How to design aa progress bar button with gtk3 c code?
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?
