Using VB 6
Am using Frame, Inside that frame am using textbox, combo box, labels.
When I am running the project it will show like "processing".
So I used the picuture box also inside that frame. But Picture box is not showing in the front of textbox, combobox, labels.
I tried, but it is showing only the picture layout, it is not showing the label “processing”
How to set a property for this condition.
Exactly i need, while executing the program it will show like processing then it will display a output.

A label component does not have a window handle -- hWnd, but instead is drawn right on its parent (in this case, the frame component it sounds like).
A combobox, a textbox, and a picturebox all have a window handle (hWnd), so can have a zOrder and appear behind/in front of other components.
I believe the answer to your question is to place the label component inside a picturebox, and then set the zOrder of the picturebox as needed.
It sounds like your label is underneath one of the other controls (your question isn't particular clear) - if that is the case, you need to play with the ZOrder property of your controls to be able to decide which control gets to be on top (i.e. to be displayed). This link gives you an example of how to use this property.

I am a rookie Cocoa guy. I need to design and implement a view which will show collection of labels on Mac OS using Xamarin. These labels will have a text and color associated with them. When shown inside the view, label should expand till it covers whole text and it will be shown with background and foreground colors.
I have attached the picture of this user control on Windows, you can see that labels inside the StackPanel are expanding till they cover the whole text. Hope this gives better idea about my ask.
The $64,000 question is "are these labels controls?" In other words, do you expect the user to click on these to do something, or are they just for display?
If your answer is "just for display", the solution is super simple: Use an NSTextField and programmatically add attributed text (NSAttributedString) to it. Attributed text attaches display properties to runs of text within the field; properties like "background color".
If you want these to be buttons that you can click on, then things get a lot more complicated.
Since you apparently want the button layout to "flow", you might look into imbedding buttons (well, button cells) into an NSTextField using attachments. This is normally how non-text content (say, an image) can be inserted, but with some fiddling it can actually be anything a control cell can draw. See How to insert a NSButton into a NSTextView? (inline).
Warning: this is not a "rookie" topic and will involve control cells and custom event handling.
If I were doing this, I'd probably just create NSButton objects for each label (choosing an appropriate style/look like NSRecessedBezelStyle), create a custom subclass of NSView to contain them, and then override the layout method to position all of the buttons the way I want.
To be thorough, I'd also override the intrinsic size methods so the whole thing could participate in auto-layout, based on the number and size of buttons it contained.
Desired look
I wish to make a toolbar for my app that will contain some simple buttons, each with a single monochromatic icon. Here is an example of some toolbar buttons similar to I'm trying to achieve, from Mail's compose window:
Notice these buttons have a consistent size, inner padding, padding, and shading. This is a pretty consistent style across macOS, present in Mail, Safari, Finder, etc. This leads me to suspect there's a standardized UI component for creating such buttons.
If I use a segmented control, each button looks correct, with each icon being correctly padded:
Now I would like to add individual buttons that match the style.
Attempt 1
My first attempt was to add a "Push Button" (NSButton) to the toolbar:
This resulted in a wide button that's a bit too short, and not lined up with the segmented control:
Attempt 2
My second attempt was to use a segmented control, with only 1 segment.
This resulted in a button that's the right shape, size, etc., but it was off center relative to its label.
Naturally, I can manually adjust the button to match the goal, but I feel like I'm missing something. What's the proper way to create these standard buttons?
This is actually quite easy to do and you were close already.
You can use NSButton for that. Note that it has different styles (defined in NSButton.BezelStyle) to choose from. The default one is the one to use inside windows and modals. But for toolbars, to match the style of segmented controls and search bars, you can choose the style .texturedRounded.
You can also set the style via Interface Builder. Note that you have to select the button itself, not the toolbar item around it.
To get the correct size, you seem to set the icon within the toolbar item, not the button itself.
Here is my result:
So I downloaded CircleView and tried to change the code. The program came with a button, color wheel, 2 sliders, and a view. When ever I add anything (Slider, button, textfield), on run time the things I added wouldn't show up. What am I not doing?
It's a .nib file.
This is the edit page.
This is what I see when running the program.
As you can see, the button and textfield doesn't appear during run time.
By default, when you add a button, the autoresizing mask (aka "springs and struts") are set to the following:
That means that when you resize the window, the button you added will stay in the same spot it originally was, instead of being "pulled" down with the edge of the window. This could potentially cause the buttons or textfields you added to be hidden behind the circle view once you resize the window large enough.
To prevent that from happening you'll want to change the autoresizing mask of the items to be "pinned" to the bottom edge of the window, so that they look like in the following image:
To do that, click on the red I bar at the top of the square to remove it, and then click on the lower I area to turn it on.
Note that you can also select multiple buttons or textfields at one time to change them all at the same time.
I've been struggling for weeks trying to crack this nut so I'm not sure if it's impossible, or if it's my lack of coding chops... or both. I'm not a programmer and I'm a newbie to Dojo Toolkit.
I have a site using the BorderContainer layout. I'm trying to create an effect where I can use a button to open and close a dropdown type box that will contain controls. I need this dropdown to be hidden on page load, and then open when you click the button.
My problem is that when I open the dropdown, it pushes the content pane below it off the bottom of the browser window. I need the lower ContentPane to stay fit within the remaining space of the browser window when the dropdown opens. Additionally, I want the dropdown to sit outside of the scrollable container for the content below it, which is why I have it set up to sit outside a nested BorderContainer below it.
I've created a simplified version of the code to demonstrate my challenge (see link below). If you load the page you can see the center ContentPane scrolls the content. But, if you then click on the button, a dropdown div expands above the content. Then when you scroll, you'll notice that you can't see the full pane because it's in no-man's-land below the bottom of the browser window. I assume that because the div is set to display:none on load, it's size is not accounted for on page load. Then, when you open it by pressing the button, it's size is additive and the pane below doesn't know how to resize or account for the new element.
I've tried using the visibility attribute, but that leaves a gap for the div when it's still closed. I've tinkered with some code that controls the height that shows promise, but each of my dropdown boxes will be different sizes so I'd prefer that the height be set to "auto" rather than a specified pixel size.
Does anyone have any idea how I can accomplish this so that the lower pane will fit in the space without pushing off the screen?
Here's a sample of the page:
http://equium.com/scaffold.html
(I had some problems trying to insert the full HTML page here as a code sample so if that's a preferable way to handle it, and someone can let me know the best way to embed all of that code, I'd appreciate it.)
Thanks is advance, I'd really apprecaite anyone's feedback.
You might want to take a look at dojox.layout.ExpandoPane (though be warned I think it has only worked properly for top and left regions for a while).
Also, I'd suggest simplifying/altering your layout a bit. See example here:
http://jsfiddle.net/taFzv/
(It'd probably need some tweaking to get exactly what you want.)
The real issue you're having is probably that the BorderContainer has no idea that parts of the view resized. ExpandoPane takes care of that by telling the BorderContainer to re-layout after its animation completes.
It works under IE8.0. When dropdown box open, just keep pressing mouse from page and drag to bottom, you could see the content was pushed to out of page. It looks the browser could not detect it and could not add it to "scroll bar" account.
I would suggest taking out all BorderContainers except your top level one, the one with mainPage as the id.
Place your {stuff here} div into the mainPage BorderContainer, after the ContentPane with the Close/Open button. Make sure you make it dojotype dijit.layout.ContentPane, set up layoutpriority, and set region to top. Set the height to 0/x when clicking the Open/Close button, instead of setting display.
Try your page again. If that doesn't fix it, you probably need, a call to layout, resize, or both to indicate to the BorderContainer that it needs to evaluate all its children and size the "center" pane properly. Something like dijit.byId("mainPage").layout(); Do this any time someone presses the Close/Open button, after you have changed the height of any BorderContainer children.
Maybe the dijit.form.DropDownButton would fit your needs. When click the button a tooltip is displayed that can be filled with any content you want. Just as you specified, the dropdown tooltip is only displayed when you click the button, and it doesn't mess with the underlying layout at all. The tooltip sits "on top" of the page.
In order to take a screenshot of a specific window, I need to place a white colored TForm behind that window. What Windows API could I use to change the z-order of my window and place it correctly ?
Try the SetWindowPos() function.
On Delphi you can useSendToBack method, .Top and .Left properties.
form1.Top := ...;
form1.Left := ...;
form1.SendToBack;
procedure SendToBack;
Description
Use SendToBack to change the order of
overlapping controls or forms.
The order in which controls stack on
top of each other (also called the Z
order) depends on the order the
controls are placed on the form. For
example, if you put a label and an
image on a form so that one is on top
of the other, the one that was placed
first on the form becomes the one on
the bottom. Because both the label and
the image are non-windowed controls,
they "stack" as you would expect them
to. Call the SendToBack method for the
top object to move it below the other
object.
The stacking order of two windowed
controls is the same as the stacking
of two non-windowed controls. For
example, if you put a memo on a form,
then put a check box on top of it, the
check box remains on top. Calling
SendToBack for the check box makes the
memo appear on top.
The stacking order of windowed and
non-windowed controls cannot be
mingled. For example, if you put a
memo, a windowed control, on a form,
and then put a label, a non-windowed
control, on top of it, the label
disappears behind the memo. Windowed
controls always stack on top of
non-windowed controls. In this
example, calling the SendToBack method
of the memo does nothing, the label
remains behind the memo.
If the control has the input focus
when the SendToBack method executes,
it loses the input focus.
(Edit: WinSnap is a very good utility for taking and editing screenshots)
If you can get the handle of the window you want in front then I would assume that:
Pseudo Code:
MyAppWindow.BringToFront
followed by
TargetWindow.BringToFront
Should have the desired effect, yes?
