I want to create some kind of toolbar, consisting of buttons. I used ButtonBox, and put inside some toggle buttons, color button and one regular button.
I want to accomplish two things:
Make buttons stick together despite window width, without margin between them.
Have rightmost button on the right of the window, and other buttons on the left.
If I didn't wanted second thing, I could just use set_valign so that toolbar would shrink to the right.
I tried adding empty Gtk::Box after color button and allowing it to expand, and this keeps rightmost button on the right, but it still leaves margins between buttons, no matter what parameters for pack_start and pack_end I try - there is two optional boolean parameters, but neither of them seem to do anything.
Here is how it looks normally:
Here is how it looks with empty box:
So what should I do to remove margin between buttons, and is there a better way to keep some buttons on the right, and some on the left?
ButtonBox will always have space between buttons. If you want the buttons without space between, use a regular Box.
Otherwise you did the right thing. Use a Box to move the right button to the edge. Sometimes you can achieve the same affect by using pack_start and pack_end to different buttons, all within the same Box.

I have a 4 way splitter in qt, i want to be able to expand the splitter when a user moves one of the tabs instead of collapsing the other tabs to make room.
This is the default state of the splitter when the program launches:
This is the state of the splitter after I try to expand the left most tab of the splitter.
See how in the second picture the splitter has just smushed the three tabs on the right together to make room for the tab I expanded? Instead of this happening i would like the entire splitter to grow to preserve the size of the 3 tabs on the right and to accommodate the expanding left tab.
One last thing, this splitter is nested inside a scrollarea to accommodate the expanding splitter widget.
Does anyone know how I would go about accomplishing this?
One idea that I had was to keep track of the sizes of the individual tabs before and after the user resizes a splitter and then adjust the size of the entire splitter to reflect the increase or decrease in the adjusted tab and reset the other tabs to what they were prior to the change. However I am not sure how to get the sizes of all of the tabs before and after a resize.
So I am making a Gtkmm application using a Gtk::notebook and during run-time I'm adding new tabs to the notebook. But when I add more tabs than there is space on my screen it just keeps going moving out of the screen.
Now I know most Gtk widgets have a lot of properties that can be configured, so I'am wondering is there such a property for notebook that automatically collapses tabs or scales them in some way to make it fit inside the widget/screen.
If not it would be great if you could give me some pointers to how to implement this functionality myself.
set_scrollable() is your best bet. It will add scrolling arrows on the sides of the tab labels at the top when there isn't enough room to show them all.
Note that GtkNotebook will always ask for enough space to show the contents of all tabs, not just the one that's currently visible. If one of your tab pages is really big (say, contains a 10x10 grid of 100x100 buttons), you won't be able to resize the GtkNotebook smaller than that tab page (in that case, 1000x1000 + the height of the label area), even if the current tab page is just an empty container. All set_scrollable() will do is let you resize smaller than the width needed to show all tab labels at the top.
Put this in your .xml GUI file in the GtkNotebook object:
<property name="scrollable">True</property>
This causes the tabs that go out of screen to be horizontal scrollable by adding arrows beside the last tab at the right and the most left tab at the left.
I am programming a game and I have a tab widget which takes up the majority of the window. I want to use the extra space in the tab bar for buttons. I have the tab widget in a grid layout. To accomplish this, I use the code below in order to remove and add back the button widgets to the desired areas (the solution to someone else's question).
ui->centralLayout->removeWidget(ui->exitButton);
ui->centralLayout->removeWidget(ui->ResizeButton);
ui->centralLayout->addWidget(ui->ResizeButton,0,4, Qt::AlignTop|Qt::AlignRight);
ui->centralLayout->addWidget(ui->exitButton,0,4, Qt::AlignTop|Qt::AlignRight);
This does not work for me; however, because I would like the second widget-- the resize button-- to be just to the left of the exit button. What is occurring is that it instead overlaps the exit button. I simply need to move it 21 pixels to the left and have no idea how!
I tried putting both buttons in a frame and then removing and adding the frame the way I did the buttons. Unfortunately the same functions I used do not exist for the qt frame object.
Here are some pictures of my window.

you are using void QGridLayout::addWidget(QWidget * widget, int row, int column, Qt::Alignment alignment = 0) overload.
2-nd and 3-rd parameters are row and column of a grid. And you put 2 widgets in the same cell so they are overlaping each other.
I solved my problem. Earlier when I was trying to add them to a frame and reposition it I could not but using a widget as the container for my buttons let me place them the way I was earlier attempting to individually place the buttons.
I have RadioGroup with many buttons. Now when I add an item, they become smaller and smaller. How is it possible to make them scrollable?
TRadioGroup does not natively support scrolling. However, what you can do instead is the following:
place a TGroupBox on your UI.
place a TScrollBox onto the TGroupBox, set its Align property to alClient, and its BorderStyle property to bsNone.
place a TRadioGroup onto the TScrollBox, clear its Caption property, and set its Left property to -2 and its Top property to -15 (or whatever the TRadioGroup.Font is set to plus a few extra pixels). This positioning is needed because you cannot turn off the TRadioGroup's borders or the space reserved for its Caption.
Tweak the TScrollBox.HorzScrollBar.Range and TScrollBox.VertScrollBar.Range properties so they do not scroll far enough to see the TRadioGroup's right and bottom borders.
This way, the buttons appear as if they are part of the TGroupBox, but with the added scrollbar(s).
RadioGroup->Items->Count
TRadioGroup component doesn't have an embedded scrollbar, but you can put the radio group on a TScrollBox for a similar effect.
You can use the Buttons collection to refer each button, e.g.
RadioGroup->Buttons[0]->Height = 5;
RadioGroup->Buttons[1]->Top = RadioGroup->Buttons[0]->Top + 10;
Anyway a TComboBox could also be a good choice.
Is there any way to add QActions as a list item on QListWidget?
I want to make a customization window which will show list of actions on a widget for move up, move down, Rename and other options. I'd like to display it on the widget same as it appears as a context menu.
I tried adding it as a list item with icon and text, but the look it not very good:
i) list items with blank icon are not aligning properly, even after adding a blank icon of size 16*16 is not taking up any space and text with icons & w/o icon are not aligning.
ii) I'm unable to add right-pointing black triangle at the right most, in-case of sub-menus cause somehow unicode character for this is not getting displayed on my Linux machine.
That's why I want to add QActions as it are getting popped at original place.
Any suggestions?
Yes I have a suggestion : do not try to make fancy widgets like this, users will not find it intuitive
You should find another way to implement this.
Imo, something like a QToolButton with a QToolButton::MenuButtonPopup popup mode will do the trick. This way, you can embed menu and sub-menus in a widget, using QToolButton::setMenu().
