iLiad [ILIAD]GTK developpement

[Olivier78180]

Hello.
I'm a new iliad user and i have to develop a small application.

I have some problems to execute anything on iLiad.

In fact it is running with success if i launch the gtk with console application as mxrvt. but if i try to execute it directly with a script in content listener, it never go on....

i tried with one very simple code..

#include <stdlib.h>
#include <gtk/gtk.h>

void on_activate_entry(GtkWidget *pEntry, gpointer data);
void on_copier_button(GtkWidget *pButton, gpointer data);

int main(int argc, char **argv)
{
    GtkWidget *pWindow;
    GtkWidget *pVBox;
    GtkWidget *pEntry;
    GtkWidget *pButton;
    GtkWidget *pLabel;

    gtk_init(&argc, &argv);

    pWindow = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    gtk_window_set_title(GTK_WINDOW(pWindow), "Le widget GtkEntry");
    gtk_window_set_default_size(GTK_WINDOW(pWindow), 320, 200);
    g_signal_connect(G_OBJECT(pWindow), "destroy", G_CALLBACK(gtk_main_quit), NULL);

    pVBox = gtk_vbox_new(TRUE, 0);
    gtk_container_add(GTK_CONTAINER(pWindow), pVBox);

    /* Creation du GtkEntry */
    pEntry = gtk_entry_new();
    /* Insertion du GtkEntry dans la GtkVBox */
    gtk_box_pack_start(GTK_BOX(pVBox), pEntry, TRUE, FALSE, 0);

    pButton = gtk_button_new_with_label("Copier");
    gtk_box_pack_start(GTK_BOX(pVBox), pButton, TRUE, FALSE, 0);

    pLabel = gtk_label_new(NULL);
    gtk_box_pack_start(GTK_BOX(pVBox), pLabel, TRUE, FALSE, 0);

    /* Connexion du signal "activate" du GtkEntry */
    g_signal_connect(G_OBJECT(pEntry), "activate", G_CALLBACK(on_activate_entry), (GtkWidget*) pLabel);

    /* Connexion du signal "clicked" du GtkButton */
    /* La donnee supplementaire est la GtkVBox pVBox */
    g_signal_connect(G_OBJECT(pButton), "clicked", G_CALLBACK(on_copier_button), (GtkWidget*) pVBox);

    gtk_widget_show_all(pWindow);

    gtk_main();

    return EXIT_SUCCESS;
}

/* Fonction callback execute lors du signal "activate" */
void on_activate_entry(GtkWidget *pEntry, gpointer data)
{
    const gchar *sText;

    /* Recuperation du texte contenu dans le GtkEntry */
    sText = gtk_entry_get_text(GTK_ENTRY(pEntry));

    /* Modification du texte contenu dans le GtkLabel */
    gtk_label_set_text(GTK_LABEL((GtkWidget*)data), sText);
}

/* Fonction callback executee lors du signal "clicked" */
void on_copier_button(GtkWidget *pButton, gpointer data)
{
    GtkWidget *pTempEntry;
    GtkWidget *pTempLabel;
    GList *pList;
    const gchar *sText;

    /* Recuperation de la liste des elements que contient la GtkVBox */
    pList = gtk_container_get_children(GTK_CONTAINER((GtkWidget*)data));

    /* Le premier element est le GtkEntry */
    pTempEntry = GTK_WIDGET(pList->data);

    /* Passage a l element suivant : le GtkButton */
    pList = g_list_next(pList);

    /* Passage a l element suivant : le GtkLabel */
    pList = g_list_next(pList);

    /* Cet element est le GtkLabel */
    pTempLabel = GTK_WIDGET(pList->data);

    /* Recuperation du texte contenu dans le GtkEntry */
    sText = gtk_entry_get_text(GTK_ENTRY(pTempEntry));

    /* Modification du texte contenu dans le GtkLabel */
    gtk_label_set_text(GTK_LABEL(pTempLabel), sText);

    /* Liberation de la memoire utilisee par la liste */
    g_list_free(pList);
}

And the launcher script...

scriptdir=`/usr/bin/dirname $0`
cd $scriptdir
./test

Thanks

I can't try it at the moment, but you might try to change the test script to

scriptdir=`/usr/bin/dirname $0`
cd $scriptdir
./test > output.log 2> error.log

This redirects output and error messages to log files which might point you into the right direction.

the script I'm using is this:

export DISPLAY=:0
export scriptdir=`/usr/bin/dirname $0`
cd $scriptdir
./iViewer fma83_00.jpg

I adapted the mxrvt run.sh

[Olivier78180]

Thanks for your answer.

Thomas => I tried this solution to redirect errror message. But i have not any.

In fact the application is launch and i have the bottom screen progressing bar but it stand in this state and nerver go on.
I have to kill the process manually.

Max => I tried too with the same script as you but i have the same result.

This is strange cause if i start the gtk with mxrvt it is ok and fast.

Is there any rules to follow in the C source ?

Thanks.

hi, I'm new in programing in Iliad, but it seams that you don't refresh the display (ereaders needs a particular refresh, dmDisplay in erdm.h)

this thread speaks about it:

https://www.mobileread.com/forums/sho...highlight=erdm

edit:

ipdf thoes

#include <liberdm/display.h>

dmDisplay(dmCmdPriorUrgent, dmQFull);

[wallcraft]

Are you using the patched libX11 so that x programs refresh the screen automatically when executed in the iliad? This may require setting up a LD_LIBRARY_PATH. One reference to this is in the mrxvt thread here. Note that you may require a liad_refresh.conf .

[Olivier78180]

Max => A refresh problem is possible.
But i'm used to refresh the screen by using bouton or virtual keyboard. This solution is ok when i launch with mxrvt or when i launch the application by a script called in ssh.

wallcraft => Thanks, i didn't know that a patched libX11 exist.


Thanks all.
I will keep news on this post.

[Max]

I'll be waiting for your news, I'm completly lost

BTW. I found that the busy led on the iliad starts blinking when you execute gtk_main, also the progress bars moves (your GtkWindows usualy hides this).
