I am working on Linux Operating System. I want to display a dialog box on an item selection from a drop down menu implemented in ncurses, but the problem is that the dialog box fills up the screen with blue background and further nothing can be done.So, is there a way to display ncurses dialog box inside current window preserving existing ncurses components?
Thanks in advance.
You might use CDK (Curses development kit) to the create dialog box. It provides many other widgets that you can use such as,
Alphalist
Button
Buttonbox
Calendar
Entry Field
File Viewer
Floating Scale
Floating Slider
Graph
Histogram etc...

I have on Linux/KDE a installed version of eclipse Mars.2. But there are strong problems with colors. So there is no different between a activated toolbar button and a inactive toolbar button. At example the "Link with editor" button of the "Project Explorer" view has exactly the same background color if the button is selected or not:
Another thing is that I cannot see if a checkbox or radio button is selected or not. It seems that the foreground color for the check/radio box selections is also identical to the background color. So there is in many configuration views no way to find out what's currently selected and wath's not. In the next screenshot at least one of the "Open mode" radio button must be selected (I assume it's "Double click" button):
Note also that the colors are only in eclipse wrong. In other (native) KDE applications I don't have these effects (at example the foreground of check boxes/radio buttons are black - like I have it expected). Also play around with the color settings in KDE "Application Appearance" has no effects ...
How can I change the colors of these stuff?
There is an Eclipse plugin that helps you import downloaded themes from the online marketplace (themes are free).
This is where you can find it: http://eclipsecolorthemes.org/
You may choose whatever eclipse theme fits your needs!
Good luch!
Ok. Found the solution for my problem on following site:
http://www.jroller.com/andyl/entry/mars_on_linux
Mars is the first eclipse version which uses GTK3 (instead of GTK2 like eclipse versions before 4.5). And on the side above Andrey Loskutov wrotes that may be also the GTK theme (widget style) can be also the problem. The Widget style "oxygen-gtk" should be extremly buggy! After changing the widget style (to now "Adwaida") the problems are gone :-)
You can change the Widget style in KDE by opening in the KDE settings: "Application Appearance" and "GTK+ Appearance".
I am trying to use dialog on my Linux box. The output does not seem proper.
If you look at not the whole box outline is in black. Can you please what are some commonly used color settings.
I cannot use whiptail.
dialog by default draws a shadow to imitate a 3-dimensional view (see screenshots). According to the manual page, that is optional:
--no-shadow
Suppress shadows that would be drawn to the right and bottom of
each dialog box.
How can I put an icon in the top left label and make fullscreen? Apple allocates some space on top for the digital clock and back label. I would like to customize it, but I can't find anything in the SDK to enable this.
The top strip of the Watch screen is reserved for displaying the page title, or occasionally links such as "Cancel" by default for modal views, and the clock. It is not possible to hide this.
It is possible to set an empty title for a page. Some settings will alsoplace a background image behind this text (if you set the mode to 'Aspect Fill', at least in the current Xcode 6.2 beta 3). However, the portion of the image at the top of the screen is simply occluded by a black strip, so this does not achieve what you want.
Additionally, Apple have specifically recommended against displaying logos on the Apple Watch screen, with the rationale that the screen is too small to display for the user anything but actual content.
To set the Global tint:
Select the Interface Controller itself in Interface Builder by clicking on the Yellow circle at the top of the view of the screen.
Press Cmd-Opt-1 to display the File Inspector section of the Utilites on the right hand side.
Set the 'Global Tint' option in the section 'Interface Builder Document', as per the screenshot.
Not possible in the first cut but I think it will come later.
It's not actually a back label. The text in the top left of the Watch screen is the title of the current WKInterfaceController. You can change it by using -[WKInterfaceTitle setTitle:], but you are limited to content that is expressible in an NSString (so no UIImages).
It is possible to customise the status bar in watchOS 4.
Select your interface controller in the storyboard
Open the attributes inspector
Check the Full Screen checkbox
After doing this you can add your custom image to the left of the statusbar.
I have a MFC dialog based application. User can change the language of the dialog, and I made this by closing existing dialog, and opening another with changed language. The problem is that the effect in the taskbar is that one icon is removed, and another identical is created in its place. If my application's icon is not the last icon in the task bar it will be perceived as it was moved to the end of taskbar icon set.
I want to retain icon's position in the taskbar, and rather to prevent icon flicker at all from happening. How do I do that?
The application must support OS'es from Windows XP to Windows 7.
EDIT: alternative question for which I would accept an answer is how to create an invisible window that is nevertheless shown in the taskbar, and how to forward relevant window messages from that window to my main window?
Make the dialog a child of another outer parent window. The parent can be a dialog or any other kind of window; all it will be providing is the title bar. If the user tries to resize it it will have to forward resizing commands to the dialog, but otherwise you shouldn't need to do much in the parent window.
Why not replace the dialog with a CFormView instead? That way there's a frame window that wraps around the dialog (which is embedded in a form view) and it's the frame window that owns the taskbar icon.
Create an SDI application that displays a CFormView. Display the dialog in the default language (or whatever langauge the user previously chose) on initialization. When the user chooses the 'change language' option, simply change the form view that's being displayed with a new one.
Bonus feature: with this design, the framework will take care of things like language-specific accelerators and menus for you with no effort on your part.

i want be able to select any color i want, just like the attached pic.
yes i want to learn this c++ or mfc . I find it more powerfull . Could u explain to me exactly how to add it to my project. I also want the color iteslf and it code appers in picture box and textbox.
Thanks
Use CColorDialog class in mfc is used to pick the color from mfc
// Get the selected color from the CColorDialog.
CColorDialog dlg;
if (dlg.DoModal() == IDOK)
{
COLORREF color = dlg.GetColor();
}
This sample will popup dialog to select the color and after selecting the color and click ok button then color variable will contain the selected color.
Use this color in your application.
EDIT
You can customize your combo box or list box to add the color pick tool.
Refer this link : CodeProjectSample
CMFCColorDialog is what you seem to be looking for. To make it act like a drop-down, you'll need to position it below the down-arrow button (e.g., using MoveWindow).
Since you don't seem to have the MFC Feature Pack, check the Ultimate Toolbox at http://www.codeproject.com/KB/MFC/UltimateToolbox.aspx. Its Graphical User Interface classes have a Color Picker.
For Visual Studio versions prior 2008, you can use BCGSoft's color pikcer (http://www.bcgsoft.com). MFC color dialog is based on this one.
I had a similar problem with CMFCColorButton. I added the graphic resource with the ToolBox on my dialog design, but I could't assign a control variable because it did not recognize CMFCColorButton.
The answer was to include afxcolorbutton.h in the header of stdafx.h. Maybe you can fix it in the same way.
I hope this helps
