Editing Build Settings in xcode 4 - xcode4

I have been unable to work out how to edit build settings using the pop-up shown below.
I can enter multiple lines in the pop-up by clicking the '+'. My questions are :-
What is the checkbox next to the setting used for?
Once I have entered one or more settings in the pop-up, how do I make them transfer to the setting I am editing. There isn't a 'Save' button, and clicking off the pop-up closes it but doesn't seem to save the entered data.
Thanks

To delete, check the checkbox and click "-".
To make a new one, click "+".
To save, click "Done".

How do I rearrange menu bar options in Qt Designer 5?

I have been unable to figure out how to easily rearrange the menu bar selections that I have created in Qt Designer. Older documentation indicates that I can press the left click mouse button on a selection and then drag and drop it into a new location but this feature does not seem to work in this version.
I am trying to move "Load Database" above the "Exit" option. I would imagine I could just delete the "Exit" menu selection and add it again but I was hoping there would be an easier option in case this happens again.
To do so you need to go in the ui editor.
Then click on File. Press and hold on the item you want to move. Move it.
Below you can see the exact same thing done in QT 4.12.3 and Window 10.
Press file
Press and hold on the desired item
Drag the selected item where you want
Now the 'Save as' is above 'Save'
Select your action in Designer
Press Ctrl + Up/Down
Ctrl + Up/Down is working for me (Qt desinger 5.15.0)

Visual indication for inline buttons

Is there a way to show some visual indication that the inline button has been pressed in telegram bot.
I have a bit which send inline keyboard, and when I press each buttons it works perfectly fine, but there is a slight delay in getting response from the server. As there is no visual indication to show if a button has been pressed, it is confusing for uses to know if the button was pressed and end up pressing the same button several times.
there are different types of inline buttons in Telegram:
Opens URL (with url).
Forward a message (with switch_inline_query).
Insert query at the chat (with switch_inline_query_current_chat).
Button with action (with callback_data).
I suppose you are refering to the last type of button, in that case, if a user press a button you will get the callback_data via CallbackQuery, and that lets you modify the original message with editMessageText to add something like:
Button TEST pressed.
As an alternative way, after you got the callback response at your server, you can use Emoji for showing feedback to your users. Just edit the inline message and edit some relative emoji to the button text.

Inserting an image in GUI using QT Designer

I am new to QtDesigner. I wanted to know how to insert an image in the GUI using QT Designer. I am trying to add a logo. Help would be appreciated.
You can start inserting a label. Next, you right click on it an then click "change rich text...". A new window will pop-up.
Click on the figure Icon "Insert figure".
Now, you have to create a resource file. Click on the Pencil button.
Next, click on the "New resource file" button.
Choose a name and a folder (your working directory would be a good choice) to save it.
Now, click on the "Add prefix" button.
Choose a name for it.
Then, click on the "Add file" button.
And there you go! Click "OK" and you figure should be there.
Just be aware that you should resize your figure to a proper size before using it.
Hope it helps!
The easiest way I've seen so on :
You drag and drop your Label on your window, select the Label, you'll see on the right side of your screen the 'Property Editor' frame and the 'QLabel' menu, you click on pixmap => Choose File..., select a file and that's it.
Make sure you have resized it before, you won't be able to do so in QtDesigner.
Just for you to know I'm just a beginner on PyQT5 / QtDesigner, so that may not be the proper way to do it.
Hope it helps

Try to move on to the 'Save As' Button by pressing TAB. Then press ENTER.
It seem's that the buttons are doing their jobs correctly, but the 'Save As' Button is not touchable for your mouse pointer.
We have found that there is an unvisible element that obviously shall overlaying the 'Select' Button only, but it covers the 'Save As' Button as well. So you are always clicking on this unvisible tag.

What is the proper name for a multibutton?

I'm trying to design a UI in Qt and I can't find anywhere in the designer a button which can be "droped down" like combobox. What I mean by that is that I would like to have this button with his "default" option choosen so if I like it I would have to just click on it but if I would like to choose different option I would be able to clik the little arrow on the right side of this button and then pick option suitable for me at that moment.
You're looking for a QToolButton that has a set of actions or a menu set on it. From the documentation, the QToolButton::ToolButtonPopupMode...
Describes how a menu should be popped up for tool buttons that has a menu set or contains a list of actions.
Of it's values, the two that I see most frequently are DelayedPopup:
After pressing and holding the tool button down for a certain amount of time (the timeout is style dependant, see QStyle::SH_ToolButton_PopupDelay), the menu is displayed. A typical application example is the "back" button in some web browsers's tool bars. If the user clicks it, the browser simply browses back to the previous page. If the user presses and holds the button down for a while, the tool button shows a menu containing the current history list
And MenuButtonPopup:
In this mode the tool button displays a special arrow to indicate that a menu is present. The menu is displayed when the arrow part of the button is pressed.
