Big gaps in Menu using GMenu - c

When creating a menu using GMenu (Gnome/Gtk) there is a huge gap left to the labels of the menu items(-> Picture). Any thoughts how to fix this?
#include <gio/gio.h>
#include <glib.h>
#include <glib-object.h>
#include <glib/gi18n.h>
//....
//....
if(title && (action || submenu))
{
GMenuItem *item;
if(submenu)
{
item = g_menu_item_new_submenu (title, G_MENU_MODEL(submenu));
}
else
{
item = g_menu_item_new(title, action);
if (icon != NULL)
{
g_menu_item_set_attribute (item, "icon", "s", icon);
}
}
//.....
//....
Picture

Unfortunately that's the way it's intended to be.
You can stick to the deprecated GtkImageMenuItem which is not problem until you port your app to GTK 4. If you really want to avoid deprecated components, it's possible to wrap an image + label in a GtkBox as suggested by the documentation, although it's not so straightforward, there are some needed quirks to get a decent solution:
You need to use gtk_menu_set_reserve_toggle_size on the menu and set that to FALSE.
Then you need to create the label and image for each menu item, however for items without icons it's necessary to create an image that will act as a filler, i.e. gtk_image_new_from_icon_name ("", GTK_ICON_SIZE_BUTTON)
You can find a fully working sample here.
Note: there is no guarantee this will properly work on GTK 4.

Display automatically input panel, and keep the entry focused on tizen

What i'm trying to achieve is that when a popup is displayed, the input panel (keyboard) appears as well, and when the user start typing it also update the entry content that is on the panel content.
Unfortunately this appear to be quite complex in Tizen.
What I obtained so far is that the popup is displayed, the kepad too, but when I press buttons on the keypad they are not updating the entry.
In order to start real typing even if the keypad is displayed, i have to tap on the entry.
I did many different tries, without success. The following is the first version of the code and i try to list all the changes i tested:
Evas_Object *popup, *layout;
popup = elm_popup_add(parent);
elm_popup_align_set(popup, ELM_NOTIFY_ALIGN_FILL, 1.0);
evas_object_size_hint_weight_set(popup, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND);
elm_object_part_text_set(popup, "title,text", "Use energy");
layout = elm_layout_add(popup);
elm_layout_theme_set(layout, "layout", "drawer", "panel");
evas_object_size_hint_weight_set(layout, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND);
elm_object_content_set(popup, layout);
Evas_Object *entry = elm_entry_add(layout);
set_number_on_entry(entry, 0);
elm_entry_input_panel_layout_set(entry, ELM_INPUT_PANEL_LAYOUT_NUMBERONLY);
elm_entry_input_panel_show(entry);
elm_object_part_content_set(layout, "elm.swallow.content" , entry);
dlog_print(DLOG_INFO, APP_TAG, elm_entry_entry_get(entry));
container->entry = entry;
Evas_Object *button1;
button1 = elm_button_add(popup);
elm_object_text_set(button1, "OK");
elm_object_part_content_set(popup, "button1", button1);
elm_object_style_set(button1, "popup");
evas_object_smart_callback_add(button1, "clicked", ok_pressed_energy, container);
/* Add a "Cancel" button to popup */
button1 = elm_button_add(popup);
elm_object_text_set(button1, "Cancel");
elm_object_part_content_set(popup, "button2", button1);
evas_object_smart_callback_add(button1, "clicked", dismissed_cb, popup);
evas_object_smart_callback_add(popup, "dismissed", dismissed_cb, NULL);
container->popup = popup;
evas_object_show(popup);
elm_object_focus_set(entry, EINA_TRUE);
elm_entry_cursor_end_set(entry);
The first version of the code (the one above) was trying to display the panel while the popup was still creating. So maybe the show call could have impacted on the focus status for the entry.
The following are the changes i tried in order:
I tried to explicitly allow the focus on the entry using:
elm_object_focus_allow_set(entry, EINA_TRUE);
without luck. I also tried to explicitly give the focus to the entry just after the focus allow was set to true, again no success.
I tried to show the panel after the entry was focused (then after the show function for popup was called. Again not working.
Added:
elm_entry_input_panel_enabled_set(entry, EINA_TRUE);
The documentation for that function says:
If true, the input panel is appeared when entry is clicked or has a focus.
Not working
Tried to display the code using the context obtained from the entry with the following code:
Ecore_IMF_Context *imf_context = (Ecore_IMF_Context*)
elm_entry_imf_context_get(entry);
if(imf_context){
dlog_print(DLOG_INFO, APP_TAG , "Imf context");
ecore_imf_context_input_panel_show(imf_context);
}
I tried to post the question also on the Tizen foru, but i still didn't get an answer that solve my problem, this is the link: https://developer.tizen.org/forums/native-application-development/entry-on-popup-focus#comment-27748
What i'm doing wrong? I tried everything but at the moment with no luck. And unfortunately the documentation is not covering this use case (that i think is quite common).
Any help?

Layout issue with Codename One

At this moment I'm only testing my app in the simulator (as I'm having issues with "Send iOS Build" mentioned in another thread [Errors with Codename One "Send iOS Build" and "Send Android Build")
I'm experiencing some layout issues where it is not making use of the width and height correctly. The elements are left-aligned and there is unused space on the right side. And I need to scroll up and down instead of having everything fit within the visual area. Please see images.
The code are:
private final void show() {
loginSignupForm = new Form("Company", new BoxLayout(0));
Tabs loginSignupTabs = new Tabs();
Style loginSignupStyle = UIManager.getInstance().getComponentStyle("Tab");
prepareAndAddSignupTab(loginSignupTabs, loginSignupStyle);
prepareAndAddLoginTab(loginSignupTabs, loginSignupStyle);
loginSignupForm.add(loginSignupTabs);
loginSignupForm.show();
}
private void prepareAndAddLoginTab(Tabs loginSignupTabs, Style loginSignupStyle) {
loginID = new TextField();
loginPassword = new TextField();
Button loginButton = getLoginButton();
Component[] loginComponents = {
new Label("Email Address"),
loginID,
new Label("Password"),
loginPassword,
loginButton,
};
Container loginContainer = BoxLayout.encloseY(loginComponents);
FontImage loginIcon = FontImage.createMaterial(FontImage.MATERIAL_QUESTION_ANSWER, loginSignupStyle);
loginSignupTabs.addTab("Login", loginIcon, loginContainer);
}
What do I need to changenter code heree to get the elements to:
1. expand to the maximum width (no free space on the right)
2. fit within the visual area (for top-to-bottom)
Please note that I'm coding the elements because I find the (new) GUI Builder quite a challenge to use.
Firstly, don't pass a constant value as an argument to Layouts, coz the values might change in future Codename One updates and this will be difficult for you to debug. new BoxLayout(0) should be new BoxLayout(BoxLayout.Y_AXIS) or simply BoxLayout.y().
The above is where the problem arose but not the only problem because BoxLayout doesn't recognize 0 as a valid argument as it has only 3 which are X_AXIS = 1, Y_AXIS = 2, and X_AXIS_NO_GROW = 3.
If you change the above to use BoxLayout.Y_AXIS, it will work, but from the screenshot above, that's not the best solution.
In conclusion, change your code to below:
private final void show() {
loginSignupForm = new Form("Company", new BorderLayout());
Tabs loginSignupTabs = new Tabs();
Style loginSignupStyle = UIManager.getInstance().getComponentStyle("Tab");
prepareAndAddSignupTab(loginSignupTabs, loginSignupStyle);
prepareAndAddLoginTab(loginSignupTabs, loginSignupStyle);
loginSignupForm.add(BorderLayout.CENTER, loginSignupTabs);
loginSignupForm.show();
}

Getting scroll position with sencha architect extjs

I have been trying to get the scroll position of a tree grid in and ext.js application using sencha architect. Originally I wanted to keep the scroll position after a reload so when a user deletes a post it will scroll back to that same spot after reload. I have attempted to use various methods I have searched for but nothing is working. I'm currently testing by having a java script timeout function give me the scroll position after a few seconds, long enough for me to scroll down and console.log the position but it gives me nothing and I'm not showing anything but zero when I go into the dom and look at the tree view object. I have already tried the following
1st: var newcompheight = comboboxeample.getHeight();
2nd: getScroll: function() {
var me = this,
dom = me.dom,
doc = document,
body = doc.body,
docElement = doc.documentElement,
left, top;
if (dom === doc || dom === body) {
// the scrollLeft/scrollTop may be either on the body or documentElement,
// depending on browser. It is possible to use window.pageXOffset/pageYOffset
// in most modern browsers but this complicates things when in rtl mode because
// pageXOffset does not always behave the same as scrollLeft when direction is
// rtl. (e.g. pageXOffset can be an offset from the right, while scrollLeft
// is offset from the left, one can be positive and the other negative, etc.)
// To avoid adding an extra layer of feature detection in rtl mode to deal with
// these differences, it's best just to always use scrollLeft/scrollTop
left = docElement.scrollLeft || (body ? body.scrollLeft : 0);
top = docElement.scrollTop || (body ? body.scrollTop : 0);
} else {
left = dom.scrollLeft;
top = dom.scrollTop;
}
return {
left: left,
top: top
};
3rd: var test = window.pageYOffset;
I have also attempted to setting the keepscroll position property in Sencha architect to true and other things I have googled but nothing is working. Any help would be appreciated.
Use this:
treeGrid.getEl().getScrollTop()

Dynamically populate GraphSource through PopulateGraphSource method - RadDiagram

I am facing an issue where my graph is tree layout and looks fine initially. However, if I choose to change GraphSource upon user input/ clicks using PopulateGraphSource like in the OrgChart example, I get all the nodes stacked on top of each other with no links and all in corner.
I tried resetting graphSource by creating a new one
this.graphSource = new GraphSource();
I also tried to use the Clear method for GraphSource. Neither did solve the problem, I keep having the same issue.
I am using
ObservableCollection<Node> hierarchicalDataSource;
to fill up my GraphSource object.
All I do is create a new one and then call
PopulateGraphSource();
method.

Try calling the Layout method on the diagram control. Here is a little fragment of code
TreeLayoutSettings settings = new TreeLayoutSettings()
{
TreeLayoutType = TreeLayoutType.TreeDown,
VerticalSeparation = 60,
HorizontalSeparation=30
};
if (this.diagram.Shapes.Count > 0)
{
settings.Roots.Add(this.diagram.Shapes[0]);
this.diagram.Layout(LayoutType.Tree, settings);
this.diagram.AutoFit();
//this.diagram.Zoom = 1;
}

Create widget array using Qt Designer?

In Qt Designer I'm creating multiple labels (for instance):
my_label1
my_label2
my_label3
...
my_label n
Then if I want to hide them I do this:
ui->my_label1->hide();
ui->my_label2->hide();
ui->my_label3->hide();
...
ui->my_labeln->hide();
However I would like to define the labels like
my_label[n]
So then I would be able to do this:
for(i=0;i<n;i++)
{
ui->my_label[n]->hide();
}
I read that I can define the widget like:
QLabel* my_label[5];
but is there any way to do the same from Qt Designer?
Thanks in advance!
Finally I decided to do direct assignment:
QLabel* my_label_array[5];
my_label_array[0] = ui->my_label1;
my_label_array[1] = ui->my_label2;
my_label_array[2] = ui->my_label3;
my_label_array[3] = ui->my_label4;
my_label_array[4] = ui->my_label5;
Then I can do for instance:
for(idx=0;idx<6;idx++) my_label_array[idx]->show();
for(idx=0;idx<6;idx++) my_label_array[idx]->hide();
for(idx=0;idx<6;idx++) my_label_array[idx]->setEnabled(1);
for(idx=0;idx<6;idx++) my_label_array[idx]->setDisabled(1);
etc...
Then I was able to perform iterations. I believe is not the cleanest way to do it but given my basic knowledge of Qt is ok for me.
Thank you very much for your answers and your support! This is a great site with great people.
Instead of creating an explicit array, you may be able to name your widgets using a particular scheme and then use QObject::findChildren() on the parent widget to get a list of the widgets you are after.
If you only want to hide widgets, you can put all the widgets you want to hide in an invisible QFrame (set frameShape to NoFrame) and hide them all by calling setVisible(false) on the QFrame. This may cause some unwanted side effects with layouts so you may have to tweak some size policy settings.
In case you are wanting to hide controls so that you can simulate a wizard type UI, you may want to check into QStackedWidget.
I have another dirty workaround for this:
in header file
// .hpp
class UiBlabla : public QWidget {
...
QLabel** labels;
};
in source file
// constructor
ui->setupUi(this);
labels = new QLabel*[10]{ui->label_0, ui->label_1, ui->label_2, ui->label_3,
ui->label_4, ui->label_5, ui->label_6,
ui->label_7, ui->label_8, ui->label_9};
I haven't seen anything in QtDesigner to do that, but there are a couple of relatively easy ways to get that behavior.
1) Simply store the my_labelx pointers (from QtDesigner) in an array (or better, a QVector):
QVector<QLabel*> my_labels;
my_labels.push_back(ui->my_label1);
my_labels.push_back(ui->my_label2);
Then you can iterate through the QVector.
for(int i=0; i < my_labels.size(); ++i) {
my_labels[i]-> hide();
}
// or with QFOREACH
foreach(QLabel* label, my_labels)
label->hide();
There is a little setup needed in terms of adding all the labels to the QVector, but on the plus side you only do that once.
2) Depending on the layout of your gui, you could have all your labels be children of a container object and iterate through the children
