[PATCHSET 0/6] perf report: Add support for callchains on GTK browser (v2)

[Namhyung Kim]

Hi,

This patchset implements callchain support in GTK report browser as
Pekka requested.  Please take a look and give me comments.

v2 changes)
 * fix a bug on percent calculation of children nodes
 * show topmost symbol only when multiple paths exist for a node
 * add alternating background colors (Ingo)
 * put callchain info into existing overhead and symbol column (Arnaldo)

You can get it from 'perf/callchain-gtk-v2' branch on my tree at

 git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git


Any comments are welcome, thanks!
Namhyung

[PATCH 4/6] perf gtk/hists: Make column headers resizable

[Namhyung Kim]

From: Namhyung Kim <namhyung.kim@lge.com>

Sometimes it's annoying to see when some symbols have very wierd long
names.  So it might be a good idea to make column size changable.

[PATCH 6/6] perf gtk/hists: Set rules hint for the hist browser

[Namhyung Kim]

From: Namhyung Kim <namhyung.kim@lge.com>

The 'rules' means that every second line of the tree view has a shaded
background, which makes it easier to see which cell belongs to which
row in the tree view.  It can be useful for a tree view that has a lot
of rows.

perf gtk/hists: Make column headers resizable

Sometimes it's annoying to see when some symbols have very wierd long
names.  So it might be a good idea to make column size changable.

If callchain is displayed, add "row-activated" signal handler for
handling double-click or pressing ENTER key action.

perf gtk/hists: Set rules hint for the hist browser

The 'rules' means that every second line of the tree view has a shaded
background, which makes it easier to see which cell belongs to which
row in the tree view.  It can be useful for a tree view that has a lot
of rows.
