-====== Fluxbox ======
-Fluxbox is a very light window manager, highly customizable (look, shortcuts, etc).
-===== Links =====
-Installation guide for Gentoo :\\

-===== Control your sound card with the keyboard and xosd =====
-''amixer'' enables you to control your sound card, and the ''xosd'' package with ''osd_cat'' command enables you to print some stuff to the screen, even with a bar graph for the volume :
-<code>
-# mute Master and PCM
-Mod4	m	:MacroCmd {ExecCommand amixer sset Master toggle} {ExecCommand amixer sset PCM toggle} {Exec sleep .1s} {Exec echo "Sound `amixer sget Master volume | grep Left: | cut -f 8 -d " "`" | osd_cat -d 1 -p middle -A center -s 1 -u blue -O5}
-Mod4	Shift	m	:MacroCmd {ExecCommand amixer sset PCM toggle} {Exec sleep .1s} {Exec echo "Sound PCM `amixer sget Master volume | grep Left: | cut -f 8 -d " "`" | osd_cat -d 1 -p middle -A center -s 1 -u blue -O5}
-#volume Master
-Mod4	o	:MacroCmd {ExecCommand amixer sset Master 1+}  {Exec sleep .1s}  {Exec osd_cat -d 1 -p middle -A center -s 1 -u blue -O 6 -b percentage -P `amixer sget Master volume | grep Left: | cut -f 7 -d " " | cut -c 2-4` -T "Master: `amixer sget Master volume | grep Left: | cut -c 24-50`"}
-Mod4	i	:MacroCmd {ExecCommand amixer sset Master 1-}  {Exec sleep .1s}  {Exec osd_cat -d 1 -p middle -A center -s 1 -u blue -O 6 -b percentage -P `amixer sget Master volume | grep Left: | cut -f 7 -d " " | cut -c 2-4` -T "Master: `amixer sget Master volume | grep Left: | cut -c 24-50`"}
-#volume PCM
-Mod4	Shift	o	:MacroCmd {ExecCommand amixer sset PCM 1+}  {Exec sleep .1s}  {Exec osd_cat -d 1 -p middle -A center -s 1 -u blue -O 6 -b percentage -P `amixer sget PCM volume | grep Left: | cut -f 7 -d " " | cut -c 2-4` -T "PCM: `amixer sget PCM volume | grep Left: | cut -c 24-50`"}
-Mod4	Shift	i	:MacroCmd {ExecCommand amixer sset PCM 1-}  {Exec sleep .1s}  {Exec osd_cat -d 1 -p middle -A center -s 1 -u blue -O 6 -b percentage -P `amixer sget PCM volume | grep Left: | cut -f 7 -d " " | cut -c 2-4` -T "PCM: `amixer sget PCM volume | grep Left: | cut -c 24-50`"}
-Mod4	p	:ExecCommand xmms -t

-The ''sleep'' command is just used to print the new value after the change. ''cut'' is used to extract the value of the volume for the bar graph.
-===== Configure TwinView/Xinerama/DualScreen =====
-First, emerge fluxbox with the ''xinerama''  USE flag (and you should compile everything with this flag, so set it in ''/etc/make.conf'').
-It will work fine, except that your toolbar could be spread on both screens, then change in ''~/.fluxbox/init'' :
-<code>
-screen0.toolbar.onhead : 2
-</code>
-If you want to have different settings for the two screens, you can copy all ''screen0'' properties to have ''screen1'' properties too.
-===== Make double-click titlebar maximize the window =====
-Instead of shading the window.
-For that, you have to modify the source code of fluxbox. Of course, it is easier if you use a source distribution such as Gentoo ([[gentoo-portage#emerge_step-by-step_for_modifying_source|here]] is explained how to emerge a package and modify sources).
-But you just have to modify two lines in ''Window.cc'' :
-<code C++>
-Window.cc:3954
-+    CommandRef maximize_cmd(new WindowCmd(*this, &FluxboxWindow::maximizeFull));
-     CommandRef shade_cmd(new WindowCmd(*this, &FluxboxWindow::shade));
-Window.cc:4021
--    frame().setOnClickTitlebar(shade_cmd, 1, true); // doubleclick with button 1
-+    frame().setOnClickTitlebar(maximize_cmd, 1, true); // doubleclick with button 1
-</code>
-===== Make Meta-Tab switch between all windows =====
-NOTE: This is fixed in Fluxbox 1.0, this tip is useless now.
-Instead of only switching between visible windows (not minimized).
-One more time, you have to modify the source code, this time there are two lines :
-<code cpp>
-FocusControl.cc:71
--  (opts & FocusControl::CYCLESKIPSHADED) != 0 && win->isShaded() ||
--  win->isFocusHidden()
-+  (opts & FocusControl::CYCLESKIPSHADED) != 0 && win->isShaded() //||
-+ //win->isFocusHidden()
-FocusControl.cc:122
--  if (fbwin && !fbwin->isIconic() &&
-+  if (fbwin && /*!fbwin->isIconic() &&*/
-</code>
-===== Reduce flickering =====
-... during workspace switch.
-Fluxbox deals with workspaces in a quite simple manner: when switching workspace, it hides all windows of the old workspace, and then draw all windows of the new workspace.
-Most of the time when we switch workspace, we can see the background image, and then all new workspace windows displayed one after the other, what is very nasty.
-First thing, show new workspace's windows before hiding old workspace's ones:
-<code cpp>
-Screen.cc:1208
--    currentWorkspace()->hideAll(false);
-Screen.cc:1223
-     currentWorkspace()->showAll();
-+    wksp->hideAll(false);
-</code>
-Second thing, draw windows in their focusing order, in order to draw the front window first:
-<code cpp>
- void Workspace::showAll() {
--    Windows::iterator it = m_windowlist.begin();
--    Windows::iterator it_end = m_windowlist.end();
--    for (; it != it_end; ++it)
--        (*it)->unwithdraw();
-+    FocusControl::FocusedWindows::iterator it = m_screen.focusControl().focusedOrderList().begin();
-+    FocusControl::FocusedWindows::iterator it_end = m_screen.focusControl().focusedOrderList().end();
-+    int workspace = m_screen.currentWorkspaceID();
-+
-+    for (; it != it_end; ++it) {
-+       if ((*it)->fbwindow() && !(*it)->fbwindow()->isIconic() &&
-+            (int)(*it)->fbwindow()->workspaceNumber() == workspace)
-+            (*it)->fbwindow()->unwithdraw();
-+    }
- }
-</code>
-Third thing, only redraw what is necessary (seems to be faster, but I'm not completely sure, and I hope it doesn't break anything) by replacing the deiconify function by a unwithdraw function which does only a fraction of what deiconify does:
-<code cpp>
-Workspace.cc:228
--        (*it)->deiconify(false, false);
-+        (*it)->unwithdraw();
-Window.hh:201
-     void deiconify(bool reassoc = true, bool do_raise = true);
-+    void unwithdraw();
-Window.cc:1522
-+void FluxboxWindow::unwithdraw() {
-+    if (numClients() == 0)
-+        return;
-+
-+    if (oplock) return;
-+    oplock = true;
-+
-+    bool was_iconic = iconic;
-+
-+    m_blackbox_attrib.flags &= ~ATTRIB_HIDDEN;
-+
-+    setState(NormalState, false);
-+
-+    show();
-+
-+    oplock = false;
-+}
-</code>
-I have also tried to draw and clear windows in their general order of focusing, in replacement of the 2 first enhancements, but surprisingly it's less convincing:
-<code cpp>
-Screen.cc:1211
--    currentWorkspace()->hideAll(false);
-+    int workspace = currentWorkspaceID();
-     // set new workspace
-     m_current_workspace = getWorkspace(id);
-+    FocusControl::FocusedWindows::iterator it2 = focusControl().focusedOrderList().begin();
-+    FocusControl::FocusedWindows::iterator it2_end = focusControl().focusedOrderList().end();
-+
-+    for (; it2 != it2_end; ++it2) {
-+        if ((*it2)->fbwindow() && !(*it2)->fbwindow()->isIconic() && !(*it2)->fbwindow()->isStuck())
-+	{
-+            if ((int)(*it2)->fbwindow()->workspaceNumber() == id)
-+	        (*it2)->fbwindow()->unwithdraw();
-+            if ((int)(*it2)->fbwindow()->workspaceNumber() == workspace)
-+	        (*it2)->fbwindow()->withdraw(false);
-+	}
-+    }
--    currentWorkspace()->showAll(win->fbwindow());
-</code>
-===== Full patch for previous tips =====
-ie double click maximizes and reducing flickering.
-To apply the {{fluxbox.patch|patch}}, copy it in the parent of the ''src'' folder, and enter :
-<code>patch -p0 < fluxbox.patch</code>
