programatically set xwindows titles

[twobob]

Hi, I know it is possibly to set the titles of X apps that honor the -name and -title parameters, however I would like to change the title of apps programmatically.


EDIT: Solved:

[root@kindle root]# xprop -name LBreakout2 -f WM_NAME 8s -set WM_NAME bob

#! /bin/sh
exec xprop -notype \
-f WM_NAME 8s ':\n title =\? $0\n' \
-f WM_CLASS 8s ':\n appName =\? $0\n className =\? $1\n' \
-f WM_WINDOW_ROLE 8s ':\n stringProperty "WM_WINDOW_ROLE" =\? $0\n' \
WM_NAME WM_CLASS WM_WINDOW_ROLE \
${1+"$@"}

is a handyish shell to adapt to do stuff

however it seems that setting the title after it has been stuck on the background is not enough. nor is toggling the WM_STATE 0 to 1 or vice versa.

[root@kindle us]# xprop -name xeyes

[root@kindle us]#

Thoughts on that gratefully accepted. Lipc? Lua?

Spoiler:

I checked out K5 X apps run on native touch Xorg. also

Thanks.

Perhaps reparenting is the way forward?

simple one liner:

[root@kindle root]# xprop -name LBreakout2 -f WM_NAME 8s -set WM_NAME "bob"


done.

Here's some handy code for more serious code level work.

Spoiler:

#include <string.h>

#include <xcb/xcb.h>
#include <xcb/xcb_atom.h>

int
main ()
{
xcb_connection_t *c;
xcb_screen_t *screen;
xcb_window_t win;
char *title = "Hello World !";
char *title_icon = "Hello World ! (iconified)";



/* Open the connection to the X server */
c = xcb_connect (NULL, NULL);

/* Get the first screen */
screen = xcb_setup_roots_iterator (xcb_get_setup (c)).data;

/* Ask for our window's Id */
win = xcb_generate_id (c);

/* Create the window */
xcb_create_window (c, /* Connection */
0, /* depth */
win, /* window Id */
screen->root, /* parent window */
0, 0, /* x, y */
250, 150, /* width, height */
10, /* border_width */
XCB_WINDOW_CLASS_INPUT_OUTPUT, /* class */
screen->root_visual, /* visual */
0, NULL); /* masks, not used */

/* Set the title of the window */
xcb_change_property (c, XCB_PROP_MODE_REPLACE, win,
WM_NAME, STRING, 8,
strlen (title), title);

/* Set the title of the window icon */
xcb_change_property (c, XCB_PROP_MODE_REPLACE, win,
WM_ICON_NAME, STRING, 8,
strlen(title_icon), title_icon);

/* Map the window on the screen */
xcb_map_window (c, win);

xcb_flush (c);

while (1) {}

return 0;
}

I suppose that could be refactored to do the job

Got xdotool running now on the kindle. maybe that can do that job...

xdotool windowreparent 0x1000003 0x51

looks to work okay.

[twobob]

okay. so after much debating. I think simply minimising the three windows is the best option

Home, Searchbar, Blank background.

(searchbar)
[root@kindle root]# xdotool windowminimize 0xe00033

(titlebar)
[root@kindle /dev]# xdotool windowminimize 0xe0004a

(home)
[root@kindle /dev]# xdotool windowminimize 0x1000024

(blank background)
[root@kindle /dev]# xdotool windowminimize 0xe00003

and then restore them again

[root@kindle root]# xdotool windowactivate 0xe00033
etc..

simple.

That way all the nice TSLIB events get piped to the "topmost app" - which is ours

I am currently playing breakout on my kindle 5 : ) YAY with a working TS interface Joy
