How to make image viewer :-

You need one button , one OpenFileDialog, One WxEdit , WxStaticBitmap

Open Button Code Here:-------

wxString filePath;
int w, h, NewW,NewH;
wxImage img;
int PhotoMaxSize = 250;
if (WxOpenFileDialog1->ShowModal()==wxID_OK){
WxEdit1->SetValue(WxOpenFileDialog1->GetPath());
filePath = WxEdit1->GetValue();
img = wxImage(filePath, wxBITMAP_TYPE_ANY);
w = img.GetWidth();
h = img.GetHeight();
if (w>h){
NewW = PhotoMaxSize;
NewH = PhotoMaxSize * h/w;
}
else{
NewH = PhotoMaxSize;
NewW = PhotoMaxSize * w/h;
}

img = img.Scale(NewW, NewH);
WxStaticBitmap1->SetBitmap(img);
WxStaticBitmap1->Refresh();

}

Python Glade Image Viewer :

import os
import sys
import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk, Gio, GdkPixbuf

class Handler:
def OpenButtonClick(self,button):

dialog = Gtk.FileChooserDialog("Choose a Image",
None,
Gtk.FileChooserAction.OPEN,
(Gtk.STOCK_CANCEL, Gtk.ResponseType.CANCEL,
Gtk.STOCK_OPEN, Gtk.ResponseType.OK))
dialog.set_default_size(600, 300)

response = dialog.run()
if response == Gtk.ResponseType.OK:
pic = dialog.get_filename()
pixbuf = GdkPixbuf.Pixbuf.new_from_file_at_scale(pic,400,400,True)

x.builder.get_object("image1").set_from_pixbuf(pixbuf)

elif response == Gtk.ResponseType.CANCEL:
print("Cancel")

dialog.destroy()

class Example:
def __init__(self):
self.builder=Gtk.Builder()
self.builder.add_from_file("ImageViewer.glade")

self.builder.connect_signals(Handler())

window=self.builder.get_object("window1")
window.show_all()
def main(self):
Gtk.main()

x=Example()
x.main()
