I have a CSliderCtrl and to give the users more information about what they are selecting I wish to have simple text below each Tic to display it's value.
I have done this with simple statics as shown here.
However these are statically placed and I am concerned that under different themes and versions of Windows these will not be aligned correctly.
Is there a way to have the CSliderCtrl print these labels or a way to get the co-ordinates of the Tic marks so that I can align them correctly.
I think the combination of GetNumTics and GetTicPos should give you everything you need. The documentation says the returned position is in client coordinates, so this should be the X coordinate on the slider control client area.

I'm looking for a solution in which custom text is rendered instead of a point for a scatter or bubble diagram using chart.js. For example, if plotting baseball players' batting average vs slugging percentage, I want the player's name to appear centered horizontally and vertically over the underlying x,y coordinate, such as 'MANTLE' or 'RUTH', instead of the typical dot/square/triangle/bubble pointstyles. I noticed a callback function lets me program custom axis labels, but I need to do something similar for the actual point of the graph.
If this is not possible, can you recommend another library that can do this.
Thank you in advance...
chartjs-plugin-datalabels does what you're looking for. The positioning of the labels is largely customizable. A custom label formatter function for example lets you display text other than the data values.
Please take a look at the chartjs-plugin-datalabels samples, especially at Custom Labels.
Keep in mind that this plugin registers itself globally, meaning that once imported, all charts will display labels. In case you want it enabled only for a few charts, you first need to unregister it globally. Then, you can enabled the plugin for specific charts.
I want to make a menu that will take an undetermined quantity of labels and spread them out horizontally so that 3 are visible on screen at once. When pressing left/right it will go to the next one, the one that is selected is always in the center of the screen horizontally with the other two on the left/right of the screen.
The problem is that I also want a smooth transition not just a replacement. They need to wrap endlessly.
Not sure where to begin, not finding examples on google.
The concept you are talking about was popularized by Apple under the name "Cover Flow".
There is a widget like that available under a permissive license here: https://code.google.com/p/pictureflow/
I take it you want something a bit simpler (only show three labels, less fancy 3D effect), but I assume this is a good starting point.
Another one is the PathView QML element:
http://qt-project.org/doc/qt-5/qml-qtquick-pathview.html#details
It is even closer to what you like to do, feature-wise. It is also available in Qt4 and there is a tutorial here: http://qt-project.org/doc/qt-4.8/declarative-modelviews-pathview.html
I'm working on a tool that generates a grid of hexagons that the user can click on to cycle through certain states (Enemy, ally etc). So far, I've been able to generate the hexes as Polygons.
I'm fairly new to Windows programming and the Win32 API. I know how to create a regular button, but what would be the best way to deal with what I need?
The options that come to mind are:
Make the hex's pseudo-buttons. As in store the states of the hex objects and just draw the text on each hex as the user clicks on them.
Make actual hexagon shaped buttons using CreateWindow. I've found some examples of how to create different shaped buttons, but haven't tried myself.
Create image files to cycle through.
What is the correct way to go to do this? By correct I mean best practice.
If you are already drawing the hexagons (it sounds like you are) then making hexagon shaped buttons doesn't really do much for you. You can do the hit testing yourself to determine which pseudo-button was clicked. This avoids having Windows manage many small objects that you already have complete data about. And drawing the text on these buttons will be at least as fast as needing Windows to do it.
I'm developing a Qt application and it's currently in an internal beta test. One member of the company has Windows configured to display text larger than its normal size, which breaks my UI. The About page, for example, currently looks like this:
but under his settings, looks like this (note the clipped text):
Coming from a C#/Winforms background, I'm amazed that I can't seem to find some easily configurable label property such as Form.AutoSize that will automatically size the labels to fit their containing text. I've tried messing with sizePolicy, scaledContents, and a few other properties, but none seem to do this.
I've come across various threads (such as this one) which give instructions for scaling the text to the label, but I want to do the opposite - scale the label to the text to facilitate for those with enlarged text settings like my co-worker. Is there a straightforward way to do this?
There are at least three solutions to this problem.
Use layouts. Their contents are scaled according to the size of the window.
Make a code which is executed whenever window size is changed. In that code, you get the width of the longest text in the window (How?)(another way) and then set window wider than that.
Do the same as in solution #2, but execute the code only when the dialog is shown. After that, alter the window properties so that its size cannot be changed.
I'm working on an application, and part of it is making the user create a shapes such as squares or rectangles. I'm wondering if there is a function in wxwidgets that enable the user to do that. What i want to do is the user will click this button then he/she can draw a square or rectangle in his/her desired size. It is like in paint where you can make your own size in your desired size. Is that possible in wxwidgets and codeblocks? maybe some related links or tutorials or anything that will help. thanks !!
You should use this contrib library:
Object Graphics Library
OGL defines an API for applications that need to display objects connected by lines. The objects can be moved around and interacted with. You can find this in contrib/src/ogl, contrib/include/wx/ogl, and contrib/samples/ogl.
This is the link:

Titles sais context here is "drawing", ok.
But in case you are talking about user-created rectangles as means of selecting stuff (or users end up here while searching for that context), jargon for that is rectangles as selection is "marquee selection", and you would look into Wx::Overlay to accomplish that.
