init(&argc, &argv); window = gtk_window_new(GTK_WINDOW_TOPLEVEL); gtk_window_set_title(GTK_WINDOW(window), "GtkProgressBar"); gtk_window_set_default_size(GTK_WINDOW(window), 300, 30); progressBar = gtk_progress_bar_new(); timer = g_timeout_add(100, Func, progressBar); gtk_container_add(GTK_CONTAINER(window), progressBar); gtk_widget_show_all(window); gtk_main(); return 0; }
and this is my image:
But I can't combine these codes together to show progress run time of my project. I'm new in gtk3. Does any one have any thoughts or suggestions on this?
