I have a wxWidgets form and I have a wxTextCtrl on it, it has left-to-right direction by default. I want to change it to right-to-left Direction.
how can I do this on C++.
You can set the layout direction of any window, like this:
wxWindow::SetLayoutDirection ( wxLayoutDirection dir )
http://docs.wxwidgets.org/trunk/classwx_window.html#a7d494549f7fcfed44af95f8ee364c1f9
dir may be either wxLayout_Default, wxLayout_LeftToRight or wxLayout_RightToLeft.

How would one achieve the same result. I believe the keybinding for macOS Intellij is op+up/down and on windows it is alt+w/d.
Essentially the function highlights the current word, then, with successive presses, expands out to the full string/line/area in-between parenthesis/further out to the next set of parenthesis. Very useful for developing in LISP.
The closest I've gotten is this: https://vi.stackexchange.com/a/19028
Try this plug in: https://github.com/terryma/vim-expand-region
It expands selections based on Vim’s text objects.
Well this may seem comfortable but does not correspondent with the internal logic of vim itself.
See, in vim everything you enter is like a sentence. va{ for example: there is a verb v -> visually select and an object (or movement) { -> paragraph. In this case there is also a modifier a around. You can exchange stuff in this sentence and it will still work vaw, dil, cB and so on. The power of vim is greatly based on that concept.
Of course you can write a function that does vaw first, then S-v and lastly va{ but that will only work with visual selection. It will not work with c or d or anything. So I will recommend to get used to use different keys for different actions.
The visual selection is mostly not needed anyway. Change a paragraph? directly use ca} and so on.
I have found that VI/VA + WOBO (as many times as you need to expand) works similarly. Not as fast but its the same concept and you can even expand/shrink asymmetrically based on your WO's and BO's (Or OW's and OB's depending on how you look at it)
I'm new to programming, and I was wondering how you are able to handle consecutive, timed key presses in order for the character to do something different. For example, in games like 'Super Smash Bros.' you press one button for a character to punch, and if you press it again, they will do their second punch; pressing it once more will result in a kick. How am I able to program this in Scratch 3.0 (preferrably, but an explanation in another programming language might help)?
By the way, if this helps, I am using a 'state' variable in order to handle other animations such as running; I want the character to be able to animate when the timed key presses occur.
Makey makey (in the extensions) does something similar to that, but if you wanted to make your own from scratch (no pun intended) you could do something like this example that I made: https://scratch.mit.edu/projects/382244376/
As stated earlier, makey makey is the only option...
I know, they only have a few selected options
BUT!
try this:
You usually use
when (up right down left v) pressed:
// Do something
Why don't you use
when (join(up up right right left left up down)()) pressed:
// Do Something
Yes, its the join()() block. Fill up the first blank with the combos you want, separated by a space, and leave the 2nd one empty. Drag it into the selectable part of the Makey Makey hat block, and there you go!
When I move my mouse to a row in tree view and stay here for a second, I want to see a floating window. (Like in developer mode.)
How Can I solve it? Any idea?
When you declare your field or fields that get rendered on a listview make sure you give to the __init__ method the help='My Floating Test' argument. That will cause a floating window to be shown when you hover on that field.
For example check:
addons/account/models/account.py
tag_ids = fields.Many2many('account.account.tag', 'account_account_account_tag', string='Tags', help="Optional tags you may want to assign for custom reporting")
The string on the help attribu will be shown on all the views that render this field upon hovering on it and pausing for 1 second.
If you want to modify the window that is shown, you can extend the
t-name="WidgetLabel.tooltip" template that is located in addons/web/static/src/xml/base_common.xml
I would like to move the cursor in between tags in SublimeText. I can't figure out how to do that. Especially in the case of <test></test>. If you move the cursor from one end to the other with alt + left/right the cursor will end up moving to these places. <|test></|test>. But the cursor will never move in between like this <test>|</test>. This marker is | is the cursor in this case.
Is there an easy way of doing that?
Note: I use OSX
If you install the Emmet-plugin for sublime, you can use the shortcut ctrl+alt+j to move between matching tags. Check it out and see if it fits you, Emmet is quite awesome if you do a lot of html by the way.
I am using iText and am very new to it. There have been several situations where I think I could have figured out the problem with my code if I knew what I was doing - I use examples without knowing the workings behind the code, and even as I look at the source I can't figure out what the programmer was thinking.
What does setTextMatrix of contentByteArray in iText do? And how do I figure out the parameter values I need?
For example:
cb.setTextMatrix(1, 0);
The input parameters are x,y coordinates in points, unless CTM scaling was defined.
0,0 would be the bottom left of the template you are referencing.
The position is the 'baseline' of the text, rather than the top or the bottom.
Transcribed from this source:
https://sourceforge.net/p/itext/mailman/message/12855218/
first parameter sets left margin, second parameter sets bottom margin.
