`GuiTabBar()` is very limiting as a lot of its default values and behavior is hard-coded

[sleeptightAnsiC]

The usage of GuiTabBar() is very limited because its implementation makes a lot of assumptions and hard-codes many default values.

Examples:

1. the width of every entry is hard-coded to 160
   

   raygui/src/raygui.h

   Line 1738 in e4a59f0

   #define RAYGUI_TABBAR_ITEM_WIDTH 160

2. each entry can be clicked in order to close TabBar, this also draws additional button in top-right corner of every entry
   

   raygui/src/raygui.h

   Lines 1780 to 1781 in e4a59f0

   	// Close tab with middle mouse button pressed
   	if (CheckCollisionPointRec(GetMousePosition(), tabBounds) && IsMouseButtonPressed(MOUSE_MIDDLE_BUTTON)) result = i;

3. each entry appears with hard-coded icon at the beginning
   

   raygui/src/raygui.h

   Line 1795 in e4a59f0

   if (GuiButton(RAYGUI_CLITERAL(Rectangle){ tabBounds.x + tabBounds.width - 14 - 5, tabBounds.y + 5, 14, 14 }, GuiIconText(ICON_CROSS_SMALL, NULL))) result = i;

@raysan5 Would it be fine, if I create a PR with more flexible version of this function (e.g. GuiTabBarEx ) ?

Hi

Hi

@mk99987 ?

[mk99987]

Do u know how to increase the text font size in the input field using the GuiTextBox? Please help me.
Is the font size fixed in the input field?

[raysan5]

@sleeptightAnsiC GuiTabBar() was quickly added for convenience for one of my tools and I'm aware it's not much flexible at the moment.

1.the width of every entry is hard-coded to 160

It can be added a check to allow being redefined by user, like so other advance-controls do.

2. each entry can be clicked in order to close TabBar, this also draws additional button in top-right corner of every entry
3. each entry appears with hard-coded icon at the beginning

Yes, added for convenience, maybe some define can be added to avoid that close button if not required, I got inspiration from Notepad++ tabs system.

@raysan5 Would it be fine, if I create a PR with more flexible version of this function (e.g. GuiTabBarEx ) ?

I prefer to minimize/avoid Gui*Ex() versions, if it can be addressed with some config-defines on GuiTabBar() directly, I prefer that approach. Afaik, most tools won't need multiple separate versions of GuiTabBar().

Makes sense.

I'm not very comfortable with global styles yet, but GuiTabBar seems to be hijacking properties from TOGGLE and BUTTON controls. I don't really see anything that could be reused for those cases I mentioned at the moment.

Note: the best "documentation" on styling is probably...

@mk99987 I'll answer your question since I'm already reading this, but I will ignore any other comments not related to TabBar issue. This is not a support forum and your question is not related to this issue. Ask on Raylib's discord/reddit for general help. Please, after reading this, hide your comments as "Off-Topic" just like I did (by clicking ... next to the comment).

Do u know how to increase the text font size in the input field using the GuiTextBox? Please help me.
Is the font size fixed in the input field?

I believe, this is affected by global styling values: DEFAULT TEXT_SIZE. Try using GuiSetStyle(DEFAULT, TEXT_SIZE, 100) right before you call GuiTextBox(). Maybe there is another property I could not find.
