Polar drawing widget, gearwheel drawing
dear all, I have some Gtk Applications (in C) and now I want to add a functionality for displaying kind of gearwheels with different number oft teeth. Basically this should be an visual support for parameter editing, maybe as a wizard. The gearwheels doesn't have to be very fancy, but I need to draw a arbitrary number of teeth, and I need to adjust the angular position of this. So far I don't need any mouse interaction on the produced graphic, but this request might come. Point is that I don't want to spend a lot of time in this feature, so I am searching for the easiest solution, especially since I never did some pure graphic programming like this, just a little bit 2D plotting with get-extra and normal Widget usage. I thought best for this round thing would be an polar drawing mode. I know that GtkExtra has a polar Plotting capability, but it might be not the right solution for my purpose. Any Suggestion for me? thanks Arne ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Dear all, because of my lazy programming style I sometimes forget or overwirte the comma before the -1 end of line marker for the gtk_tree_model_get or gtk_tree_store_set function. This error can usually not be detected by the c-compilers, so that I had to spend some really unnecessary time to fix this typo.

Re: Gtk_Tree_View, drawing speed
Hello Vlad, an update frequency about 400Hz is absolutely not necessary, and I agree that no human could follow that. My Target is 100ms. This gives an acceptable picture, even if I use later progress bars for visualization. You will defenitliy notice a difference between 100ms and 33ms. If I use numerical values, and even if you can not read the last number, you have some Information, you see that there is a fast change. The other thing is that I have build in the possibilitiy for a Binary Display where I currently use a Toggle Button. In the Future my plan is to change to a LED like view, where you also can notice very short events. Anyway, to achieve 100ms, the maximum possible update Frequency should by higher. At the moment I have just on Object with 12 Elements in my TreeView, but later I want to have more Objects with more Elements in the view, with the current approach I would already touch the boarder. Also I want to reduce the CPU load for this process. Well, an WebVideo with 30 fps and an much more changing pixels requires less CPU load. A feature I plan is also to give the possibility to log Data to a file, but if the visualization causes high CPU load, and therewith high jitter, the quility of this log will be bad One other thing is, I already know that a fast Display is possible, like if I just use 1 Element Objects. Optically there is not so much difference, so what is causing the delay. Did you ever see the Mega-Tunix Project? http://sourceforge.net/projects/megatunix/ They mad some very cool gauges which I used a few years ago, with also more then 10Hz, and acceptable CPU Load, even on a weak Industrial PC regards Arne Am 27.09.2012 13:27, schrieb Vlad Volodin: Hello Arne, Is it really necessary to refresh updates 400 times per second?

Gtk_Tree_View, drawing speed
Dear all, as you might remember from my questions before, I have an application where I use a tree-view to display some data from an external hardware. At the moment the Data are fetched, displayed and the data for the next row in the tree view are fetched. For example, if I have 12 Objects in my Treeview 12 times different data are fetched from the external hardware and displayed. In that case I can see that I get a request rate about 400 requests per second. But this is just If I use flat objects. If I use Objects which have childs in the treeview, then the Update rate goes rapidly down. For example I have a structured object that also fetches Data and displays them on 12 rows, the update rate is going down to below 100. But in fact the effective number updated rows has not changed compared to that case where I have 12 Single Objects. If I collapse some child's in the tree view, I can see the update rate increasing. To give you an better understanding how this application looks like, you can find a screenshot here http://www.pagelnet.de/uctools/a7.html. I followed this issue down to that point that I can definitely say that the gtk_tree_store_set() function causes the delays. My assumption is, that if a row has children, some recursive things are done, maybe every time I update one item the whole hierarchy gets updated etc. To accelerate the speed again, I see following options (of course just if my assumption is somehow correct) 1.) To implement a kind of shadow storage, und just if the data are different to perform the actual gtk_tree_store_set() operation. But I would not prefer this method, it is either not so easy to implement nor is it solving the root cause. 2.) To find a way, to synchronize the invoked cell renderes, so that I just make one drawing update after I set the last Item. For example, I can try to use just one tree_store_set operation per hierarchy (now i have one tree_store_set operation per row), but also for this I have to create a kind of shadow memory. 3.) Implement a own cell-renderer, which can do above things. Do you see any other option? regards Arne. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Re: Gtk_Tree_View, drawing speed
Thank you for this hint, I tried it and indeed I notice a speedup, but just factor ~1,3. There must be something more. I removed all columns expect the Value column, and now I notice a speedup factor of ~3, if I remove just one column, is see a speedup factor of ~2. Now I am sure that there is some processing on cells where the corresponding data in the treestore are not touched. If I remove columns on the first treeview which is using the same tree-store I see no effect. What is interesting that I now notice also a speedup of my single elements objects, there now I can achieve an update rate of 570 requests per second. - - I just noticed that I can't compare the single element objects and structured objects in that way I did before, but anyway, with the column removing I see some potential for speeding up everything. Of course the given value of 570 requests per second is not the design goal of the program. But later I want to have many structured objects in the treeview with an acceptable update rate and not 100% CPU load. regards Arne Am 26.09.2012 10:51, schrieb jcup...@gmail.com: On 26 September 2012 07:09, Arne Pagela...@pagelnet.de wrote: Do you see any other option?

This is great, of course, but there is a performance penalty: whenever the model changes, the view has to rescan the model and recalculate all the heights. If all your rows are the same height, and they might be from looking at your screenshot, you can set the fixed-height hint and get treeview to just sample a single row. http://developer.gnome.org/gtk3/stable/GtkTreeView.html#gtk-tree-view-set-fixed-height-mode John ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Re: gtk_tree_view/store, best way to select all nodes of a branch
I played around with the gtk_tree_selection_select_range functions, but as far
as I have seen this is not working for collapsed elements.
Also I found the handling very difficult for my purpose, and the operation can
be distorted by other mouse movements.
I implemented this now by using the gtk_tree_model_foreach function, probably
not the most efficient method, but at least a working one:
gtk_tree_model_foreach_hierarchy (GtkTreeModel *model,
GtkTreeModelForeachFunc func,
GtkTreePath * path,
gpointer user_data)
The gtk_tree_model_foreach_hierarchy executes the GtkTreeModelForeachFunc func
in a parent-child hierarchy for the parent and each child.
The parameter treepath has to point to one element in the desired hierarchy.
-- code --
typedef struct
{
GtkTreeModelForeachFunc func;
int index;
gpointer user_data;
}t_gtmfh;
gboolean foreach_indices (GtkTreeModel *model, GtkTreePath *path, GtkTreeIter
*iter, gpointer user_data)
{
int ret = 0;
t_gtmfh * gtmfh;
int * ind;
gtmfh = user_data;
ind = gtk_tree_path_get_indices (path);
if (*ind == gtmfh-index)
{
gtmfh-func(model, path, iter, gtmfh-user_data);
}
else if (*ind gtmfh-index)
{
ret = 1;
}
return ret;
}
void gtk_tree_model_foreach_hierarchy (GtkTreeModel *model,
GtkTreeModelForeachFunc func,GtkTreePath * path,gpointer user_data)
{
t_gtmfh gtmfh;
int *ind;
ind = gtk_tree_path_get_indices (path);
gtmfh.func = func;
gtmfh.index = *ind;
gtmfh.user_data = user_data;
gtk_tree_model_foreach (model,foreach_indices,gtmfh);

Use gtk_tree_selection_select_range().
You already have the start path, so, how to get the end path? Use
gtk_tree_model_iter_n_children() and gtk_tree_model_iter_nth_child()
recursively to always move to the last child in the branch. If your
tree is only two-level (as it seems to be) you do not even need to
recurse.

Synchronization of gtk_tree_store add/remove events
Dear all, I have an application where I use a tree-view to display some data from an external hardware. Different Objects can be added or removed to the treestore, each existing object in the treestore has a specific id which is used to get data over some communication interface. It can easily happen, the the user deselects an object in the treestore while this communication is ongoing. This means that my treepath or iter which I rembered befor is not valid anymore after the communication has finished (*1). To avoid access to not existing memory (*2) I currently use gtk_tree_store_iter_is_valid, but the documentation recommends to no use this function. Even I didn't notice any increase of cpu load or timing influence, I want to follow this recommendation. Of course I can think about implementing a selfmade locking mechanism, but every alternative I considered so far which is under all circumstances is not inconvenient for the user requires a queue to store the add / deselect events. For my feeling this is to much overhead for just this function, does anyone see an other alternative? Maybe there is existing some g_lib stuff for this? In my current implementation it would be very good, if gtk_tree_model_filter_convert_iter_to_child_iter would have a return value. It already produces an gtk_warning if the iter could not be converted so why no return value? *1 (the communication itself is handled in a functions called from g_idle_add, so no thread issue etc.) *2 (my application can crash at gtk_tree_model_get, if the iter is not valid) ps: One other Idea I just had while writing this is to add a boolean column to the treestore where I mark columns which should be removed. This I can handle in my communication callback function, together with a column visible flag this will not be noticeable. I allready have 18 columns in the treestore, this would be the 19th, no problem or? Well, If there is no other Idea, thanks for listening. regards Arne ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

gtk_tree_view/store, best way to select all nodes of a branch
Dear all, I am currently searing for the best method to perform an action on one nodes of a branch in a treestore. At the moment the user just selectes one row of my treeview, so I have to determine if this node is part of a branch and then selecting all other nodes of the branch. I found some functions which might be helpfull for that, like gtk_tree_selection_select_range () gtk_tree_selection_selected_foreach () But so far I didn't find any function which helps me to do what I want. I always come to the point where I have either to walk through my treestore manually by iter_next etc. or I have to write some code which examines the gtktreepath string. It would be good, if I can use wildcards on the treepath, eg: 0 1 2:0 2:1:0 2:1:1 3:0:0 now I want to select 2:* or 2* I am just wondering if there is no better support for this, because I think to perform actions on all childs is a common use case.

Colored Statusbar, ugly grip under win32
Hallo I have an Application which uses an GtkStatusBar with resize grip. I wanted to change the background color of the resize grip, so I put the Statusbar into an eventbox. Since the new 2.20 Win32 Bundle, the Resize Grip locks ugly with modified background color, have a look at following screenshots, comparing same project under win (gtk 2.20) and linux (gtk older): http://www.pagelnet.de/scope/scope_win.png http://www.pagelnet.de/scope/scope_lin.png Has someone an idea what I can do here, or where I can report this? regards Arne ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Re: Treeview, different Cell-render per row
Tadej Borovšak schrieb: Hi. My other Idea was to make a new column for the GtkCellRendererToggle, and just show it when needed. Is it possible to hide a one of the renderer? This is how I would do this. Just add one gboolean column to your data store and connect it to cell renderer's visible property. Tadej Hello, thank you for your answer, The first part is easy, but I don't know how I should connect it to the visible property. Do you know an example project where this is done?

Treeview, start editing with any Key, not just Enter or space
Hello, I have a simple treeview, with three columns, all with GtkCellRendererText. I want to start editing a cell by pressing any key (expect arrow key's), not just enter, space or double click. I want the same behavior which is known form spreadsheet applications. I found a solution which works with single instead of double click, but not a solution with just pressing key's. Is there an easy way to do this? regards Arne ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Treeview, different Cell-render per row
Hallo, I have a simple treeview, with three columns, all with GtkCellRendererText. Now I want, in some special row's, a GtkCellRendererToggle, is this possible? Do I have to write a custom renderer, in which I call the RendererText or the RendererToggle? My other Idea was to make a new column for the GtkCellRendererToggle, and just show it when needed. Is it possible to hide a one of the renderer? regards Arne ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Not receving Signals from gtkhsclae
Hello, In my application (win32) I want to use a gtkhscale. I created the application with glade: widget class=GtkHScale id=hscale1 property name=visibleTrue/property property name=can_focusTrue/property property name=adjustment90 0 100 1 10 10/property property name=restrict_to_fill_levelFalse/property signal name=value_changed handler=on_hscale1_value_changed/ /widget and connected the Signal glade_xml_signal_connect (xml, on_hscale1_value_changed,G_CALLBACK (on_hscale1_value_changed)); But i never receive the Signal! The rest of the application works fine, I use a lot of Signals and callbacks, i googled and tried and check, but without success. Can someone give me a hint? regards Arne -- Pt!

gtk_file_chooser_hangs (win32 libgdk-win32-2.0-0.dll)
Hello, i updated my mingw with the new All-in-one bundle on gtk download page. Now i have the problem, that the gtk_file_chooser is not working anymore in my application under win32. I get just a sandglass-curser over it. I get no warning or errormessage on the console. When I am taking older dll's (libgdk-win32-2.0-0.dll and libgtk-win32-2.0-0.dll) from August 26, everything works fine. With the new one from January 8 I have the problem. An idea what could be the problem? regards Arne -- Sensationsangebot verlängert: GMX FreeDSL - Telefonanschluss + DSL für nur 16,37 Euro/mtl.!* http://dsl.gmx.de/?ac=OM.AD.PD003K1308T4569a -- Pt!
